In this embodiment, an OLT which is a PON communication device compliant with the ITU-T (International Telecommunication Union Telecommunication Standardization Sector) recommendation such as a TWDM-PON (Time and Wavelength Division Multiplexing Passive Optical Network) system is exemplified. Here, OLT is shown as an example of the communication device, but the communication device may be an ONU. Further, the communication device may be either an OLT or an ONU of a PON conforming to the ITU-T recommendation other than the TWDM-PON. For example, the communication device may be either an OLT or an ONU of an PON conforming to an IEEE (The Institute of Electrical and Electronic Engineers) standard such as GE-PON and 10GE-PON. The TC (Transmission Convergence) layer and the PMD (Physical Medium Dependent) layer can be read as layers having corresponding functions.

(Embodiment 1)
FIG. 1 is a diagram showing a basic configuration of a communication device 100 according to the present embodiment. The communication device 100 is an OLT having a DBA function. The communication device 100 includes an execution unit 3 and an instruction unit 5. The execution unit 3 and the instruction unit 5 are connected via an API (not shown in FIG. 1). The execution unit 3 generates grant information according to the instruction from the instruction unit 5, and transmits the generated grant information to the resource allocation target. That is, the execution unit 3 executes a part of the allocation process. The instruction unit 5 instructs the execution unit 3 so that the response of the execution unit 3, that is, the statistical processing result such as the allocation result and the allocation history by the execution unit 3 becomes a desired response according to the telecommunications carrier, the service, and the like. Specifically, the instruction unit 5 is responsible for the allocation of the execution unit 3, the allocation result, the allocation history, the data continuity associated with the allocation, the continuity history, the request, the request history, the information from the external device, and the history of the information from the external device. At least one of them is detected, and the execution unit 3 is instructed to change the process so that the detection result and the desired allocation according to the service policy according to the communication carrier, the service, and the like are obtained. The execution unit 3 corresponds to a functional module having low dependence on at least one of a conforming standard, generation, method, system, device type, and manufacturing vendor. Here, the low-dependency functional module is a functional module that can be commonly used with respect to at least one of a conforming standard, generation, method, system, device type, and manufacturing vendor.

Although the allocation process is illustrated, the effect of this embodiment does not depend on the allocation process. Regardless of the allocation process, this embodiment has the following effects.
1. 1. Instead of developing it as a dedicated device specialized for functions and services as in the past, the functions that make up the access network device will be made into parts.
2. 2. Functions that differ for each service and each carrier are realized by software components that generalize the input / output interface.
3. 3. By increasing the independence between software components, the software components can be operated on a replaceable platform to flexibly and economically realize the required functions according to the service requirements while maintaining the quality of service.

22 to 25 show an example embodying the configuration of FIG. 1. In FIG. 22, reference numeral 201 represents an external hardware component (eg, NG-PON2 BOX), and reference numeral 202 represents general-purpose hardware (eg, White Box Switch). Further, in FIG. 23, reference numeral 203 represents an external hardware component (for example, NG-PON2 module). Further, in FIG. 24, reference numeral 204 represents a dedicated housing. The instruction unit 5 in FIG. 1 corresponds to a FASA (Flexible Access System Architecture) application such as a DBA algorithm, a DWA algorithm, and a setting management application, and the execution unit 3 is a part below the FASA high-speed API or the FASA low-speed API, or hardware. The driver to be driven, etc. corresponds to the following. The API is exemplified by FASA high-speed API and FASA low-speed API, but the API is not limited to these, and the configuration may be different. Note that FIGS. 22 to 25 include an HW (hardware) -dependent driver and an adaptation layer (adaptive layer for FASA API), but this is unnecessary if the driver can be directly driven by the FASA high-speed API or the FASA low-speed API. .. Further, FIG. 26 is an example in which FIG. 1 is rewritten using the FASA application. FIG. 26 shows the FASA application, the FASA-API such as the FASA high-speed API and the FASA low-speed API, and the FASA platform corresponding to the portion below the FASA-API such as the FASA high-speed API and the FASA low-speed API of FIGS. 22 to 25. ing.

Further, another example in which the configuration of FIG. 1 is embodied is shown in FIGS. 36 to 39. In FIG. 36, reference numeral 201a represents an external hardware component (eg, NG-PON2 BOX), and reference numeral 202a represents general-purpose hardware (eg, White Box Switch). FIG. 36 shows an example in which the FASA board is configured by a plurality of hardware (NG-PON2 BOX, White Box Switch). The NG-PON2 BOX and the White Box Switch are connected by a standard protocol such as Ethernet (registered trademark). Functions are added or replaced by adding or replacing the FASA application on the FASA application API of the FASA platform. The middleware for FASA application API is software for absorbing the difference in hardware and software due to the difference in vendor and method, and providing the FASA application API.

Further, in FIG. 37, reference numeral 203a represents an external hardware component (for example, NG-PON2 module). Further, in FIG. 38, reference numeral 204a represents a dedicated housing. The instruction unit 5 in FIG. 1 corresponds to a FASA (Flexible Access System Architecture) application such as a DBA algorithm, a DWA algorithm, and a setting management application, and the execution unit 3 corresponds to a part below the FASA application API, a driver that drives hardware, or the like. It corresponds to the following. The API is exemplified by the FASA application API, but is not limited to them, and the configuration may be different. In FIGS. 36 to 39, the HW (hardware) -dependent driver, the chip-dependent SDK (Software Development Kit), the middleware for the FASA application, and the adaptation layer (the adaptation layer for the FASA application API) are included. If the driver or the like can be driven directly by the FASA application API, the adaptation layer is unnecessary.

Further, FIG. 40 is an example in which FIG. 1 is rewritten using the FASA application. In FIG. 40, the FASA application, the FASA application API, and the FASA platform corresponding to the portion below the FASA application API in FIGS. 36 to 39 are shown. As shown in FIG. 40, the access network device based on FASA is composed of a FASA application and a FASA platform.

The "FASA application" realizes different functions for each service or each telecommunications carrier with software components equipped with a general-purpose input / output interface (FASA application API), and makes it possible to replace them. By adding or replacing according to the service, we can provide services with various requirements quickly and easily.
The "FASA platform" is a basic component of an access device that provides the FASA application API to the FASA application and also provides functions that do not need to be changed according to the service or request because it is standardized. be. In the FASA board, each function constituting the FASA board is realized by hardware or software according to the requirements such as processing performance. Specifically, configuration 1 and configuration 2 shown in FIG. 27 are assumed. In the current configuration in FIG. 27, the entire device needs to be redeveloped in order to add / replace functions.

In configuration 1, the upper part of the FASA application API (FASA application) is the subject of consideration for software componentization, and the configuration of the FASA platform is not the subject of consideration. For example, in the case of an NG-PON2 system with this configuration, the NG-PON2 protocol standardized on the FASA platform is provided, and changes to other PON protocols such as EPON are not considered. Configuration 1 enables flexible and rapid addition / replacement of functions by a FASA application that guarantees expandability by using a general-purpose input / output interface. In the configuration 2, the functions constituting the FASA platform are also made into parts, and are targeted for making into software parts. Configuration 2 enables an architecture that does not require special dedicated hardware by configuring functions other than the FASA application with software components. In either configuration, the FASA application API is the same.

FIG. 28 shows an example in which the FASA board is divided into general-purpose hardware and external hardware components. The access network device (OLT) shown in FIG. 28 is composed of three component categories, "(1) FASA application", "(2) general-purpose hardware", and "(3) external hardware component". By freely combining these, the necessary functions can be provided quickly and easily. In FIG. 28, the “(1) FASA application” is a software component such as wavelength control, band control, OAM and multicast.

"(2) General-purpose hardware" is not limited to access network devices, but is equipped with general-purpose communication functions as common components. By making common parts using general-purpose hardware, it is possible to reduce the frequency of developing new equipment from the component level according to service requirements. In addition, by using common parts, it is expected that the equipment cost will be reduced and the maintenance operation will be simplified by reducing the types of maintenance items. "(2) General-purpose hardware" is, for example, hardware that is not a general-purpose server or an access system-dedicated device such as a White Box Switch, and software such as firmware and an OS required for the hardware, "(1). It is equipped with middleware for FASA application API for "FASA application". "(3) External hardware parts" can be used for functions such as optical transmitter / receiver, which are difficult to implement on "(1) FASA application" or "(2) General-purpose hardware", and "(2) General-purpose". It is implemented separately from "hardware".

The "(3) external hardware component" is hardware other than "(2) general-purpose hardware" such as an optical transmitter / receiver. In the case of realizing a media converter by using a simple optical module as "(3) external hardware parts", software such as an OS installed in "(2) general-purpose hardware", "(1) It will operate using the middleware for FASA application API for "FASA application". On the other hand, when mounting a PON MAC chip on "(3) external hardware", firmware required for the operation of the hardware, software such as OS, and FASA application API for "(1) FASA application". The middleware for use may be installed directly. In any case, for example, by replacing external hardware parts with different transmission capacities and transmission methods according to the service requirements, the FASA board is equipped with the corresponding software parts, that is, the software parts that make up the FASA board are replaced. It is possible to realize an access network with the optimum transmission capacity and transmission method according to the situation while using the same general-purpose hardware.

The meaning of each term explained in the above paragraph is shown below.
-FASA application API (FASA application API): An API that connects the FASA application and the middleware for the FASA application API.
FASA application (FASA application): A replaceable software component realized using the FASA application API.
-FASA platform: A basic component of an access device that provides a FASA application API that can implement a FASA application and provides functions that do not need to be changed according to services or requests because it is standardized. Is.
-Software parts: Software that has the necessary functions in replaceable units.
-Middleware for FASA application API: Software that provides FASA application API to FASA application among FASA platforms. The middleware for the FASA application API provides a means for communication between FASA applications and other functions of the FASA infrastructure, and absorbs differences such as lower layers than the FASA application.
-External hardware parts: Functions that are difficult to mount on general-purpose hardware are mounted separately from general-purpose hardware.
-General-purpose hardware: Hardware that can be used for general purposes, not limited to access network services, such as general-purpose servers and White Box Switch.

In order to support the functions that are used differently for each telecommunications carrier, instead of implementing all the combinations in advance, the access network device having the desired functions is provided by replacing the FASA application as needed. As a telecommunications carrier requirement, high availability is also required for access systems. The protection function is important because it is necessary to migrate without stopping the service not only when dealing with device failures but also when migrating to successor hardware with improved software updates and processing performance of access network devices.
Since the configuration of the network connected to the access network device is different for each telecommunications carrier, it is expected that protection will be performed by different methods and different policies. Therefore, FASA defines an API for protection. FIG. 29 shows an image of replacement of the protection method of the original specification for each business operator by replacing the FASA application (protection application) accompanying the replacement of the middle B business operator. By replacing the FASA application, the protection will be unique to each business operator.

FIG. 2 is a diagram showing a configuration for executing a DBA function included in the communication device 100. As a configuration for executing the DBA function, the communication device 100 includes a state acquisition unit 101, an allocation calculation unit 102, a policy determination unit 103, and a grant processing unit 104. The configuration for executing the DBA function is not limited to this.
The state acquisition unit 101 acquires information regarding the uplink band to be allocated. The state acquisition unit 101 outputs the acquired information as state information to the allocation calculation unit 102. The state acquisition unit 101 includes any or all of the cooperation control unit 1011 and the traffic monitor 1012 and the request processing unit 1013. The state acquisition unit 101 may be configured to have another configuration capable of acquiring information regarding the uplink band to be allocated. Further, a part of the function of the state acquisition unit 101, for example, a part of the cooperation control unit 1011, for example, a function of performing processing such as a calculation for converting information into an uplink band is provided in the allocation calculation unit 102, the policy determination unit 103, and the grant processing unit. It may be arranged in any one of 104 or other.

The cooperation control unit 1011 acquires scheduling information from the mobile system, for example, and calculates the amount of uplink data and the arrival time to reach the ONU. Although the scheduling information is from the mobile system, the information acquired by the cooperation control unit 1011 may be dedicated information customized for OLT from BBU (Base Band Unit) or the like, or BBU and RRH (Remote Radio). It may be information about communication permission, bandwidth, etc. exchanged between the Head), the network side and the UE (User Equipment), the antenna, and the like. The traffic monitor 1012 measures the traffic volume of a predetermined period or a predetermined period / a predetermined or non-predetermined flow that continues, or statistically processes the measurement result. The measurement location and the monitor position may be the same or different, and for example, the results measured at other locations may be integrated as a monitor.

Monitor positions include, for example, PON ASIC hardware, multiplex (separation) parts, switches in OLT, DWA-related hardware, higher-level devices such as concentrator switches, at least virtually lower-level devices including vHGW, and the like. It may be any server equipped with a virtualization function. However, the one closer to the functional unit related to the DBA processing has effects such as high update frequency of the monitor function, low occupancy rate of the transmission line, and low propagation delay. When it is far from the functional unit related to the DBA processing, there are effects such as the ease of consolidating the processing of a plurality of devices, the ease of sharing with other devices, the memory amount, and the less limitation of the register amount. The request processing unit 1013 receives the request from the allocation target, and extracts the request amount related to the allocation of the resource included in the request. For example, the state acquisition unit 101 corresponds to a functional unit that acquires BufOcc from an upstream frame in NG-PON2.

The allocation calculation unit 102 inputs the state information output from the state acquisition unit 101 and the allocation calculation parameters output from the policy determination unit 103. The allocation calculation unit 102 performs bandwidth allocation calculation for each DBA cycle based on the input state information and the allocation calculation parameters. The allocation calculation unit 102 sets the allocation result in the grant processing unit 104. Although it is assumed that the bandwidth is calculated for each DBA cycle here, it means that some allocation opportunity arrives. This also applies to the following description. The arrival of a predetermined allocation opportunity may be the passage of a predetermined time called a DBA cycle or the like, the time may be fixed, variable, or other than time arrival. A request, a monitor amount, or an estimated request in which a specific condition, for example, a request, a monitor amount, an estimated request amount, a predetermined amount of information from the outside, etc. is collected in a predetermined amount or more, or a predetermined amount or less is collected. The amount or the predetermined amount of information from the outside etc. arrived at the predetermined number of times or less, or at the predetermined frequency or more or less, and the processing amount of any of the functional parts became the predetermined value or more or less, the upper side or The congestion state of the lower-level device may be at least or less than a predetermined value, the order of processing may be changed, or a combination thereof.

Allocation calculation parameters are maximum bandwidth setting value, guaranteed bandwidth setting value, fixed bandwidth setting value, maximum bandwidth setting value allocation priority, guaranteed bandwidth setting value allocation priority, fixed bandwidth setting value allocation priority, allocation ratio, unrequired allocation amount ( Allocated bandwidth), allocation order, allocation limit amount, switching instruction of the algorithm to be used, excess or missing value, fairness index value, multiple or single BWmap or transmission amount for each allocation target in a predetermined period (allocation bandwidth) ) Or the transmission start time in a predetermined reference time or the transmission start time and transmission amount (allocated band) in a predetermined reference time, multiple "multiple or single BWmaps, or the transmission amount for each allocation target in a predetermined period (allocated band). ) Or the set to be used from the set of "Transmission start time in a predetermined reference time or Transmission start time and transmission amount (allocated band) in a predetermined reference time", wavelength setting, multiple wavelengths, codes, carrier frequencies, core wires , For each core, for each mode, for each sign and (orthogonal) frequency, or at least some combinations thereof.

Further, the allocation calculation unit 102 outputs the policy determination parameter to the policy determination unit 103. The policy determination parameter is an allocation calculation parameter for modifying the allocation in the execution unit 3 (hardware including the allocation calculation unit 102) or its statistical value to an ideal allocation in the instruction unit 5 (for example, the policy determination unit 103). ) Represents the information required for calculation. The policy-making parameters are, for example, the history of at least one of the results of any stage of past requirements, quotas, utilization, utilization, utilization of unrequired allocations, information from external devices and allocation calculations. Or statistics, etc.

The policy determination unit 103 inputs the policy determination parameter output from the allocation calculation unit 102. The policy determination unit 103 calculates the allocation calculation parameter based on the input policy determination parameter at an arbitrary timing, and outputs the calculated allocation calculation parameter to the allocation calculation unit 102.
The grant processing unit 104 generates a grant based on the allocation result set by the allocation calculation unit 102, and transmits the generated grant. For example, in NG-PON2, the grant processing unit 104 corresponds to a functional unit that creates a BWmap and transmits the created BWmap.

The attribution of each functional unit (state acquisition unit 101, allocation calculation unit 102, policy determination unit 103, and grant processing unit 104) to the execution unit 3 and the instruction unit 5 is different for each use case. That is, whether each functional unit belongs to the execution unit 3 or the instruction unit 5 differs for each use case. An example of a use case is shown in FIG.

FIG. 3 shows each item of the functional block, DBA-API Get, and DBA-API Set for each use case. In this embodiment, three use cases (use case 1, use case 2, and use case 3) will be described as an example. Use case 1 is a linked DBA for MFH (Mobile FrontHaul), use case 2 is NSR-DBA (Non Status Reporting DBA) for MFH, and use case 3 is SR-DBA (Status Reporting DBA) for mass. In use case 3, there are cases of (a) full software (DBA function) and (b) partial software (DBA function). The item of DBA-API Get represents the information acquired by the Get command of DBA-API. The item of DBA-API Set represents the content to be set as the allocation target by the Set command of DBA-API. Here, the arrangement of the function on the hardware is an example, and if processing is possible in terms of performance, it may be implemented by software processing.

In this embodiment, as APIs used for each use case, three types of APIs (low-speed API, high-speed API (for bandwidth allocation opportunity, for example, processing in a fixed or variable cycle related to bandwidth allocation) API and event-driven API. ) Is assumed. A slow API is an API that provides an initialization function or a configuration change function that does not require fast access. The high-speed API is called for each single, multiple, or divided DBA cycle when the bandwidth allocation is periodically performed and the fixed or variable cycle is called the DBA cycle. An API that provides processing functions. The event-driven API is an API that provides an automatic processing function at the time of deleting ONU registration when specific conditions such as initialization and timer completion are satisfied. The API for changing the setting information triggered by the deletion of the ONU registration is the same as the low-speed API for initial setting and the like.

The API is shown in the form of a set (get) and read (set) from the FASA application to the FASA substrate. For example, when setting the DBA cycle, input to the setting / management application from an external controller, the DBA application (instruction unit 5) reads the DBA cycle with the FASA API "get_DbaConfig", and uses the "set_DbaConfig" to read the FASA platform (FASA platform (instruction unit 5). Set the DBA cycle in the execution unit 3).

The API is a common API set regardless of the FASA application to be replaced / added, and the API to be used in each FASA application is selected from the common API set. Therefore, the API of each DBA is the same interface. For example, the low-speed API "get_AllocationDbaConfig" is commonly used by a plurality of DBAs, and the information required for each DBA is used from the response data. The allocation target ID is AllocID in NG-PON2. The config number used in the API is an index of setting parameters, and the correspondence between the index and the setting parameters may or may not be a profile such as a group.

Although not specified in the above example, it is desirable to provide APIs for switching applications and turning on / off some or all functions of applications in, for example, event-driven APIs and low-speed APIs. In addition, it is desirable to have an API such as on_ConfigUpdated that notifies the application of the event, which defines the type of event targeted by the event-driven API and registers the event itself. In addition, as an example of event-driven API, only get API such as changing setting information is shown, but it is desirable to have set API as well. It is also desirable to have an API for error response.

Each use case will be briefly described with reference to FIG.

In addition, hardware (MAC chip) that stores only the functions of the grant processing unit 104 is used. It is shown that the specific example of the information acquired by the Get command is the cooperation information and the like, and the specific example of the content to be set as the allocation target by the Set command is the allocation amount, the transmission start time and the like. The MAC chip is composed of integrated circuits such as LSI (Large Scale Integration).

(Use case 2)

(Use case 3: Full software (of DBA function))
In the case of full software (of the DBA function) of use case 3, a request processing unit 1013 as a state acquisition unit 101, an allocation calculation unit 102, a policy determination unit 103, and a grant processing unit 104 are provided. Then, a DBA-API is provided between the request processing unit 1013 and the grant processing unit 104, and the allocation calculation unit 102. Further, hardware (MAC chip) storing the functions of the request processing unit 1013 and the grant processing unit 104 is used. A specific example of the information acquired by the Get command is a request amount or the like, and a specific example of the content to be set as an allocation target by the Set command is an allocation amount, a transmission start time or the like.

(Use case 3: Partial software (of DBA function))
In the case of partial software (of the DBA function) of use case 3, a request processing unit 1013, an allocation calculation unit 102, a policy determination unit 103, and a grant processing unit 104 are provided as a state acquisition unit 101.

Further, hardware (MAC chip) storing the functions of the request processing unit 1013, the allocation calculation unit 102, and the grant processing unit 104 is used. It is shown that a specific example of the information acquired by the Get command is an allocation calculation parameter or the like, and a specific example of the content to be set as the allocation target by the Set command is a policy determination parameter.

Next, each use case will be described in more detail.
(Use case 1)
In use case 1, as an example, the allocation calculation unit 102 and the policy determination unit 103 are configured as the instruction unit 5, and the grant processing unit 104 is configured as the execution unit 3. The instruction unit 5 acquires cooperation information (DBA-API Get) from the execution unit 3 or an external device, and outputs (DBA-API Set) to the execution unit 3 (grant processing unit 104). When the DBA-API Set is only the allocation amount, the execution unit 3 allocates the transmission start time to each allocation target and generates grant information such as BWmap. When the DBA-API Set has a transmission start time and an allocation amount, it generates grant information according to the transmission start time and the allocation amount of each allocation target as obtained.
Here, Set and Get have been described by taking the exchange led by the instruction unit 5 as an example, but if the exchange is led by the execution unit 3, Set and Get are reversed. In this case, for example, the execution unit 3 may go to the instruction unit 5 at regular intervals using a timer or the like, or the execution unit 3 may get to the instruction unit 5 in response to an event such as an exchange with the ONU. You may go there. This also applies to other use cases, APIs and embodiments.

Further, although the instruction unit 5 shows an example composed of the policy determination unit 103 and the allocation calculation unit 102, the instruction unit 5 is only the policy determination unit 103, and the execution unit 3 further includes the allocation calculation unit 102. It may be configured in. In this case, the DBA-API Set / Get is an allocation calculation parameter and a policy determination parameter, similar to the SR-DBA for mass (partially softened (of the DBA function)) of use case 3 (b) described later. May be good. Further, the cooperation control unit 1011 may be the instruction unit 5. In FIG. 3, the cooperation control unit 1011 is arranged below the DBA-API, but the cooperation control unit 1011 may be a part of the execution unit 3 or a functional unit other than the execution unit 3. It may be a part of the instruction unit 5 that processes the information obtained through the IF different from the API. Further, the input of the cooperation control unit 1011 may be directly output to the grant processing unit 104. The attribution is not limited to the above example.

Examples of API of the cooperation DBA for MFH are shown in FIGS. 4 to 6.
FIG. 4 is a diagram showing an outline of a low-speed API of a cooperative DBA for MFH. As shown in FIG. 4, the low-speed API "get_DbaConfig" has an input of "config number", an output of "set value", and the outline of "get_DbaConfig" is "acquire DBA config information". It is shown. Here, the config number is an index of the setting parameter. Examples of the config information include a DBA cycle and the like. Here, as illustrated in the DBA cycle, it may be a predetermined allocation trigger selection and a condition that triggers the selection. Further, as shown in FIG. 4, in the low-speed API "set_DbaConfig", the input is "config number, setting value", the output is "none", and the outline of "set_DbaConfig" is "DBA config information to be allocated". Is shown to be "set".

Explaining in the form of setting (get) and reading (set) from the instruction unit 5 to the execution unit 3, for example, when setting the DBA cycle, the instruction unit 5 reads the DBA cycle with the FASAAPI "get_DbaConfig" and reads "set_DbaConfig". It is used to set the DBA cycle in the execution unit 3. Further, the low-speed API "get_coperationIfConfig" is a command for acquiring, for example, the operation cycle, operation mode, system name, version of the cooperation destination of the cooperation control unit 1011 and the like.

FIG. 5 is a diagram showing an outline of a high-speed API of a cooperative DBA for MFH. As shown in FIG. 5, in the high-speed API "get_DataSize", the input is "time, allocation target ID", the output is "request amount", and the outline of "get_DataSize" is "acquire the request amount of the allocation target". It has been shown to be. Here, the allocation target ID is identification information for identifying the allocation target. Further, as shown in FIG. 5, in the high-speed API "set_GrantSize", the input is "allocation target ID, allocation amount", the output is "none", and the outline of "set_GrantSize" is "allocation amount for the allocation target". Is shown to be "added to the end of the grant".

When the high-speed API "get_DataSize" is defined individually for each AllocID, the API for the AllocID set at the time of band request is get, and when it is defined in the specified range, the specified AllocID is collectively get. The high-speed API "set_GrantSize" that does not specify the transmission start time is transmitted by the execution unit 3, and the high-speed API "set_GrantSizeAndStartTime" that specifies the transmission start time and the high-speed API "set_StartTime" that specifies the transmission start time are transmitted by the execution unit 3, respectively. Determine the start time.

FIG. 6 is a diagram showing an outline of an event-driven API of a cooperative DBA for MFH. As shown in FIG. 6, in the event-driven API "get_DbaConfig", the input is a "config number", the output is a "set value", and the outline of the "get_DbaConfig" is "acquire DBA config information". It is shown that.

For example, the process of FIG. 7 is performed using the API of the above-mentioned cooperation DBA for MFH. FIG. 7 is a system configuration and an operation sequence diagram of the cooperative DBA for MFH. As shown in FIG. 7, in the cooperation DBA for MFH, the bandwidth allocation satisfying the strict delay regulation is realized by the cooperation between the external device (BBU) and the OLT. Specifically, by notifying the OLT of the radio resource information corresponding to the uplink transmission control information of each UE generated by the external device, the OLT has the transmission request information from the ONU required by the SR-DBA. It is possible to perform DBA without any. As a method of notifying the radio resource information, a method of calculating at least one of the uplink data amount and the arrival time at which the OLT arrives at each ONU after notifying as a parameter of the mobile system, and the uplink data amount and the arrival time from the BBU are calculated. A method of notifying directly is conceivable. In this DBA, an API that can implement a DBA different from the conventional SR / NSR-DBA is required for cooperation with an external device. The above operation is an example and is not limited to this.
In this use case, the cooperation DBA for MFH is used, but the same API may be used as a DBA for other businesses and masses other than MFH.

The API is a common API set regardless of the instruction unit for replacing / adding algorithms and the like, and the API to be used in the instruction unit 5 is selected from the common API set. For example, the low-speed API "get_AllocationDbaConfig" is commonly used by a plurality of DBAs, and the information required for each DBA is used from the response data. The allocation target ID is AllocID in NG-PON2.

(Use case 2)
In use case 2, as an example, the allocation calculation unit 102 and the policy determination unit 103 are configured as the instruction unit 5, and the grant processing unit 104 is configured as the execution unit 3. The instruction unit 5 acquires the traffic amount from the execution unit 3 (DBA-API Get) and outputs it to the execution unit 3 (grant processing unit 104) (DBA-API Set). When the DBA-API Set is only the allocation amount, the execution unit 3 allocates the transmission start time to each allocation target and generates grant information such as BWmap. When the DBA-API Set has a transmission start time and an allocation amount, it generates grant information according to the transmission start time and the allocation amount of each allocation target as obtained.

Here, the instruction unit 5 shows an example composed of the policy determination unit 103 and the allocation calculation unit 102, but the instruction unit 5 is only the policy determination unit 103, and the execution unit 3 further includes the allocation calculation unit 102. It may be configured as follows. The DBA-API Set / Get may be an allocation calculation parameter and a policy determination parameter, as in the SR-DBA for mass (partially softened (of the DBA function)) of use case 3 (b) described later. Further, although the configuration in which the traffic monitor 1012 is provided in the execution unit 3 is shown, the traffic monitor 1012 may be provided in a device such as an external switch.

Examples of API of NSR-DBA for MFH are shown in FIGS. 8 to 10.
FIG. 8 is a diagram showing an outline of a low-speed API of NSR-DBA for MFH. As shown in FIG. 8, the low-speed API "get_DbaConfig" has an input of "config number", an output of "set value", and the outline of "get_DbaConfig" is "acquire DBA config information". It is shown. Further, as shown in FIG. 8, in the low-speed API "set_DbaConfig", the input is "config number, setting value", the output is "none", and the outline of "set_DbaConfig" is "DBA config information to be allocated". Is shown to be "set".

FIG. 9 is a diagram showing an outline of a high-speed API of NSR-DBA for MFH. As shown in FIG. 9, in the high-speed API "get_Traffic", the input is the "monitor number", the output is the "monitor result", and the outline of "get_Traffic" is "acquire the monitor result of the monitor number". It is shown to be. Here, the monitor number is identification information for identifying the monitored object. Further, as shown in FIG. 9, in the high-speed API "set_GrantSize", the input is "allocation target ID, allocation amount", the output is "none", and the outline of "set_GrantSize" is "allocation amount for the allocation target". Is shown to be "added to the end of the grant".

Further, the high-speed API is used when the NSR-DBA for MFH simultaneously accommodates another system and calls a function every DBA cycle. The measurement unit of the high-speed APIs "get_Traffic" and "get_AllocIdTraffic" is arbitrarily set with a particle size from a specific flow of AllocID to the total value of a plurality of ONUs. Mainly, the high-speed API "get_Traffic", for example, a unit not for each AllocID such as the whole OLT, the whole OSU (Optical Subscriber Unit), the whole CT (Channel Termination), and "get_AllocIdTraffic" is a unit below AllocID. "Set_TrafficMonitorConfig" or the like may be set as an API for setting the particle size of the input parameters (monitor unit) of "get_Traffic" and "get_AllocIdTraffic". The same applies to get_Request, get_AllocIdRequestTraffic, get_TimeDataSize, get_DataSize and the like.

FIG. 10 is a diagram showing an outline of an event-driven API of NSR-DBA for MFH. As shown in FIG. 10, in the event-driven API "get_DbaConfig", the input is a "config number", the output is a "set value", and the outline of the "get_DbaConfig" is "acquire DBA config information". It is shown that.

Using the API of NSR-DBA for MFH described above, for example, the processes shown in FIGS. 11 and 12 are performed. 11 and 12 are diagrams showing an operation example of NSR-DBA for MFH by API. 11 and 12 show an outline of two types of NSR-DBA for MFH. These use NSR-DBA based on fixed bandwidth allocation (FBA) to reduce the round-trip delay of the control signal generated by SR-DBA and realize low-delay bandwidth allocation that satisfies the delay requirement of MFH. Specifically, by applying NSR-DBA based on traffic statistical data, it is possible to improve the efficiency of the entire system such as sharing with a mass-oriented system while reducing the excessive allocated bandwidth generated by FBA.

The first NSR-DBA (FIG. 11) simultaneously accommodates a TDD-based mobile system and other systems for mass use and the like. This DBA requires an API that uses traffic statistics at a sampling rate at which the TDD period can be estimated.
The second NSR-DBA (Fig. 12) focuses on the fact that traffic fluctuations are periodic when observed on a time axis of about 1 day to 1 week, and is based on traffic statistics with fixed bandwidth allocation. Estimate and allocate the required bandwidth for the next traffic cycle. This DBA requires an API that uses long-term traffic statistics.
The above operation is an example and is not limited to this.
In this use case, NSR-DBA for MFH is used, but the same API may be used as DBA for businesses and masses other than MFH.

(Use case 3)
In the use case 3, as an example, the allocation calculation unit 102 and the policy determination unit 103 are configured as the instruction unit 5, and the grant processing unit 104 is configured as the execution unit 3. The instruction unit 5 acquires the requested amount from the execution unit 3 (DBA-API Get) and outputs it to the execution unit 3 (grant processing unit 104) (DBA-API Set). When the DBA-API Set is only the allocation amount, the execution unit 3 allocates the transmission start time to each allocation target and generates grant information such as BWmap. When the DBA-API Set has a transmission start time and an allocation amount, it generates grant information according to the transmission start time and the allocation amount of each allocation target as obtained.

Is shown to be "set".

Is shown to be "added to the end of the grant".

FIG. 15 is a diagram showing an outline of an event-driven API of SR-DBA for mass (in the case of full software (of the DBA function)). As shown in FIG. 15, in the event-driven API "get_DbaConfig", the input is a "config number", the output is a "set value", and the outline of the "get_DbaConfig" is "acquire DBA config information". It is shown that.

FIG. 16 is a diagram showing an outline of a low-speed API of SR-DBA for mass (in the case of partial software (of the DBA function)). As shown in FIG. 16, the low-speed API "get_DbaConfig" has an input of "config number", an output of "set value", and the outline of "get_DbaConfig" is "acquire DBA config information". It is shown. Further, as shown in FIG. 16, in the low-speed API "set_DbaConfig", the input is "config number, setting value", the output is "none", and the outline of "set_DbaConfig" is "DBA config information to be allocated". Is shown to be "set".

It is shown that.

For example, the process of FIG. 19 is performed using the API of SR-DBA for mass (full softening (of DBA function) and partial softening (of DBA function)). FIG. 19 is a diagram showing an operation example by API of SR-DBA for mass. In FIG. 19, the requirements at the OLT device level are shown below. As the bandwidth utilization efficiency, the ratio of the output rate from SNI to the bit rate that can transmit the PON section (the full bit rate of the SDU excluding the overhead portion of the PON section) is equal to or higher than the first value. As the UNI-SNI delay (highest priority class), the bit rate is set so that the sum of all ONUs <PON sections of the highest priority class flow rate can be transmitted (for example, within 1500 μsec). Bandwidth fairness is that the allocated bandwidth within one cycle is within the second value for the ideal allocation. As a delay fairness, there is no difference in the allocation order within the DBA cycle. As priority control, low-priority frames and high-priority frames are mixed on the uplink, and only low-priority frames are dropped when congestion occurs. As a specific process, a process as described later may be used.
The above operation is an example and is not limited to this.
In this use case, SR-DBA for mass is used, but the same API may be used as DBA for businesses other than mass and for MFH.

In the above use case, the examples are given separately for MFH and mass, but allocation targets such as ONU, OLT, Alloc-ID, and MLID for MFH and mass may be mixed, and the same allocation target may be used. , Cooperation and NSR and SR may be mixed. The mixture may be coexistence, combination, or switching over time. As for API, at least API to be used may be prepared. For example, Alloc-ID1-5 is a linked DBA for MFH, Alloc-ID 6-10 is an NSR-DBA for mass, and Alloc-ID10-15 is a linked DBA for mass and NSR-DBA for mass depending on the time. By switching, Alloc-ID15-20 may be used in combination with NSR-DBA and SR-DBA for mass. In this case, all APIs used in any Allloc-ID may be provided for all Alloc-IDs, or APIs required for each Alloc-ID may be provided for each API.

As shown in the above use case, the execution unit 3 includes, for example, a grant processing unit 104, and the grant processing unit 104 may generate a BWmap or the like, or generate a frame instructing the ONU to generate a BWmap. You may even go to the process of doing.
The execution unit 3 may include, for example, a Request receiving unit, and the grant processing unit 104 may perform processing such as integration of Request information, or may perform processing up to reading from an uplink frame such as DBRu.
The execution unit 3 includes, for example, a traffic monitor 1012, and the traffic monitor 1012 may perform processing such as integration of monitor information, or may perform up to the monitor.

FIG. 30 is a diagram showing another example of the configuration for executing the DBA function included in the communication device 100. As a configuration for executing the DBA function, the communication device 100 includes a state acquisition unit 101, an allocation calculation unit 102, a policy determination unit 103, and a grant processing unit 104. The configuration for executing the DBA function is not limited to this.
The state acquisition unit 101 acquires information regarding the uplink band to be allocated. The state acquisition unit 101 outputs the acquired information as state information to the allocation calculation unit 102. The state acquisition unit 101 includes any or all of the cooperation control unit 1011 and the traffic monitor 1012 and the declaration processing unit 1014. The state acquisition unit 101 may be configured to have another configuration capable of acquiring information regarding the uplink band to be allocated. Further, a part of the function of the state acquisition unit 101, for example, a part of the cooperation control unit 1011, for example, a function of performing processing such as a calculation for converting information into an uplink band is provided in the allocation calculation unit 102, the policy determination unit 103, and the grant processing unit. It may be arranged in any one of 104 or other.

The cooperation control unit 1011 acquires scheduling information such as radio resource information from a mobile system or the like, for example. If the scheduling information acquired from the mobile system or the like is not the band that reaches the ONU used in the OLT (upstream data amount, arrival time, etc.), the band that reaches the ONU may be calculated, or the DBA may be calculated from the mobile system or mobile system. It may be calculated by an external device other than the FASA platform or mobile system on the way to the application. Although the scheduling information is from the mobile system, the information acquired by the cooperation control unit 1011 may be dedicated information customized for the OLT from the BBU or the like, or between the BBU and the RRH, the network side and the UE, and the antenna. It may be information about communication permission, band, etc. exchanged with each other. The traffic monitor 1012 measures the traffic volume of a predetermined period or a predetermined period / a predetermined or non-predetermined flow that continues, or statistically processes the measurement result. The measurement location and the monitor position may be the same or different, and for example, the results measured at other locations may be integrated as a monitor. Monitor positions include, for example, PON ASIC hardware, multiplex (separation) parts, switches in OLT, DWA-related hardware, higher-level devices such as concentrator switches, at least virtually lower-level devices including vHGW, and the like. It may be any server equipped with a virtualization function. However, the one closer to the functional unit related to the DBA processing has effects such as high update frequency of the monitor function, low occupancy rate of the transmission line, and low propagation delay. When it is far away, the ease of consolidating the processes of a plurality of devices, the ease of sharing with other devices, and the amount of memory have the effects of less limitation on the amount of registers. The declaration processing unit 1014 receives the declaration regarding the uplink to be allocated, and extracts the request amount regarding the allocation of the resources included in the declaration. For example, the state acquisition unit 101 corresponds to a functional unit that acquires BufOcc from an upstream frame in NG-PON2.

The allocation calculation unit 102 inputs the state information output from the state acquisition unit 101 and the allocation calculation parameters output from the policy determination unit 103. The allocation calculation unit 102 performs bandwidth allocation calculation for each DBA cycle based on the input state information and the allocation calculation parameters. The allocation calculation unit 102 sets the allocation result in the grant processing unit 104. Although it is assumed that the bandwidth is calculated for each DBA cycle here, it means that some allocation opportunity arrives. This also applies to the following description. The arrival of a predetermined allocation opportunity may be the passage of a predetermined time called a DBA cycle or the like, the time may be fixed, variable, or other than time arrival. Specific conditions, such as requirements, monitor amount, estimated request amount, predetermined information amount from the outside, etc. gathered above or below the predetermined amount, request, monitor amount, estimated request amount, external, etc. A device on the upper or lower side, such as when a predetermined amount of information arrives at a predetermined number of times or less or at a predetermined frequency or more or less, or when the processing amount of any of the functional units becomes a predetermined value or more or less. The congestion state of the above may be equal to or less than a predetermined value, or the order of processing may be changed, or a combination thereof.

The allocation calculation parameters are the same as above, maximum bandwidth setting value, guaranteed bandwidth setting value, fixed bandwidth setting value, maximum bandwidth setting value allocation priority, guaranteed bandwidth setting value allocation priority, fixed bandwidth setting value allocation priority, allocation ratio, Unrequired allocation amount (allocation bandwidth), allocation order, allocation limit amount, switching instruction of the algorithm to be used, excess or loss value, fairness index value, multiple or single BWmap or each allocation target in a predetermined period Transmission amount (allocated band) or transmission start time in a predetermined reference time or transmission start time and transmission amount (allocated band) in a predetermined reference time, multiple "multiple or single BWmaps or each allocation target in a predetermined period" The set to be used from the set of "transmission start time (allocated band) or transmission start time in a predetermined reference time or transmission start time and transmission amount (allocated band) in a predetermined reference time", frequency setting, multiple frequencies, codes, Setting of carrier frequency, core wire, core, mode, sign and (orthogonal) frequency, or at least a part of them.

Further, the allocation calculation unit 102 outputs the policy determination parameter to the policy determination unit 103. The policy determination parameter is an allocation calculation parameter for modifying the allocation in the execution unit 3 (hardware including the allocation calculation unit 102) or its statistical value to an ideal allocation in the instruction unit 5 (for example, the policy determination unit 103). ) Represents the information required for calculation. The policy-making parameters are, for example, the history of at least one of the results of any stage of past requirements, quotas, utilization, utilization, utilization of unrequired allocations, information from external devices and allocation calculations. Or statistics, etc.

The policy determination unit 103 inputs the policy determination parameter output from the allocation calculation unit 102. The policy determination unit 103 calculates the allocation calculation parameter based on the input policy determination parameter at an arbitrary timing, and outputs the calculated allocation calculation parameter to the allocation calculation unit 102.
The grant processing unit 104 generates a grant based on the allocation result set by the allocation calculation unit 102, and transmits the generated grant. For example, in NG-PON2, the grant processing unit 104 corresponds to a functional unit that creates a BWmap and transmits the created BWmap.

The attribution of each functional unit (state acquisition unit 101, allocation calculation unit 102, policy determination unit 103, and grant processing unit 104) to the execution unit 3 and the instruction unit 5 is different for each use case. That is, whether each functional unit belongs to the execution unit 3 or the instruction unit 5 differs for each use case. An example of a use case is shown in FIG.
FIG. 31 shows each item of the functional block, DBA-API Get, and DBA-API Set for each use case. In this embodiment, three use cases (use case 1, use case 2, and use case 3) will be described as an example. Use case 1 is an optical mobile cooperation DBA for MFH, use case 2 is NSR-DBA for MFH, and use case 3 is SR-DBA for mass. In use case 3, in addition to the case of (a) full software (DBA function), only a part (method determination unit) of DBA is implemented as the same configuration as the conventional PON MAC chip or the like (method determination unit). b) The case of partial software (DBA function) is shown. It should be noted that use cases 1 and 2 may be partially softened in the same manner as in 3. The item of DBA-API Get represents the information acquired by the Get command of DBA-API. The item of DBA-API Set represents the content to be set as the allocation target by the Set command of DBA-API. Here, the arrangement of the function on the hardware is an example, and if processing is possible in terms of performance, it may be implemented by software processing.

DBA is a process of allocating the upstream band (transmissible time slot) of each ONU, and uses SR-DBA that dynamically allocates the band to each ONU based on the report from the ONU and the report from the ONU. It can be classified as not NSR-DBA. In SR-DBA, which dynamically allocates bandwidth to each ONU based on the declaration from the ONU, it is possible to allocate bandwidth with high bandwidth utilization efficiency according to the declaration of the ONU, while it is possible to make a round trip of the control signal between the OLT and the ONU. It takes time. Therefore, it is difficult to satisfy the delay regulation of MFH. Therefore, this is an example of an optical mobile cooperation DBA that acquires information necessary for bandwidth allocation from an external device, and an NSR-DBA that allocates bandwidth based on traffic prediction.
In order to support the above use cases, the FASA platform has a linkage control function and a traffic monitor function in addition to the declaration processing function and grant processing function specified in the PON standard, and acquires linkage information and traffic volume. , Request amount acquisition, allocation calculation parameter acquisition, allocation amount setting, transmission start time setting, policy determination parameter setting API must be provided.

The API is shown in the form of a set (get) and read (set) from the FASA application to the FASA substrate. For example, when setting the DBA cycle, input to the setting / management application from an external controller, the DBA application (instruction unit 5) reads the DBA cycle with the API "get_DbaConfig", and uses the API "set_DbaConfig" to use the FASA platform (FASA platform (instruction unit 5). Set the DBA cycle in the execution unit 3).

The API is a common API set regardless of the FASA application to be replaced / added, and the API to be used in each FASA application is selected from the common API set. In this embodiment and other examples, ITU-T is mainly described, but IEEE is also a target. Therefore, the API of each DBA is the same interface. For example, the API "get_AllocationDbaConfig" is commonly used by a plurality of DBAs, and the information required for each DBA is used from the response data. The allocation target ID is AllocID in NG-PON2. The config number used in the API is an index of setting parameters, and the correspondence between the index and the setting parameters may or may not be a profile such as a group.

Although not specified in the example, it is desirable to provide an API for replacing the application and turning on / off a part or all of the functions of the application. For example, API "on_Killed". This is related to the data transfer process at the time of replacing the DBA application, and executes a process that cannot be realized simply by "not executing on_Process", such as calculation of the cumulative allocation amount. In addition, it is desirable to have an API such as "on_ConfigUpdated" that notifies the application of the event, which defines the type of event targeted by the API and registers the event itself. Further, as an example of API or the like, only the API of get such as changing the setting information is illustrated, but it is desirable to include the API of set. It is also desirable to have an API for error response.

Each use case will be briefly described with reference to FIG. 31.
(Use case 1)
In use case 1, a cooperation control unit 1011 as a state acquisition unit 101, an allocation calculation unit 102, a policy determination unit 103, and a grant processing unit 104 are provided.

A specific example of the information acquired by the Get command is cooperation information, and a specific example of the content to be set as the allocation target by the Set command. It shows that it is the allocation amount, the transmission start time, and the like. The MAC chip is composed of LSI.

(Use case 2)

Then, a DBA-API is provided between the traffic monitor 1012, the grant processing unit 104, and the allocation calculation unit 102. Further, the stored hardware (MAC chip) is used for the functions of the traffic monitor 1012 and the grant processing unit 104. A specific example of the information acquired by the Get command is the traffic amount, and a specific example of the content to be set as the allocation target by the Set command is the allocation amount, the transmission start time, and the like.

(Use case 3: Full software (of DBA function))
In the case of full software (of the DBA function) of use case 3, a declaration processing unit 1014, an allocation calculation unit 102, a policy determination unit 103, and a grant processing unit 104 are provided as a state acquisition unit 101. Then, a DBA-API is provided between the declaration processing unit 1014 and the grant processing unit 104 and the allocation calculation unit 102. Further, the stored hardware (MAC chip) is used for the functions of the declaration processing unit 1014 and the grant processing unit 104. A specific example of the information acquired by the Get command is a request amount or the like, and a specific example of the content to be set as an allocation target by the Set command is an allocation amount, a transmission start time or the like.

(Use case 3: Partial software (of DBA function))
In the case of partial software (of the DBA function) of use case 3, a declaration processing unit 1014, an allocation calculation unit 102, a policy determination unit 103, and a grant processing unit 104 are provided as a state acquisition unit 101. Then, a DBA-API is provided between the allocation calculation unit 102 and the policy determination unit 103. Further, the stored hardware (MAC chip) is used for the functions of the declaration processing unit 1014, the allocation calculation unit 102, and the grant processing unit 104. It is shown that a specific example of the information acquired by the Get command is an allocation calculation parameter or the like, and a specific example of the content to be set as the allocation target by the Set command is a policy determination parameter.

Next, each use case will be described in more detail.
(Use case 1)
In use case 1, as an example, the allocation calculation unit 102 and the policy determination unit 103 are configured as the instruction unit 5, and the grant processing unit 104 is configured as the execution unit 3. The instruction unit 5 acquires cooperation information (DBA-API Get) from the execution unit 3 or an external device, and outputs (DBA-API Set) to the execution unit 3 (grant processing unit 104). When the DBA-API Set is only the allocation amount, the execution unit 3 allocates the transmission start time to each allocation target and generates grant information such as BWmap. When the DBA-API Set has a transmission start time and an allocation amount, it generates grant information according to the transmission start time and the allocation amount of each allocation target as obtained.
Here, Set and Get have been described by taking the exchange led by the instruction unit 5 as an example, but if the exchange is led by the execution unit 3, Set and Get are reversed. In this case, for example, the execution unit 3 may go to the instruction unit 5 at regular intervals using a timer or the like, or the execution unit 3 may get to the instruction unit 5 in response to an event such as an exchange with the ONU. You may go there. This also applies to other use cases, APIs and embodiments.

Further, although the instruction unit 5 shows an example composed of the policy determination unit 103 and the allocation calculation unit 102, the instruction unit 5 is only the policy determination unit 103, and the execution unit 3 further includes the allocation calculation unit 102. It may be configured in. In this case, the DBA-API Set / Get is an allocation calculation parameter and a policy determination parameter, similar to the SR-DBA for mass (partially softened (of the DBA function)) of use case 3 (b) described later. May be good. Further, the cooperation control unit 1011 may be the instruction unit 5. In FIG. 3, the cooperation control unit 1011 is arranged below the DBA-API, but the cooperation control unit 1011 may be a part of the execution unit 3 or a functional unit other than the execution unit 3. It may be a part of the instruction unit 5 that processes the information obtained through the IF different from the API. Further, the input of the cooperation control unit 1011 may be directly output to the grant processing unit 104. The attribution is not limited to the above example.

API of each use case of DBA (optical mobile cooperation DBA for MFH, NSR-DBA for MFH, SR-DBA for mass (full software of DBA function), SR-DBA for mass (partial software of DBA function)) The outline of the above is shown in FIGS. 32A and 32B. The "use cases" column in FIGS. 32A and 32B shows the correspondence between each use case and the API. That is, each API is a use case (optical mobile cooperation DBA for MFH, NSR-DBA for MFH, SR-DBA for mass) with a check mark among "1", "2", "3a", and "3b" of "use case". (Full software of DBA function), SR-DBA for mass (partial software of DBA function)). For example, as shown in FIG. 32A, the API "on_Init" has an input of "none" and an output of "none", and the outline of "on_Init" is a "callback function called at initialization". It has been shown to be used in all use cases. In FIGS. 32A and 32B, an event-driven DBA program is assumed.

The API is a common API set regardless of the DBA FASA application (DBA application) to be added or replaced, and the API to be used in each DBA application is selected from the common API set. For example, API "get_AllocationDbaConfig", "set_GrantSize", "set_GrantSizeAndStartTime" are commonly used in DBA apps, "get_CooperationConfig", "get_DataSize", "get_Traffic", "get_AllocUnitTraffic", "get_AllocUnitTraffic", "get_AlocUnitUse DB" .. The commonly used "get_AllocationDbaConfig" acquires the information required for each DBA application from the response data. The API "set_GrantSize" that does not specify the transmission start time determines the transmission time start time on the FASA platform, and the API "set_GrantSizeAndStartTime" that specifies the transmission start time determines the transmission time start time on the FASA application.

“Allocation target” in FIGS. 32A and 32B indicates a logical path that is the target of bandwidth allocation in DBA. The allocation target number is an index to be allocated. The config number is an index of setting parameters. The monitor number is an index to be measured by the traffic monitor. The policy determination parameter is a parameter used in the calculation of the policy determination unit. The parameter for allocation calculation is a parameter used in the calculation of the allocation calculation unit.

In this use case, for example, the API in which the column of use case 1 is checked in FIGS. 32A and 32B is an example of the API used by the optical mobile cooperation DBA for MFH. For example, the API "get_CooperationConfig" acquires the operation cycle and operation mode of the cooperation control unit 1011, the system name of the cooperation destination, the version, and the like. The API "get_DataSize" is called for each bandwidth allocation. The API "get_DataSize" acquires the allocation targets individually or collectively in the specified range. As shown in FIGS. 32A and 32B, the API "get_DbaConfig" has an input of "config number" and an output of "setting value", and the outline of "get_DbaConfig" is "acquiring DBA config information". It is shown that there is. Here, the config number is an index of the setting parameter. Examples of the config information include a DBA cycle and the like. Here, as illustrated in the DBA cycle, a predetermined allocation trigger may be selected and conditions that serve as the trigger may be selected. Further, the API "set_DbaConfig" has an input of "config number and setting value", an output of "none", and the outline of "set_DbaConfig" is "setting the DBA config information to be assigned". It is shown.

Explaining in the form of setting (get) and reading (set) from the instruction unit 5 to the execution unit 3, for example, when setting the DBA cycle, the instruction unit 5 reads the DBA cycle with the API "get_DbaConfig" and sets "set_DbaConfig". It is used to set the DBA cycle in the execution unit 3. Further, the API "get_coperationIfConfig" is a command for acquiring, for example, the operation cycle, the operation mode, the system name of the cooperation destination, the version, etc. of the cooperation control unit 1011.

The API "get_DataSize" indicates that the input is "time, allocation target ID", the output is "requested amount", and the outline of "get_DataSize" is "acquire the requested amount of the allocated target". Has been done. Here, the allocation target ID is identification information for identifying the allocation target. Further, in the API "set_GrantSize", the input is "allocation target ID, allocation amount", the output is "none", and the outline of "set_GrantSize" is "add the allocation amount for the allocation target to the end of the grant". It is shown to be.

When the API "get_DataSize" is defined individually for each AllocID, the API for the AllocID set at the time of band request is get, and when it is defined in the specified range, the specified AllocID is collectively get. The API "set_GrantSize" that does not specify the transmission start time is the execution unit 3, and the API "set_GrantSizeAndStartTime" that specifies the transmission start time and the API "set_StartTime" that specifies the transmission start time are the execution units 3, respectively. decide.

It is shown that the API "get_DbaConfig" has an input of "config number" and an output of "set value", and the outline of "get_DbaConfig" is "acquire DBA config information".

For example, the process shown in FIG. 33 is performed using the API of the optical mobile cooperation DBA for MFH. FIG. 33 is a system configuration and operation sequence diagram of the optical mobile cooperation DBA for MFH. As shown in FIG. 33, in the optical mobile cooperation DBA for MFH, the bandwidth allocation satisfying the delay regulation of MFH is realized by the cooperation between BBU and OLT. Specifically, instead of the report from the ONU, the band allocation information (upstream band of each ONU, allocation of transmittable time slot) DBA application from the radio resource information corresponding to the uplink transmission control information of each UE generated by the BBU. Alternatively, the bandwidth is allocated by calculating with other FASA boards or external devices. As a method of notifying the radio resource information, a method of calculating at least one of the uplink data amount and the arrival time at which the OLT arrives at each ONU after notifying as a parameter of the mobile system, and the uplink data amount and the arrival time from the BBU are calculated. A method of notifying directly is conceivable. In this DBA, a possible API is required for cooperation with an external device. The above operation is an example and is not limited to this.
In this use case, the optical mobile cooperation DBA for MFH is used, but the same API may be used as a DBA for businesses other than MFH and for mass.

The API is a common API set regardless of the instruction unit for replacing / adding algorithms and the like, and the API to be used in the instruction unit 5 is selected from the common API set. For example, the API "get_AllocationDbaConfig" is commonly used by a plurality of DBAs, and the information required for each DBA is used from the response data. The allocation target ID is AllocID in NG-PON2.

(Use case 2)
In use case 2, as an example, the allocation calculation unit 102 and the policy determination unit 103 are configured as the instruction unit 5, and the grant processing unit 104 is configured as the execution unit 3. The instruction unit 5 acquires the traffic amount from the execution unit 3 (DBA-API Get) and outputs it to the execution unit 3 (grant processing unit 104) (DBA-API Set). When the DBA-API Set is only the allocation amount, the execution unit 3 allocates the transmission start time to each allocation target and generates grant information such as BWmap. When the DBA-API Set has a transmission start time and an allocation amount, it generates grant information according to the transmission start time and the allocation amount of each allocation target as obtained.

Here, the instruction unit 5 shows an example composed of the policy determination unit 103 and the allocation calculation unit 102, but the instruction unit 5 is only the policy determination unit 103, and the execution unit 3 further includes the allocation calculation unit 102. It may be configured as follows. The DBA-API Set / Get may be an allocation calculation parameter and a policy determination parameter, as in the SR-DBA for mass (partially softened (of the DBA function)) of use case 3 (b) described later. Further, although the configuration in which the traffic monitor 1012 is provided in the execution unit 3 is shown, the traffic monitor 1012 may be provided in a device such as an external switch.

The API in which the column of use case 2 is checked in FIGS. 32A and 32B is an example of the API used by NSR-DBA for MFH. For example, API "get_Traffic" and "get_AllocUnitTraffic" are called for each bandwidth allocation. The API "get_Traffic" mainly measures the flow of multiple OLTs, multiple OSUs, or multiple CTs (Channel Termination), and the API "get_AllocUnitTraffic" mainly measures the entire allocation target or a specific flow of the allocation target. It is shown that the API "get_DbaConfig" has an input of "config number" and an output of "set value", and the outline of "get_DbaConfig" is "acquire DBA config information". Further, the API "set_DbaConfig" has an input of "config number and setting value", an output of "none", and the outline of "set_DbaConfig" is "setting the DBA config information to be assigned". It is shown.

The API "get_Traffic" indicates that the input is a "monitor number", the output is a "monitor result", and the outline of "get_Traffic" is to "acquire the monitor result of the monitor number". .. Here, the monitor number is identification information for identifying the monitored object. Further, in the API "set_GrantSize", the input is "allocation target ID, allocation amount", the output is "none", and the outline of "set_GrantSize" is "add the allocation amount for the allocation target to the end of the grant". It is shown to be.

Further, the measurement units of the APIs "get_Traffic" and "get_AllocIdTraffic" are arbitrarily set with a particle size from a specific flow of AllocID to the total value of a plurality of ONUs. Mainly, API "get_Traffic", for example, a unit not for each AllocID such as the whole OLT, the whole OSU (Optical Subscriber Unit), the whole CT, and "get_AllocIdTraffic" is a unit below AllocID. "Set_TrafficMonitorConfig" or the like may be set as an API for setting the particle size of the input parameters (monitor unit) of "get_Traffic" and "get_AllocIdTraffic". The same applies to get_Report, get_AllocIdReportTraffic, get_TimeDataSize, get_DataSize and the like.

It is shown that the API "get_DbaConfig" has an input of "config number" and an output of "set value", and the outline of "get_DbaConfig" is "acquire DBA config information".
Using the API of NSR-DBA for MFH described above, for example, the processes of FIGS. 34 and 35 are performed. 34 and 35 are diagrams showing an operation example of NSR-DBA for MFH by API. 34 and 35 show an outline of two types of NSR-DBA for MFH. These use NSR-DBA based on fixed bandwidth allocation (FBA) to reduce the round-trip delay of the control signal generated by SR-DBA, and realize bandwidth allocation that meets the delay regulation of MFH. Specifically, by applying NSR-DBA based on traffic statistical data, it is possible to improve the efficiency of the entire system such as sharing with a mass-oriented system while reducing the excessive allocated bandwidth generated by FBA.

The first NSR-DBA (FIG. 34) estimates the TDD period of a TDD-type mobile system and allocates bandwidth according to the TDD period. This DBA requires an API that uses traffic statistics at a sampling rate at which the TDD period can be estimated.
The second NSR-DBA (Fig. 35) focuses on the fact that the fluctuation of traffic is periodic when observed on the time axis of about 1 day to 1 week, and the following is based on the traffic statistics in FBA. Estimate and allocate the required bandwidth for the traffic cycle of. This DBA requires an API that uses long-term traffic statistics.
The above operation is an example and is not limited to this. In this use case, NSR-DBA for MFH is used, but the same API may be used as DBA for businesses and masses other than MFH.

(Use case 3)
In the use case 3, as an example, the allocation calculation unit 102 and the policy determination unit 103 are configured as the instruction unit 5, and the grant processing unit 104 is configured as the execution unit 3. The instruction unit 5 acquires the requested amount from the execution unit 3 (DBA-API Get) and outputs it to the execution unit 3 (grant processing unit 104) (DBA-API Set). When the DBA-API Set is only the allocation amount, the execution unit 3 allocates the transmission start time to each allocation target and generates grant information such as BWmap. When the DBA-API Set has a transmission start time and an allocation amount, it generates grant information according to the transmission start time and the allocation amount of each allocation target as obtained.

An example of SR-DBA for mass (in the case of full software (in the case of DBA function)) and SR-DBA for mass (in the case of partial software (in the case of DBA function)) for mass is shown. An API with a check mark in the column of use case 3a in FIGS. 32A and 32B is an example of an API used in SR-DBA for mass (full software of DBA function). For example, the API "get_ReportSize" is called for each bandwidth allocation. API "get_ReportSize" is to acquire the value of either individual or the allocation target of the specified range.

It is shown that the API "get_DbaConfig" has an input of "config number" and an output of "set value", and the outline of "get_DbaConfig" is "acquire DBA config information". Further, the API "set_DbaConfig" has an input of "config number and setting value", an output of "none", and the outline of "set_DbaConfig" is "setting the DBA config information to be assigned". It is shown. The "config information of the allocation calculation unit" of the "get_CalcConfig" of the API represents, for example, setting information such as the maximum bandwidth and the guaranteed bandwidth for each allocation target.

It is shown that the API "get_AllocIdReport" has an input of "assignment target ID", an output of "wint32_t request amount", and an outline of "get_AllocIdReport" is "acquire the request amount of the allocation target". ing. Further, in the API "set_GrantSize", the input is "allocation target ID, allocation amount", the output is "none", and the outline of "set_GrantSize" is "add the allocation amount for the allocation target to the end of the grant". It is shown to be.

It is shown that the API "get_DbaConfig" has an input of "config number" and an output of "set value", and the outline of "get_DbaConfig" is "acquire DBA config information".

Further, the API in which the check is checked in the column of use case 3b in FIGS. 32A and 32B is an example of the API used in SR-DBA for mass (partially softened DBA function). The "config information of the allocation calculation unit" of the API "get_CalcConfig" is, for example, setting information such as the maximum bandwidth and the guaranteed bandwidth for each allocation target. The "policy determination parameter" is the history of the requested amount and the allocated amount.

It is shown that the API "get_DbaConfig" has an input of "config number" and an output of "set value", and the outline of "get_DbaConfig" is "acquire DBA config information". Further, the API "set_DbaConfig" has an input of "config number and setting value", an output of "none", and the outline of "set_DbaConfig" is "setting the DBA config information to be assigned". It is shown.

The API "get_ParameterForPolicyMaking" has an input of "policy determination parameter number", an output of "policy determination parameter value", and an outline of "get_ParameterForPolicyMaking" is "acquire the value of the parameter number". It is shown. In addition, the API "set_ParameterForCalc" has an input of "policy determination parameter number, allocation calculation parameter" and an output of "none", and the outline of "set_ParameterForCalc" is "set the value of the parameter number". It is shown to be. The API "parameter for policy determination" is the history of the requested amount and the allocated amount.
It is shown that the API "get_DbaConfig" has an input of "config number" and an output of "set value", and the outline of "get_DbaConfig" is "acquire DBA config information".

Using the API of SR-DBA for mass (full software (of DBA function) and partial software (partial software of DBA function)), bandwidth allocation that satisfies the requirements of SR-DBA for mass is performed. In SR-DBA for mass, bandwidth is dynamically allocated to each ONU based on the requested amount extracted from the declaration of each ONU. Therefore, in this DBA, an API that extracts the required amount from the declaration of each ONU is required.
The requirements for SR-DBA for mass are shown below.
-Bandwidth utilization efficiency (ratio of SNI output band to PON band * 1): x% or more-UNI-SNI delay (highest priority class * 2): within 1500 microseconds * 3
-Bandwidth fairness (ratio of actual allocated bandwidth to ideal allocated bandwidth * 4): within y% -Delay fairness (difference in average delay between users of the same service): within z% -Priority control: During congestion Only low-priority frames other than the highest-priority class * 2 are discarded * 1: Data bandwidth of the PON section excluding overhead * 2: Total of the highest-priority class flow bandwidths of all ONUs ≤ PON bandwidth * 3: ITU-T G.989.3
* 4: For example, MaxMin fairness

The above requirements are examples and may vary from service to service or from carrier to carrier. This DBA requires an API that can handle the addition and replacement of required conditions.
In addition, this DBA also defines an API for mounting a part of processing on dedicated hardware such as a PON MAC chip from the viewpoint of processing performance and the like. As a specific process, a process as described later may be used.
The above operation is an example and is not limited to this.
In this use case, SR-DBA for mass is used, but the same API may be used as DBA for businesses other than mass and for MFH.

In the above use case, the examples are given separately for MFH and mass, but allocation targets such as ONU, OLT, Alloc-ID, and MLID for MFH and mass may be mixed, and the same allocation target may be used. , Cooperation and NSR and SR may be mixed. The mixture may be coexistence, combination, or switching over time. As for API, at least API to be used may be prepared. For example, Alloc-ID1-5 is for MFH optical mobile cooperation DBA, Alloc-ID6-10 is for mass NSR-DBA, and Alloc-ID10-15 is for MFH optical mobile cooperation DBA and mass. NSR-DBA may be switched, and Alloc-ID15-20 may be used in combination with NSR-DBA and SR-DBA for mass. In this case, all APIs used in any Allloc-ID may be provided for all Alloc-IDs, or APIs required for each Alloc-ID may be provided for each API.

As shown in the above use case, the execution unit 3 includes, for example, a grant processing unit 104, and the grant processing unit 104 may generate a BWmap or the like, or generate a frame instructing the ONU to generate a BWmap. You may even go to the process of doing.
The execution unit 3 may include, for example, a declaration receiving unit, and the grant processing unit 104 may perform processing such as integration of declaration information or processing up to reading from an uplink frame such as DBRu.
The execution unit 3 includes, for example, a traffic monitor 1012, and the traffic monitor 1012 may perform processing such as integration of monitor information, or may perform up to the monitor.

As for the generation of BWmap or the like, for example, iterative allocation is performed to the same destination with a predetermined band or a predetermined band setting.
The instruction unit 5 instructs the execution unit 3 so that the allocation of the execution unit 3 approaches a desired state according to the service policy that differs depending on the telecommunications carrier and the service. For example, the allocation information in the execution unit 3 is detected, and the allocation in the execution unit 3, the allocation result, the allocation history, the data continuity associated with the allocation, the continuity history, the request, and the request so as to be the detection result and the desired allocation. The history, the history of the information from the external device, and the history of the information from the external device are detected, and one of the following (a) to (e) is instructed to the execution unit 3 so that the detection result approaches the desired allocation.

You can change algorithms and policies. In this embodiment, as long as it is not necessary to change, the allocation is continued with the same predetermined band or band setting for each destination after a lapse of time. "Continue" will continue unless instructed to change it. The minimum time to continue is equal to or greater than the sum of the time required for the execution unit 3 to respond to the instruction, the time required for the instruction unit 5 to create the instruction, and the communication time between the instruction unit 5 and the execution unit 3. It is desirable that the instruction from the instruction unit 5 and the response of the execution unit 3 have the same period or a period proportional to an integral multiple or a fraction of an integer and be synchronized, but at least a part of the history such as the exponential average is continuously detected. If is used, the cycles may be asynchronous even if they are not in a multiple relationship. The cycle may be a cycle related to the allocation of DBA, DWA, DWBA, etc., or may be a cycle in which the allocation to the allocation target at least required or predicted to be required is completed.

The allocation information in the execution unit 3 is the allocation or allocation result in the execution unit 3, the allocation history, the data continuity or continuity history associated with the allocation, the request or request history, the information from the external device, or the history of the information from the external device. Includes at least one. "Request" means a request for upstream band / transmission time or a prediction thereof in the ONU declaration. A part or all of the request, the request history, the information from the external device, or the history of the information from the external device may be processed or held by the execution unit 3, or part or all may be processed by the instruction unit 5.

At least a part of the prediction of the request may be carried out by the execution unit 3 or the instruction unit 5 or other parts, and at the place where the request is executed, the allocation or allocation result or allocation history or data continuity or continuity history or request or request may be performed. It is desirable to receive input of information necessary for prediction such as history or information from an external device or history of information from the external device.

The data continuity is the execution unit 3, the instruction unit 5, and other parts such as the switch unit (SW) 12, the switch unit (SW) 13, the proxy unit 15, and the network of the main signal or the control signal, which will be described later, in which the main signal is conducted. It may be detected by any of the higher-level devices.

(Embodiment 1.1)
In this embodiment, the band allocation by time division multiplexing in one wavelength of TWDM-PON is mainly illustrated, but time division multiplexing, wavelength division multiplexing, core line division multiplexing, core division multiplexing, mode division multiplexing, and code. It may be assigned in at least one combination of other division multiplexing such as division multiplexing and (orthogonal) frequency division multiplexing. In this case, the same applies if the sum of other division multiplexing such as wavelength, core wire, core, mode, sign and (orthogonal) frequency to be divided and multiplexed is assigned. For example, 40 Gbit / s for 4 wavelengths of 10 Gbit / s / λ, 30 Gbit / s for 1 core of 10 Gbit / s and 1 core of 20 Gbit / s, and 4 wavelengths of 10 Gbit / s / λ. If it is a 2-core wire, 80 Gbit / s may be allocated, and the instruction may be a combination of the assigned ones. Here, the allocation is one of the allocated band, wavelength, core, core, mode, sign and (orthogonal) frequency, or the allocated band, wavelength, core, core, mode, depending on the object to be allocated. It may be either one of the allocated bands for each sign and (orthogonal) frequency, or one of the allocated bands of the sum of them.

The execution unit 3 of the present embodiment continues to allocate to the same destination with any one of a predetermined band, wavelength, core wire, core, mode, code, and (orthogonal) frequency, or at least any combination thereof. The instruction unit 5 of the present embodiment detects the allocation, allocation result, allocation history, data continuity associated with the allocation, continuity history, request, request history, information from the external device, and history of information from the external device of the execution unit 3. Then, the execution unit 3 is instructed to suppress the allocation or preferential allocation to at least a part of the allocation target so that the detection result of the predetermined period and the desired allocation can be obtained.

On average, the predetermined band is allocated (for example, ONU, ONU queue, ONU class buffer, Alloc-ID (Allocation Identifier), T-CONT (Transmission Container) and LLID (Logical Link ID (IDentifier)). ) Etc.) If there is a fixed band setting for each, the fixed band setting value is set as the lower limit, if there is a maximum band setting, the maximum band setting value is used, or if there is a total band that can be used by multiple allocation targets, the total band is used. It is desirable to set the value of, or the lower limit of both, if any, as the upper limit.

The predetermined band includes a single or multiple BWMap forms, allocation time for each allocation unit such as T-CONT, Alloc-ID, LLID, combination of start time and allocation time, T-CONT, Alloc-ID, LLID, etc. The bandwidth may be a combination of the allocation time and the allocation order for each allocation unit.

It is desirable that the predetermined period is longer than the time required for the execution unit 3 to change the predetermined band in response to the instruction of the instruction unit 5. For example, it is several to a dozen times, and it is the time required for multiple changes. Further, it is desirable that the time is such that the user does not detect the difference from the desired allocation. For example, it is desirable that the time unit for measuring the band, for example, 1 second or less.

The allocation or allocation result of the execution unit 3 is the OAM or the history of the retained information or the past instruction for the declaration from the execution unit 3 or the measurement at any place or the declaration to the upper system on the control side such as the operation system. Input via the backboard, internal wiring, main signal wiring, dedicated wiring, operating system, controller, control unit, or other route, or input from the history of instructions held by the instruction unit 5. The history may be integrated by a device other than the indicator unit 5.

The allocation history for a predetermined period is, for example, an exponential average, a moving average, an average in which the history is reset at a predetermined interval, and a history of other statistical processing.

As for the data continuity or continuity history associated with the allocation, the internal wiring, backboard, OAM, and main hold information for measurement at any point such as the declaration from the execution unit 3 or the path of the main signal or the declaration to the host system. Input via signal lines, dedicated wiring, operating systems, controllers, control units, and other routes. The history may be integrated by a device other than the indicator unit 5.

For the request, request history, information from the external device, and history of information from the external device, the declaration from the ONU or the copy of the declaration is directly terminated by the instruction unit 5 and input, or terminated at any location and used for internal wiring. Use of input or allocated band via the backboard, OAM, main signal line, dedicated wiring, operating system, controller, control unit, etc. (If there is unused allocation, use is requested, unused allocation If there is no (if it is fully used), the request from the execution unit 3 or the measurement at any location or the retention information for reporting to the host system or the history of past instructions is internally wired or backed up. Input via a board, OAM, main signal line, dedicated wiring, operation system, controller, control unit, or other route, or input from the history of instructions held by the instruction unit 5. The history may be integrated by a device other than the indicator unit 5.

Requests, request history, information from external devices and history of information from external devices are input allocation, allocation history, data continuity, continuity history, allocation results and requests, request history, information from external devices and from external devices. From the history of the information of, the future request or the band that should have been originally allocated but not allocated may be predicted. The prediction may be made by statistical processing such as a linear function, a quadratic function, an exponential average, or a moving average, or RTT (Round Trip) set according to the past request, the result of allocation use, the distance to the server, and the like. It may be predicted based on the behavior of TCP (Transmission Control Protocol) based on Time) etc., it may be predicted that it is a guaranteed bandwidth setting if there is no unused allocation, and it may be predicted that it is a guaranteed bandwidth setting if there is no unused allocation. Is non-zero or the value obtained by subtracting the fixed band setting from the guaranteed band setting is non-zero and there is no unused allocation or the non-guaranteed band is set as the guaranteed band or the guaranteed band setting for the allocation target that exceeds the guaranteed band setting and is requested. It may be predicted that the bandwidth is proportionally divided according to the value obtained by subtracting the fixed bandwidth setting from, or if there is no unused allocation, there is no unused allocation, or the guaranteed bandwidth setting is exceeded and the best effort bandwidth is requested. May be predicted as a proportionally divided band. Moreover, you may make a prediction by combining a plurality of prediction methods.

The desired allocation is made according to a predetermined ratio, with the upper limit being the bandwidth obtained by adding the bandwidth for detecting the deviation from the requirement or the predicted value of the requirement or the requirement or the predicted value of the requirement to the allocation target with the request. Bandwidth is fine. The predetermined ratio is, for example, the ratio of the guaranteed band setting or the value obtained by subtracting the fixed band setting from the guaranteed band setting. The predetermined band may be any of wavelengths, codes, carrier frequencies, cores, cores, modes, codes and (orthogonal) frequencies, or at least some combinations thereof, or to them. It may be set in units of corresponding TRx (Transmitter and Receiver), Tx (Transmitter), Rx (Receiver), or multiple wavelengths, codes, carrier frequencies, core lines, cores, modes, codes, and (orthogonal). ) It may be set in OSU units in which TRx, Tx and Rx are bundled, such as any of each frequency or at least a combination thereof, or in SW (Switch) units in OSU, or a plurality of wavelengths and codes. , Carrier frequency, core line, core, mode, sign, (orthogonal) frequency, or at least a part of them, TRx, Tx, Rx, or OSU bundled in SW unit. Alternatively, it may be set in units of allocation targets that share the bandwidth of the upper device. It is desirable that the desired allocation is limited to the maximum bandwidth setting for each allocation unit, and if there is a total bandwidth setting such as TRx, Tx, Rx, or a bundle thereof, it is desirable to use it as the upper limit.

The method of approaching the desired allocation for a predetermined period is arbitrary, and the following can be exemplified.
The execution unit 3 continues the allocation with a predetermined setting or band. The instruction unit 5 has no allocation deterrence or preferential allocation suspension or no allocation deterrence or preferential allocation for the allocation target whose allocation exceeds the desired allocation to the execution unit 3, and preferential allocation or allocation deterrence for the insufficient allocation target. Indicates at least one of suspension or deterrence of allocation and no preferential allocation. Here, the instruction of priority allocation, allocation suppression, priority allocation suspension, or allocation suppression suspension is given when the state before the instruction is reversed, or if it is excessive, it is instructed by the insufficient side, and if it is insufficient, it is instructed by the excess side. This is the case when the relevant side does not have to give instructions. The allocation suppression and priority allocation bands may be explicitly instructed by the instruction unit 5, or some of the particle sizes may be instructed at a predetermined particle size, and the instruction unit 5 may specify only the allocation suppression and the priority allocation. Only, allocation deterrence and priority allocation only, allocation deterrence and priority allocation and allocation deterrence and no priority allocation, allocation deterrence suspension and priority allocation suspension, etc. may be instructed.

Further, the suppression may completely suppress the allocation of the allocation target and set it to zero, and the priority may allocate all the allottable bands to the allocation target. As for the instruction to the execution unit 3, if the allocation target is ONU1 to 3, for example, a mark, for example, "1" is given only to the allocation suppression target, and no mark is given to the non-allocation suppression target, for example, "0" remains. If only ONU1 is suppressed, the instruction corresponds to (ONU1, ONU2, ONU3) = (1, 0, 0). If only the priority allocation target is marked, for example, "1", and the allocation suppression target is not marked, for example, "0" is left, and only ONU1 is suppressed, (ONU1, ONU2, ONU3) = (1, Instruct corresponding to 0,0). Mark only the targets of priority allocation and deterrence of allocation, for example, "1" and "2" respectively, leave no mark outside the target of deterrence of allocation, for example, leave "0", and ONU1 and ONU2 are prioritized and deterred, respectively. If there is, it is instructed corresponding to (ONU1, ONU2, ONU3) = (1, 2, 0). It may be instructed by the ONU number of the priority or suppression target. Moreover, not only the priority or suppression but also the capacity itself to be prioritized or suppressed, or the band or the set band may be listed. For example, it may be instructed corresponding to (ONU1, ONU2, ONU3) = (20, -10, 0), assuming that ONU1 corresponds to priority 20 Mbit / s and ONU2 corresponds to suppression 10 Mbit / s.

As an example of flexible allocation, when the allocation ratio of the execution unit 3 is fixed to ONU1 to 3 evenly and the desired allocation ratio is 1: 2: 3, for example, the instruction unit 5 sets the ratio of the ONU to the ONU. Only the ratio of the period divided by the sum of the ratios is given complete priority, and the other periods are completely suppressed. A 1: 2: 3 allocation ratio can be obtained by combining complete priority and complete deterrence so that the ratio of the period of complete priority is 1/6, 2/6, and 3/6 for ONU1, 2, and 3, respectively.

An example of the priority allocation and allocation suppression values set in the execution unit 3 or instructed from the instruction unit 5 is shown.

-A single or multiple predetermined periods are allocated and suppressed with the fixed bandwidth setting as the lower limit so that the difference between the allocation target with a high allocation history for a predetermined period from the predicted or desired allocation with a request or a request is eliminated.
-A single or multiple predetermined period allocation is suppressed so as to eliminate the difference between the allocation target that is predicted to have a request or a request and has a high allocation history for a predetermined period from the desired allocation.
-Priority allocation or deterrence is made so that the allocation target with a high or low allocation history for a predetermined period from the prediction of request or request and the desired allocation has the guaranteed bandwidth setting or fixed bandwidth setting of the allocation target.
-For the allocation target with a high or low allocation history for a predetermined period from the prediction of request or requirement and the desired allocation, the non-guaranteed allocation band or best effort band or its predicted value is assigned to the guaranteed band setting of the allocation target. Priority allocation or suppression of allocation shall be applied to bands that are less than the band proportionally divided according to the above.
-Priority allocation or deterrence of allocation so that the allocation target of the prediction of no request or no request becomes the guaranteed band setting or fixed band setting of the allocation target.
-Although the allocation suppression or priority allocation is illustrated by the instruction to the allocation itself, the request is added or subtracted, multiplied by a predetermined ratio, or when the execution unit 3 holds the history, the history is added or subtracted by the addition, subtraction, multiplication, or division.

The transmission from the instruction unit 5 to the execution unit 3 may be transmitted by assigning an identifier such as a predetermined bit string so as to be distinguishable from other information, or may be transmitted in the form of an embedded OAM. , OAM frame, MPCP (Multi Point Control Protocol) frame, predetermined VID (VLAN (Virtual Local Area Network) Identifier), MAC address, TOS / COS (Type of Service / Class of Service), their combination, and VPI. It may be encapsulated in a frame or cell that can be identified by (Virtual Path Identification) or VCI (Virtual Channel Identification) and exchanged. The instruction unit 5 has a function of assigning an identifier, encapsulating it, and communicating on a predetermined communication path so that the processing unit can identify it, and the processing unit identifies and decapsulates the identifier and communicates on a predetermined communication path so that it can be identified. It has a function to receive. The input / output from the processing unit to the instruction unit 5 is the same, and the declaration is exchanged with the function of processing the declaration from the ONU so that it can be received and inputting it to the instruction unit 5 except when the instruction unit 5 directly terminates the declaration. Prepare for the route, etc.

(Embodiment 1.2)
The execution unit 3 of the present embodiment assigns to the same destination by setting any one of a predetermined band, wavelength, core wire, core, mode, code, and (orthogonal) frequency, or at least one combination thereof. continue. The instruction unit 5 of the present embodiment instructs the execution unit 3 to change the band setting so that the detection result of the predetermined period and the desired allocation are obtained.

The method of approaching the desired allocation for a predetermined period is arbitrary, and the following can be exemplified.
The execution unit 3 continues the allocation with the predetermined settings. The instruction unit 5 instructs the execution unit 3 to decrease the set value for the allocation target whose allocation exceeds the desired value and increase the set value for the insufficient allocation target. The set value may be explicitly instructed from the instruction unit 5, or may be instructed by a certain amount of the particle size at a predetermined particle size, and the instruction unit 5 may increase or decrease the set value and return to the initial setting. You may instruct. The instruction to the execution unit 3 is a part or all specific values such as ONU1 to 3, fixed band, guaranteed band, and maximum band set values P_FXBi, P_GUBi, and P_MABi (i = 1 to 3). The value corresponding to may be specified, the increase / decrease value of the corresponding set value may be specified, or other set values may be specified.

As an example of flexible allocation, it is possible to provide a new service with an upper limit set for the bandwidth used for a predetermined period on an existing device, but when the upper limit is reached by the instruction unit 5, the execution unit changes the set value. It can be realized without changing the execution unit 3 by instructing in 3.

An example of the value of the setting or the setting change instructed from the instruction unit 5 to the execution unit 3 is shown.

(Embodiment 1.3)
Execution unit 3 of the present embodiment continues to allocate to the same destination in a predetermined band or wavelength or core wire or core or mode or code or (orthogonal) frequency or at least a combination thereof. The instruction unit 5 of the present embodiment instructs the execution unit 3 to make a predetermined allocation so that the detection result of the predetermined period and the desired allocation can be obtained.

The method of approaching the desired allocation for a predetermined period is arbitrary, and the following can be exemplified.
The execution unit 3 continues the allocation with the allocation instructed by the instruction unit 5. The instruction unit 5 instructs the execution unit 3 to allocate at least one of a decrease in the allocation of the allocation target in which the allocation exceeds the desired value and an increase in the allocation to the insufficient allocation target. The instruction may be an allocated band in a predetermined cycle for each allocation target, may be an Alloc-ID specified by BWMap, and may be a time slot to be allocated corresponding to the Alloc-ID, or may be a predetermined period. It may be the transmission start time and the transmission continuation time for each allocation target in. The instruction may be in a format that can be assigned to the allocation target by the execution unit 3. The predetermined period may be one or more BWMaps, one or more DBA cycles, or BWMaps or DBA cycles other than integer multiples if convertible. .. The time to change to the new allocation from the instruction unit 5 of the execution unit 3 is preferably the timing when the allocation has run its course, but it may be as soon as the new allocation arrives.
Flexible allocation is possible by changing the allocation instructed by the instruction unit 5 without changing the execution unit 3.

An example of the value of the allocation set in the execution unit 3 or instructed by the instruction unit 5 is shown.
-Add the band obtained by dividing the difference by a single or a plurality of predetermined periods to the allocation target having a low allocation history for a predetermined period from the predicted or desired allocation with a request or a request, up to the maximum band setting.

(Embodiment 1.4)
Execution unit 3 of the present embodiment continues allocation to the same destination by setting a predetermined band or wavelength or core wire or core or mode or code or (orthogonal) frequency or at least one combination thereof. The instruction unit 5 of the present embodiment instructs the execution unit 3 in the order of allocation so as to obtain the detection result and the desired allocation.

The method of approaching the desired allocation for a predetermined period is arbitrary, and the following can be exemplified.
The execution unit 3 allocates a large band according to the order of allocation. For example, the allocation order allocates all to the first allocation target, allocates the request or request prediction to the first allocation target up to the upper limit, and continues the allocation to the allocation target in the later order. In the case of this example, the order in front is the order in which the allocation is large, and the order in the rear is the order in which the allocation is small. In the opposite case, the opposite is true. The allocation order of the execution unit 3 may be the same every time if there is no instruction from the instruction unit 5. The order may be changed so as to shift and circulate by moving up or down the order for each one or a plurality of allocations. In the instruction unit 5, the allocation in the execution unit 3 is in the smaller order for the allocation target whose allocation exceeds the desired allocation to the execution unit 3, or the allocation in the execution unit 3 is made for the insufficient allocation target. You can get closer to the desired allocation by instructing at least one of the larger orders. When moving up, down, or shifting the order for each allocation, it is particularly desirable to arrange the allocation order in descending order of the difference between the detection result and the desired allocation. It is desirable to change the allocation order for each allocation cycle or for each allocation cycle for the number of allocation targets for which the request or request prediction is non-zero, but other than that if the process of continuously detecting at least a part of the history such as the exponential average is used. It may be out of phase of the period.

As an example of flexible allocation, the allocation order in which the allocation order of the execution unit 3 is equal in ONU1 to 3, for example, 1-> 2-> 3-> 1-> ... When the desired allocation ratio is 1: 2: 3, for example, the indicating unit 5 may allocate a large band by the ratio of the ONU. For example, a 1: 2: 3 allocation ratio can be obtained by setting 1-> 2-> 2-> 3-> 3-> 3-> ....

An example of the allocation order instructed by the instruction unit 5 to the execution unit 3 that allocates a larger band in the order of the front is shown. If the instruction is given to the execution unit 3 that allocates a larger band in descending order, the front and back of the following example are reversed.
-The order of single or multiple predetermined period allocations should be placed earlier so as to eliminate the difference between the allocation target with a low allocation history for a predetermined period from the predicted and desired allocations with or without requirements. ..

(Embodiment 1.5)
The execution unit 3 of the present embodiment has a plurality of assignments or settings in advance to the same destination with a predetermined band or wavelength or core wire or core or mode or code or (orthogonal) frequency or at least one combination thereof. Continue the allocation in that assignment or setting. In the case of allocation, for example, the allocation shown in the first embodiment 1.3 is used, and in the case of the setting, for example, the setting shown in the first embodiment 1.2 is used. The instruction unit 5 of the present embodiment instructs the execution unit 3 to switch the allocation or the setting used for the allocation by the execution unit 3 so as to obtain the detection result of the predetermined period and the desired allocation.

The method of approaching the desired allocation for a predetermined period is arbitrary, and the following can be exemplified.
The execution unit 3 continues the allocation with the allocation or setting instructed by the instruction unit 5. The instruction unit 5 switches to an allocation or setting that is at least one of a smaller allocation for the allocation target whose allocation exceeds the desired allocation target and a larger allocation for the insufficient allocation target for the execution unit 3. Instruct. When changing to a new allocation or setting from the instruction unit 5 of the execution unit 3, the cycle related to the allocation of DBA, DWA, DWBA, etc., and the allocation to the allocation target at least requested or predicted to be required are completed. It is desirable that the time is synchronized with the cycle or the timing when the allocation with the current setting is completed, but the instruction to switch to the new allocation or setting may be as soon as it arrives. In particular, if a process of continuously detecting at least a part of the history such as the exponential average is used, the cycles may be asynchronous even if they are not in a multiple relationship or the like.

As an example of flexible allocation, it is possible to provide a new service with an upper limit set for the bandwidth used for a predetermined period with an existing device. This can be realized without changing the execution unit 3 by instructing the execution unit 3 to change.

(Embodiment 2)
In the present embodiment, at least one of time division multiplexing, wavelength division multiplexing, core division multiplexing, core division multiplexing, mode division multiplexing, code division multiplexing, or (orthogonal) frequency multiplexing is used in combination, and the wavelength used by the allocation target is used. Alternatively, it is exemplified by switching of a core wire or a core or a mode or a sign or a (orthogonal) frequency or at least one of them (hereinafter referred to as a group). These are suitable when the switching of the other division multiplexing is slow with respect to the allocation cycle of the time division multiplexing, and the time division multiplexing and the other division multiplexing are performed separately.

Also in this embodiment, the OLT has a time division multiplexing switching function, and the OLT includes an execution unit 3 and an instruction unit 5. The execution unit 3 mainly performs simple processing. For example, the same allocation target, for example, an ONU, is assigned with a predetermined wavelength or core or core or mode or code or frequency or a predetermined wavelength setting or core setting or core setting or mode setting or code setting or frequency setting. The instruction unit 5 instructs the execution unit 3 so that the processing result of the execution unit 3 approaches the desired allocation according to the service policy that differs depending on the communication carrier or the service. For example, the following (a) to (e) are applied to the execution unit 3 so that the allocation information in the execution unit 3 is detected and the detection result and the desired allocation are obtained so that the allocation in the execution unit 3 approaches the desired allocation. ) Is instructed.

Next, within the switching of a band or a wavelength or a core wire or a core or a mode or a code or a frequency or at least any combination thereof, the wavelength is illustrated. This switching corresponds to DWA if it is a wavelength.

(Embodiment 2.1)
The execution unit 3 of the present embodiment switches the group to be allocated according to a predetermined order. The predetermined order is, for example, that at least some of the allocation units simply change groups sequentially, or switch groups of at least some of the allocation units that belong to a group of light or heavy congestion that exceeds or falls below a predetermined threshold. It is the order to do. The instruction unit 5 of the present embodiment transfers the allocation or allocation result of the execution unit 3, the allocation history, the data continuity or continuity history associated with the allocation, the request or request history, the information from the external device, or the history of the information from the external device. It is detected, and the switching of the allocation target is suppressed or preferentially switched so that the detection result of the predetermined period and the desired allocation are obtained. Specifically, an allocation target with less allocation than the desired bandwidth suppresses or skips switching to a group of heavy congestion with less available bandwidth when the allocation target switches, or light with more available bandwidth. The instruction unit 5 is instructed to give priority to switching to the congestion group or suppress the switching itself to reduce the non-allocation period. Allocation targets with more allocation than the desired bandwidth prioritize switching to a group of heavy congestion with less available bandwidth, or deter, skip, or prioritize switching to a group of light congestion with more available bandwidth. Instruct the instruction unit 5 to increase the unassignable period due to the switching.

(Embodiment 2.2)
The execution unit 3 of the present embodiment switches the group to be allocated according to a predetermined order. The instruction unit 5 of the present embodiment detects the allocation or allocation result of the execution unit 3, the allocation history, the data continuity or continuity history associated with the allocation, the request or request history, the information from the external device, or the history of the information from the external device. Then, the execution unit 3 is instructed to change the switching setting so that the detection result of the predetermined period and the desired allocation are obtained. Specifically, the instruction unit 5 is set to increase the frequency of switching to the heavy congestion group, the time belonging to the heavy congestion group, and the number of times of switching for the allocation target whose allocation exceeds the desired value for the execution unit 3. The value is set to increase the frequency of switching to the light congestion group, the time belonging to the light congestion group, or decrease the number of switching itself for the insufficient allocation target.

(Embodiment 2.3)
The execution unit 3 of the present embodiment continues the allocation with the allocation instructed by the instruction unit 5, or switches the group according to a predetermined order. The instruction unit 5 of the present embodiment transfers the allocation or allocation result of the execution unit 3, the allocation history, the data continuity or continuity history associated with the allocation, the request or request history, the information from the external device, or the history of the information from the external device. The detection is performed, and the execution unit 3 is instructed to switch the allocation target so that the detection result for a predetermined period and the desired allocation are obtained. Specifically, the instruction unit 5 switches to at least one of a decrease in the allocation of the allocation target whose allocation exceeds the desired value for the execution unit 3 and an increase in the allocation for the insufficient allocation target. Instruct.

(Embodiment 2.4)
The execution unit 3 of the present embodiment continues the allocation with the allocation instructed by the instruction unit 5, or switches the group to be allocated according to a predetermined order. The instruction unit 5 of the present embodiment instructs the execution unit 3 in the order of switching so that the detection result and the desired allocated band are obtained. Specifically, for the allocation target with less allocation than the desired band, the order of switching to the heavy congestion group is advanced or the switching to the light congestion group is advanced or the switching itself is advanced, and the allocation itself is delayed from the desired band. The allocation target with a large number of allocations indicates the order in which the switching to the heavy congestion group is advanced or the switching to the light congestion group is delayed or the switching itself is advanced.

(Embodiment 2.5)
The execution unit 3 of the present embodiment switches the combination or switching setting of the group to be allocated in any of a plurality of predetermined orders or settings. The instruction unit 5 switches to at least one of the following, that is, the allocation is smaller for the allocation target whose allocation exceeds the desired allocation target for the execution unit 3, and the allocation is larger for the insufficient allocation target. To instruct. For example, in the case of switching between two wavelengths 1 and 2 for ONU1 to 3, a combination of wavelength 1 for ONU1 and 2 and wavelength 2 for ONU3 and a combination of wavelength 1 for ONU1 and wavelength 2 and wavelength 2 for ONU2 and 3 are switched. Therefore, the band allocation of ONU1 and 3 is set to a value according to a predetermined ratio. For example, if ONU1 to 3 switch between two wavelengths 1 and 2, and the switching setting is switched, ONU1 and 2 switch the combination of wavelength 1 and ONU3 the wavelength 2 and ONU1 switches the combination of wavelength 1 and ONU2 and 3 the wavelength 2. Then, the band allocation of ONU1 and 3 is set to a value according to a predetermined ratio.

The following is an example of a selection that approaches the desired allocation.
Group ONUs with a large time product of band allocation among the allocation targets belonging to the more heavily congested group (ONU or ONU queue or ONU class buffer, etc., hereinafter represented by ONU) to the light congestion group. In order to stop communication of at least some of the groups when the traffic of multiple groups is predicted to be below or below a predetermined threshold, the ONU belonging to the group is regrouped or suspended to another group. When it is determined to suspend a group to which an active ONU does not belong, or when it is predicted that the traffic of one or more groups exceeds or exceeds a predetermined threshold, communication of at least a part of the groups is started and the ONU belonging to the group is started. The instruction unit 5 makes a determination such as a determination to activate the ONU that has been suspended or the group is changed to the started group, and the execution unit 3 performs the group change according to the instruction based on the determination. Alternatively, the execution unit 3 is regrouped according to a predetermined cycle or opportunity, and the group of the execution unit 3 is regrouped so as to obtain a desired allocation based on criteria such as fairness.

Here, the term “heavy congestion” means that the available band is small for the allocation target, and the wavelength or the like that accommodates a large number of allocation targets with many demands, or the wavelength that the band itself that can be transmitted is originally smaller than the others.

[1] First operation In the first operation, an ONU having a large allocation time product among ONUs belonging to a more heavily congested group is regrouped into a lightly congested group. Among the ONUs belonging to the heavy congestion group, the ONU having a large allocation time product is, for example, an ONU having a large allocation time product as compared with other ONUs belonging to the same group. An ONU having a larger allocation time product than other ONUs is, for example, an ONU having the largest allocation time product in a group, or a predetermined number of ONUs in a group in descending order of allocation time product. It is an ONU with an allocation time product larger than the average value of the allocation time products for all the ONUs to which it belongs or a predetermined value. The predetermined value is, for example, a value obtained by dividing the sum of the time products of the bands of all groups at a predetermined time, for example, the observation time by the total number of ONUs or active ONUs of all groups or the number of ONUs for which the request is unsatisfied. It should be noted that, among the ONUs belonging to the heavy congestion group, which will be described later, among the ONUs belonging to the transmitter / receiver and the heavy congestion group, the product of the time belonging to the heavy congestion group is larger than that of the other ONUs belonging to the group. The number of communication interruptions due to group change compared to other ONUs belonging to the group among ONUs belonging to the light congestion group and ONUs belonging to the heavy congestion group, which have a smaller product of time belonging to the light congestion group than other ONUs belonging to the group. The same applies to the ONU in which the time product of communication interruption due to the group change is small. Here, the congestion of the group is defined as any of the following or a combination thereof.

(1) Number of accommodated ONUs for each group: The larger the number of accommodated ONUs, the heavier the congestion. Congestion (3) Number of ONUs whose allocation does not meet the requirements in the accommodation ONUs for each group: The larger the number of ONUs whose allocation does not meet the requirements in the accommodation ONUs, the more severe congestion (4) The sum of the requests of all ONUs accommodated in each group or Average value: The larger the total or average value of the requests of all ONUs to be accommodated, the more severe the congestion. If the value of is smaller, it is treated as heavy congestion, and if the value is larger, the inverse of them is used. The smaller the total or average value of the allocation of ONUs whose allocation does not meet the requirements for all ONUs, the more heavily congested, and the larger the value, the more heavily congested. The value of the allocation of the maximum ONU: The smaller the value of the allocation of the ONU with the largest allocation in the ONU to be accommodated, the more heavily congested, and the larger the value, the more heavily congested. The allocation value of the ONU whose allocation does not wait for the request in the ONU: The value of the allocation of the ONU whose allocation is the largest in the ONU: The value of the allocation of the ONU whose allocation is the maximum in the ONU which is accommodated does not wait for the request. When treating it as heavy congestion, use the inverse of them. (9) The value of the allocation of the ONU with the smallest allocation in the accommodated ONU for each group: The smaller the value of the allocation of the ONU with the smallest allocation in the accommodated ONU, the more heavy congestion, If the larger value is treated as heavy congestion, use the inverse of them. (10) The ONU accommodated in each group does not wait for the allocation. The ONU allocation value is the smallest. It is an ONU that does not wait and the allocation is the smallest. The smaller the allocation value of the ONU, the more heavy congestion, and the larger the value, the more heavy congestion is used. , The time product belonging to the heavy congestion group is large, the time product belonging to the light congestion group is small, the allocation is small, the time product of communication interruption due to group change is large, or the time product due to group change is large. The greater the number of ONUs that have many communication interruptions, the greater the congestion.

It should be noted that a value of more than a predetermined value may be regarded as heavy congestion, and a value of less than a predetermined value may be regarded as light congestion. The predetermined value is, for example, the value obtained by dividing the number of accommodated ONUs of all groups by the number of groups in (1), or the value rounded up or down, and the number of active ONUs of all groups divided by the number of groups in (2). The value, or the value rounded up or down, the value obtained by dividing the number of ONUs for which the allocation of all groups does not meet the requirement by the number of groups in (3), or the value rounded up or down, all in (4). The sum or average value of the ONU requests of the group divided by the number of groups, or the value rounded up or down, and the sum or average value of the ONU allocations of all groups divided by the number of groups in (5). The value, or the value rounded up or down, the value obtained by dividing the total or average value of the ONU allocations that do not meet the requirements of the ONUs of all groups in (6) by the number of groups, or rounding up the value. Or the value devalued, in (7) the sum of the values of the ONU allocations with the largest allocation in each group divided by the number of groups, or the value rounded up or down, in (8) each group The value of the ONU whose allocation does not wait for the request is the sum of the values of the allocation of the ONU with the largest allocation divided by the number of groups, or the value rounded up or down, and the value allocated by the ONU of each group in (9). Is the sum of the values assigned to the minimum ONU divided by the number of groups, or the value rounded up or down, and in (10) the ONU of each group does not wait for the allocation to be the ONU with the minimum allocation. The sum of the assigned values divided by the number of groups, or the value rounded up or down, 1 in (11) or half the value obtained by dividing the number of ONUs of all groups by the number of groups, or rounded up. Or half of the devalued value. Further, when the groups are arranged in the order of congestion, the group on the congestion side from half may be regarded as heavy congestion, and the other groups may be regarded as light congestion.

The above (1) is the simplest and is suitable when all ONUs are always active. When there is an inactive ONU, it is difficult to determine congestion with the setting of (1) above. The above (2) is suitable when all active ONUs are Greedy transmitters. Here, the Greedy transmitter is a band allocated at any time without controlling the band requested according to the usable band such as TCP / IP so as to be less than the usable band. It means a transmitter that requires the above band. In the case of Greedy, congestion can be determined by a simple setting as described in (2) above.

On the other hand, when at least a part of the ONUs is not Greedy, it is difficult to clearly determine the congestion with the setting as described in (2) above because the request is different for each ONU. The above (3) to (11) take this case into consideration.

The above (3) is a method for determining congestion using the number of ONUs, and the above (4) to (10) are methods for determining congestion using the sum / average / maximum / minimum values of the requests or allocations of the ONUs to be accommodated. Of these, the above (3), (6), (8), and (10) are more elaborate methods for determining congestion, focusing on the request itself or the ONU in which the request is unsatisfied. The above (11) is a method for determining congestion using the number of ONUs in an unfair state due to a large number of communication interruptions and a small number of allocations as compared with other ONUs.

Further, it is desirable that the allocation used in the above (5) to (10) is a band permitted to be transmitted from the OLT, a band actually used, or a band permitted to be transmitted with the support of the request. Bandwidth allocation (unrequired allocation) that is not supported by the request is, for example, "Bandwidth allocation method that realizes low delay in B-PON DBA", Manabu Yoshino, Shinichi Yoshihara, Hiromi Ueda, 2002 Institute of Electronics, Information and Communication Engineers Communication Society. There is something like the one shown in the tournament, B-8-8. There is also unused bandwidth that is requested but not used to suppress fragmentation of transmitted information. For example, it is a fractional band of less than one packet. Therefore, from the viewpoint of fairness, the allocation of (5) to (10) above does not include the above-mentioned unrequired allocation or unused bandwidth allocation, and transmission is permitted with the support of the actually used band or request. It is desirable to use a band that has been set.

The ONUs whose allocation increases due to the group change are the ONUs that remain in the group from which the ONUs are removed by the group change and the ONUs that are added to the lightly congested group by the group change in some cases. If the allocation of ONUs to be regrouped from a heavy congestion group increases, it will be added in the light congestion group rather than the allocation in the previous heavy congestion group, unless the communication interruption time due to the group change is taken into consideration. This is the case when the allocation in the group is large after it has been done. For example, when 3ONUs are distributed between two groups having the same bandwidth used in the explanation of the conventional example, the added ONUs share the bandwidth with 2ONUs before and after the group change, so that they always belong to the heavy congestion group. , The allocation of the ONU does not increase due to group change. Furthermore, considering the communication interruption time due to group change, the allocation is further reduced by group change. In addition, the allocation of ONUs that have belonged to the group to which the ONUs are newly added will decrease.

With respect to ONUs, the observed communication state depends on the fairness achieved. For example, if it is fair that the allocation is equal or close to a predetermined ratio according to the weighting of each ONU, the allocation is observed. The first operation is an operation suitable for this fairness.

When the allocation ratio, which is the ratio of the allocation to the guarantee band, which is the band that must be guaranteed, or the request for transmission permission from the transmitter is fair, the allocation ratio is observed as the communication state. Here, the request may be determined not only according to the declared value of the request from the ONU or the value calculated by smoothing the value, but also according to the past communication history. The communication history may be a history in a window at a fixed time interval in the past, a history in a sliding window for a fixed time, or a history based on a weighted average or an exponential average.

When allocating the bandwidth that can be shared between transmitters at a predetermined ratio (for example, 1: 1: 1 etc.), the total of the bandwidth that can be shared x the ratio of applicable transmitters / the ratio of all transmitters is effective. The allocation ratio to the guaranteed band may be observed as the communication state.

Further, the comparison of the allocation ratios may be limited to the transmitters having a larger request than the allocation. Further, a comparison may be made for a band that is fixedly allocated regardless of the request, a band in which the allocation for the priority class is reduced, a group that is fixedly allocated, or a group other than the group for the priority class.

In the first operation, the ONUs belonging to the heavily congested group that have a large allocation time product are switched, so that only the same ONUs are continuously regrouped and the allocation does not decrease. Bandwidth can be allocated fairly among ONUs. For example, if all ONUs are always requesting more than the allocation in 2 groups of 3 ONUs, the ONUs to be group-changed are sequentially switched in the order of ONU1-> ONU2-> ONU3.

For this reason, the communication interruption time due to group change and the time product belonging to the heavy congestion group and the time product belonging to the light congestion group are equal on average, and the bandwidth allocation within the group is the past ONU. By allocating according to the weighting at each time without considering the allocation history of, fair bandwidth allocation between ONUs across groups becomes possible.

If the difference in congestion between the groups is within a certain range in the first operation and the second and third operations described later, the group change may not be performed. Here, the difference in congestion between groups is within a certain range, for example, when the value is equal to or less than the communication interruption time due to group change, or when the group change is executed, the degree of congestion is improved. When it becomes less than or equal to the value of. Further, in such a case, it is desirable to execute the first operation and the second and third operations described later until the allocation between the individual ONUs falls within a certain range from the fair allocation.

Here, the range within a certain range from the fair allocation is, for example, a value corresponding to the communication interruption time due to the group change or less, or a value corresponding to the degree of fairness improved when the group change is executed.

This is because, due to changes in the requirements of individual ONUs, the difference in congestion between groups may be within a certain range before fairness among ONUs is realized. Under this latter condition, the heavily congested group is the group to which the ONU has less allocation than fair allocation. That is, the determination is made in (11) above. Here, until the difference in congestion between groups is within a certain range, the congestion of the group is determined by a method other than the above (11), and the difference in congestion between the groups is within a certain range by the method used for the determination. In that case, the determination may be switched to the method of (11) above.

The observation time may be observed in a fixed-period observation window, or may be observed in a sliding window in which the observation time is a moving average in a predetermined period in the past, or the past history may be observed exponentially. It may be an exponentially averaged observation that is forgotten and effectively emphasizes the observations in the near future.

There are two ways to observe the band for each ONU: one is to observe the communication interruption time due to group change as the time of zero allocation, and the other is to ignore the communication interruption time due to group change. As an operation, it is desirable to observe the communication interruption time due to group change as the time of zero allocation.

For example, suppose the controller is observing the allocation periodically. Furthermore, the controller shall exponentially forget the observed band, effectively emphasize the observation in the near future, and observe it with the exponentially averaged observation time, taking into consideration the communication interruption time due to group change. .. Further, the request of each ONU is larger than the allocated bandwidth. The band of the j-th group is Gj, the number of accommodated ONUs at time T is Nj (t), the coefficient for forgetting observation is (1-k), and the allocation of the i-th ONU is Bi (t). In this case, the allocation history in the observation time is RBi (t).
RBi (t) = kBi (t) + (1-k) RBi (t)
Is. Here, the assigned Bi (t) of the i-th ONU is Gi / Nj (t) when it belongs to the j-th group, and the disconnection time due to the group change is zero. Further, the coefficient related to forgetting is a value in which the time until forgetting is sufficiently larger than the switching cycle.

[2] Second operation In the second operation, among the ONUs whose group congestion belongs to the heavier congestion group, the congestion of the ONU having a larger time product or the group belonging to the heavier congestion group is heavier. Among the ONUs belonging to the congestion group, the ONUs having a smaller time product that belonged to the lighter congestion group are regrouped. The time product may be, for example, indicated by the value exemplified in the first operation of the congestion for each group and may be the time product, or the congestion may be divided into a plurality of stages and a predetermined value shall be assigned to each, for example, the light congestion may be 0. , Heavy congestion may be assigned to 1 and used as the time product of that value.

In this operation, as compared with the first operation, it is sufficient to observe at least the time spent in the light congestion group and the heavy congestion group without observing the individual ONU bands themselves. Therefore, observation is easy. Further, since the value of the actual bandwidth allocation for each ONU in the group is not used for the group change, it is easy to control the bandwidth allocation in the group and the allocation of the ONU between the groups separately. Fair allocation can be realized if the bandwidth allocation within the group is fair, changes in the distribution status of ONU requests can be ignored before and after switching, and the congestion status between groups due to group change is leveled.

When the execution unit 3 performs group change according to a predetermined cycle or opportunity, it is single so that the difference is eliminated from the allocation target with a low or high allocation history for a predetermined period from the predicted and desired allocation of request or request. Or, instruct to give priority to or suppress group changes for a plurality of predetermined periods.

[3] Third operation In the third operation, the ONUs having a smaller communication interruption time product due to the group change are regrouped among the ONUs whose group congestion belongs to the more heavily congested group. In the same example as the first operation, the time product RTi (t) of the communication interruption time Ti (t) is
RTi (t) = kTi (t) + (1-k) RTi (t)
Is.

If it can be considered that there is no difference in the communication interruption time for each ONU, the communication interruption time product due to the group change may be replaced with the number of switching times.

As for the time product of communication interruption, the allocation amount is more effective than usual by the allocation algorithm, etc., compared to the case where there is no group change, the request history or the information from the external device or the history of the information from the external device is updated. May include a time in which the allocated amount is limited due to insufficient reasons, etc., and the limited time may be included as a time obtained by multiplying the limited amount by a coefficient.

Therefore, in this operation as well, the communication interruption time due to the group change and the time product belonging to the heavy congestion group and the time product belonging to the light congestion group are effectively equalized, and the bandwidth allocation in the group is the past ONU. Similar to the first operation, if allocation is performed according to the weighting at each time without considering the allocation history, fair bandwidth allocation between ONUs across groups is possible.

Further, in this operation, since the controller does not hold the allocation for each group but only the time product of the communication interruption, it is easier to hold and process the history as in the second operation as in the first operation. Is.

[4-1] Fourth operation (No. 1)
The fourth operation (No. 1) suppresses the variation in the communication interruption time product due to the group change for each ONU within a certain range among the ONUs. The range within a certain range is, for example, the communication interruption time or less associated with one group change. At the time of switching, the group may be changed from a heavy congestion group to a light congestion group based on the congestion of the group as in the first to third operations, or an example of the fourth operation (No. 3) described later. Group changes may be performed cyclically as shown in.

When performing group changes in a cyclical manner, it is desirable that the number of active ONUs in each group or the congestion such as demands be leveled. Here, the situation where congestion such as the number of active ONUs or requests is leveled is, for example, the sum of the allocations of ONUs in which the difference in the number of active ONUs is 1 or less between groups or the allocation does not exceed the request. The difference between the groups is the ONU allocation where the allocation does not exceed the request.

In such a situation and when the group change is carried out cyclically during the time when the request situation can be regarded as substantially constant, at most all ONUs may change the group to all groups. If the number of groups with similar congestion and the number of ONUs whose active or allocation does not exceed the request are each, the group may be regrouped to half the number of groups. In either case, in the long term, the communication interruption time due to group change and the time product belonging to the heavy congestion group and the time product belonging to the light congestion group approach each other evenly, and the bandwidth allocation within the group becomes Fair bandwidth allocation between ONUs across groups can be easily achieved by allocating according to the weighting at each time without considering the past allocation history of ONUs.

[4-2] Fourth operation (Part 2)
The fourth operation (No. 2) suppresses the variation in the period during which the ONU is accommodated in the heavy-congested group and the light-congested group within a certain range among the ONUs. The range within a certain range is, for example, the maximum band that can be allocated to the time corresponding to the time of communication interruption due to switching. At the time of switching, the group may be changed from the heavy congestion group to the light congestion group as in the first to third operations, or cyclically as shown in the example of the fourth operation (No. 3) described later. You may change the group. In either case, in the long term, the communication interruption time due to group change and the time product belonging to the heavy congestion group and the time product belonging to the light congestion group approach evenly, and the bandwidth allocation within the group is in the past. By allocating according to the weighting at each time without considering the allocation history of the ONUs, fair bandwidth allocation between ONUs across groups becomes possible easily.

[4-3] Fourth operation (No. 3)
The fourth operation (No. 3) is a combination of the fourth operation (No. 1) and the fourth operation (No. 2). That is, in the observation cycle for observing fairness by observing the communication state of each group, which wavelength each first transceiver (16, 17) stays for, and the communication interruption time due to group change. A group designation instruction is issued so that the time product of the communication interruption time due to the switching of all the first transceivers (16, 17) and the congestion of the group to which the signal belongs is fair.

This operation is the fourth operation (No. 1), in which congestion cannot be leveled between groups, and ONUs that always belong to the heavy congestion group and always belong to the light congestion group in each of the group change cycles. When a situation such as being classified as an ONU occurs, the unfairness can be corrected. In addition, this operation corrects the unfairness even when the communication interruption time due to group change is extremely long and the difference in allocation due to the number of switchings is large in the fourth operation (No. 2). can do. This is because this operation can level the time that belonged to each of the groups of communication interruption time, light congestion, and heavy congestion associated with switching.

The product of the time that belonged to each of the light congestion and heavy congestion groups is simply when the degree of congestion between the light congestion groups and the degree of congestion between the heavy congestion groups are the same throughout the observation time. The product of the time that belonged to each of the light congestion and heavy congestion groups should be taken. If the degree of congestion differs for each group and depending on the time, the product of the time to which each belongs may be calculated by integrating the value obtained by multiplying the belonging time by the degree of congestion. When accumulating the value obtained by multiplying the belonging time by the degree of congestion, the time product belonging to the light congestion group and the time product belonging to the heavy congestion group are not integrated individually, but one integration. May be retained as a value. The communication interruption time due to group change may be accumulated individually, but it was considered as a situation where communication was not possible at all due to severe congestion, and it belonged to the time product and heavy congestion group that belonged to the light congestion group. It may be integrated together with the time product. When integrating together, there is an effect that the value to be retained is reduced.

The following explanation is added using an example in which the allocation makes equality fair. For example, if the wavelengths are two wavelengths, the weighting and switching times for band allocation of all transmitters are the same, one is light congestion and the other is heavy congestion, then light congestion and heavy congestion are approximately equal to all transmitters. It shall belong to the group identified by each wavelength of.

If the switching time is the same, the time product of the number of ONUs of the group identified by the wavelength to which they belong, the sum of the requirements for the guaranteed band, and the sum of the requirements for the band obtained by subtracting the fixed band from the guaranteed band minus the fixed band. It should be even.

For example, the allocated band and its time at the light congestion wavelength for the transmitter i, the allocated band and its time at the heavy congestion wavelength, and the allocated band and its time at the communication interruption time due to the group change are Bli, Tli, Bsi, and Tsi, respectively. , Bhi, and Thi, Bhi, Thi + Bsi, Tsi + Bli, and Tli are controlled to be constant for all transmitters i as in Equation 1.
(Formula 1) ∀i, Bhi / Thi + Bsi / Tsi + Bli / Tli = const
Hereinafter, by allocating cyclically, (Formula 1) is effectively satisfied. Here, for the sake of simplicity, the communication states of the ONUs constituting the group are shown in the same example (all are Greedy) while the group change is completed. However, even if it fluctuates during one round, it can be regarded as the same statistically and in the long run, so it has the same effect as this example. In this case, each value of Equation 1 is (Equation 2) Thi + Tli = Constant,
Bhi = BW / ([N / L]),
Bsi = BW / ([N / L] +1)
Can be expressed by the relationship of. Here, BW is a band for each wavelength, N is the number of transmitters, L is the number of wavelengths, and [] is rounded down to the nearest whole number.

(Embodiment 3)
Although TWDM-PON is exemplified in the first embodiment, it may be applied to TDM-PON. The first embodiment of the TDM-PON is not required to have a function required for time division multiplexing of wavelength resources in the PON section of the ONU-OLT between ONUs such as λ setting switching (DWA). Is similar to.

In the first embodiment, TWDM-PON is exemplified, but a PON that shares resources other than wavelength and time, for example, OFDM (Oriental Frequency-Division Multiplexing) -PON, which divides and multiplexes the frequency resource of electricity of one or a plurality of wavelengths. SCM-PON that divides and multiplexes the frequency resource of electricity of 1 or wavelength, division multiplexing may be performed by OFDM in the optical region, core line division multiplexing may be used in combination, and core division multiplexing (spatial division multiplexing) may be used. It may be used in combination, it may be used in combination with mode division multiplexing, or it may be divided and multiplexed by a code of electric or optical or core wire or core or mode or (orthogonal) frequency or any combination thereof. It may be applied, or only division multiplexing other than time division multiplexing or wavelength division multiplexing may be performed. The same applies if the function corresponding to the function required for time division multiplexing of the wavelength resource of TWDM-PON is read as the function corresponding to the function required for time division multiplexing to each of the multiplexed resources.

In the first embodiment, TWDM-PON is taken as an example, but if the frame for identification in the PON section is treated in the same manner, the same effect can be obtained even with other PONs. For example, in the case of IEEE standard GE-PON, 10GE-PON, etc., if LLID is added instead of the GEM frame and the frame to which LLID is given is made conductive between the SW and other parts. good.
