By clarifying at least a part of the output interface (IF) and enhancing versatility, portability, and expandability, devices with different compliance standards, generations, methods, systems, device types, and manufacturing vendors are used. It is possible to easily share the interface and add a unique function (see, for example, Non-Patent Document 1).

Further, in order to apply the PON to the mobile front hall (MFH: mobile Front Hall), the uplink delay of the PON is reduced, and the packet that can be used in the IP layer of the source node and the packet that can be used in the IP layer of the destination node can be used. One-way air link transmission between the same packets must comply with regulations such as 1 millisecond, and the uplink band is used using the radio resource information generated by the base station (BBU: Base Band Unit) of the mobile station. A method of allocating has been proposed (see Non-Patent Document 2).

(Embodiment 1)
The communication device is, for example, a communication device that executes communication with another communication device by a signal such as an optical signal passing through a communication network such as an optical fiber network such as PON. This communication device is, for example, an OLT (Optical Line Thermal: optical subscriber line end station device). The communication device may be, for example, an OSU (Optical Subscriber Unit). The communication device may be, for example, a combination of an OLT having or not having a switch unit (SW) for switching an optical signal and another switch unit (SW).

The communication device may include a plurality of devices. The communication device transmits the communication between the radio base station and the user equipment.
FIG. 1 is a diagram showing a schematic diagram of communication between a radio base station (BBU), an OLT, an ONU, an RRH (Remote Radio Head), and a user device (UE: User Equipment). The OLT in FIG. 1 is the communication device of the present embodiment. In FIG. 1, the arrows shown between the BBU, OLT, ONU, RRH and UE indicate the direction of information transmission. FIG. 1 shows the flow of transmission such as UL grant, BSR (Buffer Status Report), uplink transmission instruction information, and uplink transmission. For example, exemplifying the UL grant of FIG. 1, the UL grant is transmitted from the BBU to the OLT, and the UL grant transmitted from the BBU is transmitted from the OLT to the ONU, from the ONU to the RRH, and from the RRH to the UE in this order. It is shown to be.

In LTE (Long Term Evolution), the UE receives a buffer status report BSR trigger instruction from a radio base station (for example, eNB (evolved Node B) or BBU) regarding uplink data to be transmitted (“UL grant” in FIG. 1). According to (corresponding to “BSR” in FIG. 1), a scheduling request is made using BSR.

The BSR is described in reference (3GPP TS 36.321), for example, and the total amount of data is calculated for each logical channel group (LCH: Link Channel) in which the data exists. The buffer status report BSR trigger instruction is transmitted by, for example, a MAC (Medium Access CONTROL) control element (CE: Control Element), a radio resource control (RRC: Radio Resource Control) signal, and a physical downlink control channel (PDCCH).

The BSR is transmitted by UL-SCH (Uplink Sharped Channel), which is a radio resource for BSR transmission. The UE transmits the BSR using any of the following cases (1) to (4) as a trigger.
(1): When data or data with higher priority is generated (2): When there is no data to be transmitted (3): The number of surplus bits of MAC PDU (Medium Access CONTROL Protocol Data Unit) is stored in BSR. If it is larger than the required number of bits (Padding BSR)
(4): When the Periodic BSR timer expires (periodic BSR trigger)

When the UE holds an individual uplink resource (PUCCH), the BSR is transmitted by the PUSCH (Physical Uplink Shared Channel) corresponding to the UL grant assigned to the scheduling request. If the UE does not have a separate uplink resource, it initiates a random access (RA) procedure and sends a BSR on the uplink resource corresponding to the UL grant indicated in the random access response (RA response).

Upon receiving the BSR, the BBU transmits the uplink transmission instruction information (Resource Indicator Value Modulation and Coding Scene) to the UE. The UE performs uplink transmission according to the uplink transmission instruction information transmitted from the BBU.

The communication device (OLT) in the present embodiment selects the BSR as the declaration of the user equipment (UE) to the radio base station, and allocates the band to the ONU accommodating the RRH based on the selected BSR value. The BSR used here may be any of Short BSR, Long BSR, and Truncate BSR, and may be any of traffic transmitted to BBU via ONU and OLT accommodating UE. Note that the communication device may allocate a bandwidth allocation that spans a plurality of sections from information such as one BSR. For example, in the case of BSR transmission with a periodic BSR trigger, it may be allocated to a plurality of bandwidth allocation opportunities corresponding to the section. The division into multiple allocation opportunities should be based on the forecasts described below.

In the case of uplink carrier aggregation (UL CA) including site-to-site carrier aggregation (Inter-site CA) that bundles cells under different radio base stations, for example, the radio base station in which the UE resides (eg, macro eNB). The cell under the above is set as a highly reliable primary cell (PCell: primary serving cell), and the cell under the control of another radio base station (other macro cell or small cell) is set as a supplementary secondary cell (additional). SCell: secondary serving cell) can be set, and the connection between the UE and the radio base station of the secondary cell can be managed by the radio base station of the primary cell or the network side.

Therefore, when the UE triggers the BSR in response to the BSR trigger instruction, the BSR may be transmitted by the PUSCH of the primary cell, and the highest or lowest index number (SCell-Index) among the secondary cells may be transmitted. When transmitting to a secondary cell radio base station that has or is presumed to be of good quality, is dynamically specified by a MAC control element, PDCCH (Physical Downlink Control Channel), etc., or is designated as semi-static by an RRC signal. Is the same. Among these BSRs, the BSR relating to the traffic transmitted to the BBU via the ONU accommodating the UE is used. Here, the cell having good quality is, for example, a cell having a good CQI (Cannel Quality Indicator) or a cell having a small number of UL HARQ (Uplink Hybrid Automatic Repeat) retransmissions.
When a single UE, AP, or RRH is accommodated in a plurality of ONUs, the communication device (OLT) may redundantly allocate bandwidth to the plurality of ONUs so as to satisfy the delay regulation, or allocate the bandwidth by the BBU. It is desirable to predict and allocate a single ONU or bandwidth according to the allocation, and the congestion information may be fed back to the BBU.

The OLT may obtain the BSR of the UE directly or by snuffing or proxy response. Specifically, the OLT may acquire the BSR (request information of FIG. 1) from the UE itself or the BSR (request information of FIG. 1) from the BBU as shown in FIG. , Or the route from UE to BBU, that is, RRH, ONU, OLT may be acquired by snuffing, proxy response, or the like. The OLT may acquire information such as BSR from any of UE, RRH, ONU, and BBU.

In particular, when the BSR cannot be read due to encryption or the like, the OLT may set a proxy or the like for terminating the exchange related to the BSR on the path from the UE to the BBU, decrypt the code, and read the BSR. The device that responds by proxy is seen as a BBU from the bottom (UE) and a UE from the top (BBU). In this way, the OLT pretends to be a BBU to the UE and pretends to be a UE to the BBU by making a proxy response. The delay time associated with the surrogate response is added or subtracted from the transmission time of the requesting UE, added to or subtracted from the indicated time, or a combination thereof so that at least one of the UE and the BBU is not affected. It is desirable to do. The OLT allocates the upstream band of the PON based on the acquired BSR value.

The OLT predicts the arrival time at the ONU and the amount of transmission data when the UE transmitting according to the uplink transmission instruction information based on the BSR transmits at the transmission start time, and allocates the bandwidth. If the time specified by the BBU is substantially constant from the manufacturer, model, etc. of the device, the OLT holds and adds the value of that time. If the time indicated by the BBU is not constant from the manufacturer, model, etc. of the device, the OLT may predict from the BSR and the radio resource control signal, or the BSR and the continuity information.

If the OLT gives an instruction at the time after instructing the transmission of the reported data in the BSR made before the BSR, the OLT calculates the time required to send the reported data in the BSR made before the BSR. Instruct after time. If the UE or LCH has a priority, the OLT allocates the band at a time according to the priority. For example, the OLT may predict and allocate bandwidth only to the high priority UE or the high priority LCH based on the BSR data, and may allocate the low priority bandwidth based on the accumulated amount of the ONU buffer, or the high priority UE. Alternatively, after allocating the bandwidth to the high-priority LCH, the low-priority bandwidth allocation may be performed only when the remaining bandwidth remains.

Allocation to the ONU is wasted if the upstream traffic from the UE is before the arrival of the ONU, so the time from the predicted arrival time to the estimated arrival time plus the waiting time allowed by the ONU. It is desirable that there is, and the amount of data may be larger than the expected amount if interference with other traffic can be ignored.

Since the bandwidth allocation of the OLT predicts and allocates the uplink transmission instruction information by the BBU, it is desirable to also include an algorithm for calculating the uplink transmission instruction information provided by the BBU and calculate using that algorithm. The OLT acquires the usage status of the bandwidth allocated to the ONU, compares the usage status with the BSR, predicts the calculation rule of the uplink transmission instruction information for the BSR, and allocates the bandwidth based on the predicted calculation rule. May be good. Further, the OLT acquires the uplink transmission instruction information, compares the uplink transmission instruction information with the BSR, predicts the calculation rule of the uplink transmission instruction information for the BSR, and allocates the band based on the predicted calculation rule. May be good.
It is desirable to take into account the congestion state of the BSR from the information from other OLTs accommodated by the BSR and the continuity information of those or the BSR itself. Specifically, in the OLT, if the BSR is congested, the allocation for the BSR request is delayed, so the band allocation is made according to the delay amount.

In addition, it is desirable to allocate an excessive amount of bandwidth until the rule for prediction is acquired, and to allocate according to the rule after the rule is acquired. Considering that the prediction also deviates from the prediction, the BSR is more than the predicted value. Value or predicted value or usage status or value corresponding to uplink transmission instruction information or difference between predicted value and BSR value or difference between usage status and BSR value or value corresponding to uplink transmission instruction information and BSR value Bandwidth may be excessively allocated by adding the range of fluctuations such as the dispersion value of any one of the differences with or a combination thereof.

In particular, when adjusting the prediction calculation rule using the usage status, when transmitting the PON section by at least one unit from the predicted value, for example, in frame units, the maximum value of the frames that can be transmitted by the UE and the transmission of the UE. When the PON section is transmitted by dividing the possible frame, it is desirable to over-allocate more than the unit of PON section transmission such as TQ. Then, when the surplus value is used, it is desirable to modify the calculation rule used for the prediction. Excessive bandwidth allocation is desirable when modifying the calculation rules.

In the above example, BSR has been described as an example of the declaration of the user equipment to the radio base station, but when the uplink transmission instruction information is BBU based on CQI, CQI may be used as the declaration of the user equipment. Since the maximum band that can be transmitted can be calculated from the CQI, the maximum band corresponding to the CQI for the channel with the highest quality or the lowest congestion may be used as the allocated band, or the BBU can be given from the CQI value of another UE. Bandwidth may be divided.

Even when CQI is used, the bandwidth allocation of the OLT predicts and allocates the uplink transmission instruction information by the BBU. Therefore, it is desirable to have an algorithm for calculating the uplink transmission instruction information provided by the BBU and calculate using that algorithm. .. In addition, the OLT acquires the usage status of the band allocated to the ONU, compares the usage status with the band corresponding to the CQI, predicts the calculation rule of the uplink transmission instruction information for the CQI value, and calculates the predicted value. It may be assigned based on the rules. Further, the OLT acquires the uplink transmission instruction information, compares the bandwidth corresponding to the CQI with the uplink transmission instruction information, predicts the calculation rule of the uplink transmission instruction information with respect to the CQI value, and uses the predicted calculation rule. It may be assigned based on.

Further, the OLT may convert the BSR information into another format (for example, the format of reporting the buffer amount from the ONU to the OLT) by an intermediate device (for example, ONU or the like). In this case, the OLT may map the logical channel group to a queue or LLID or Alloc-ID. When converting to an ONU declaration, there is an effect that bandwidth usage can be reduced as compared with transmission separately without conversion, and there is an effect that allocation processing can be performed on the OLT side in the same manner as traffic from the UE. From the viewpoint of transmitting the traffic from the UE with a lower delay than the others, it is desirable that the OLT side does not perform the same allocation processing as the traffic from the UE. When the band conversion between ONU and OLT is not performed, there is an effect that the time and processing required for conversion can be reduced as compared with the case of conversion, which is desirable from the viewpoint of reducing the transmission delay.

In any case, it is desirable that the BSR and CQI are not encrypted, but it is desirable that the format of the BSR and CQI output by the UE is not specially changed for OLT bandwidth allocation. Here, the bandwidth allocation calculation and the determination of the calculation rule for the ONU are carried out by the OLT, but they may be carried out by the application software in the OLT, or by the platform composed of the combination of the middleware and the hardware of the OLT. It may be carried out by a device such as a server outside the OLT. In particular, it is desirable from the viewpoint of reducing OLT resources that the determination of calculation rules that require a large amount of arithmetic processing is performed by a device outside the OLT. With the above configuration, as shown in FIG. 1, the OLT in the present invention provides information at a time clearly earlier than the conventional method (BBU uses uplink transmission instruction information for the UE) shown in Non-Patent Document 2. Can be obtained. Then, since the OLT allocates the band based on the acquired band, lower delay transmission becomes possible.

FIG. 2 is a diagram showing a configuration example of the communication device 1 of the present embodiment. In FIG. 2, only the functional blocks related to the present embodiment are extracted and shown. The communication device 1 includes an acquisition unit 2 that acquires a declaration of a user device, and a band allocation unit 3 that allocates a band based on the acquired declaration. The acquisition unit 2 sniffs and acquires the declaration of the user device. In addition, the acquisition unit 2 acquires the declaration of the user device by proxy response. Here, the declaration of the user equipment is the buffer status report BSR or CQI as described above.

If there is an explicit allocation rule for each device, each vendor, or each own company for BSR, the band allocation unit 3 allocates the band according to the rule. If the rule is unknown, the band allocation unit 3 acquires the usage status of the band allocated to the ONU, compares the usage status with the BSR, predicts the calculation rule of the uplink transmission instruction information for the BSR, and predicts the usage status. Bandwidth may be allocated based on the calculated calculation rule, or the uplink transmission instruction information is acquired, the BSR and the uplink transmission instruction information are compared, and the calculation rule of the uplink transmission instruction information for the BSR is predicted and predicted. Bandwidth may be allocated based on the calculation rule. Further, the band allocation unit 3 acquires the usage status of the band allocated to the ONU, compares the band corresponding to the CQI with the usage status, predicts the calculation rule of the uplink transmission instruction information with respect to the CQI value, and determines the calculation rule thereof. It may be assigned based on the predicted calculation rule, or the uplink transmission instruction information may be acquired, the bandwidth corresponding to the CQI and the uplink transmission instruction information are compared, and the calculation rule of the uplink transmission instruction information for the CQI value is predicted. Then, the allocation may be made based on the predicted calculation rule. Further, the band allocation unit 3 may allocate the band in consideration of either the information on the priority or the congestion status of the radio base station in the prediction. The specific processing is as described above. In addition, the bandwidth allocation unit 3 converts the logical channel group into a form of reporting the buffer amount from the ONU to the OLT by mapping the logical channel group to a queue or an LLID or an Alloc-ID.

The band allocation unit 3 may divide the calculation rule into a function of predicting and a function of allocating. The band allocation unit 3 itself or the predictive function is a device that is a component of any part of the device or a virtual communication device, for example, the transmission / reception unit 11 and the switch unit 12 shown in FIG. 8 described later. It may be arranged in any of the switch unit 13, the control unit 14, the proxy unit 15, and the external server 16, or in an external cloud or the like. The prediction function requires a large amount of computer resources, and if the calculation rule itself does not change so much over time, it is processed that there is a large amount of computer resources such as the cloud and it is used only when necessary. In terms of capacity, it is also suitable from the viewpoint of resource utilization efficiency. In particular, when the prediction function is not provided on the device, the API described later regarding the usage status, allocation history, and radio information does not have to be on the device.

Next, as an example, the operation and the like will be illustrated on the assumption that the communication device is an OLT of a PON conforming to the ITU-T recommendation such as a TWDM (Time and Waveringx Division Multiplex) -PON system. Here, TWDM-PON is used, but the PON may be a PON other than the TWDM-PON conforming to the ITU-T recommendation. For example, the PON may be an IEEE standard compliant PON such as GE (Gigabit Ethernet®-PON, 10 GE-PON, etc.). The TC (Transmission Communication) layer and the PMD (Physical Medium Dependent) layer are the same if they are read as the corresponding layers in the standard.

The communication device 1 includes hardware or software, or a combination thereof, or a componentized function thereof. For example, the communication device 1 is realized by using a general-purpose input / output interface (for example, FASA (Flexible Access System Architecture) application API), which has different functions for each service or each communication carrier. An access that provides an application that is a software component (for example, a FASA application) and a function that does not need to be changed according to a service or request because the application is provided with the generalized input / output interface and is standardized. It includes a basic component of a network device (for example, a FASA board). Here, by using a general-purpose input / output interface, it is easy to add or replace functions, and services of various requirements can be provided flexibly and promptly. In addition, in this specification, an application is also referred to as an "application".

The exchange between the parts is performed, for example, via the middleware unit 120 described later, but an original transfer path or means of the communication device 1 may be used, OpenFlow, Netconf / YANG, or SNMP (Simple Network Management Protocol). You may use standardized means such as.

Further, the communication between the parts may be any of the internal wiring, the backboard, the OAM unit, the main signal line, the dedicated wiring, the operation system, the controller, the control panel (Cont panel), or the like. When the communication between parts is directly terminated and input, it may be encapsulated in the OAM unit or the main signal. Communication between parts may be terminated at any point and input via a route such as internal wiring, backboard, OAM section, main signal line, dedicated wiring, operation system, controller or control panel. .. When using the OAM section or the main signal line, it is desirable to encapsulate it in the OAM section or the main signal. When passing through the main signal line, it is desirable to distribute it at the OSU or the switch section at another location.

In this embodiment, the communication device 1 is an interface that conveys a value reported by the UE to a radio base station or a processed value thereof in order to allocate an ONU uplink band in an application such as a FASA application or a platform such as a FASA platform. To be equipped. The value exchanged by the interface is the value of BSR or CQI itself, or the value contained therein, for example, if the time when the uplink signal from the UE is transmitted to the BBU can be determined and the UE and the logical channel can be identified, the value of BSR or CQI can be used. Only the corresponding value is required. For example, when only one UE is accommodated in the ONU, the ONU in which the UE is accommodated may be identified from the arrival time at the OLT, and the logical channel may be Truncate BSR or Short BSR.

In the case of Long BSR, at least an identifier is needed to identify the logical channel. Desirably, it is accompanied by an identifier that identifies the UE and the logical channel. More preferably, it is accompanied by the time when the UE raises a report such as BSR, the time when it is received by the ONU, or the time when the OLT sends it to the BBU. These times are used to predict the uplink transmission instruction information of the radio base station to the UE. For example, in the case of a radio base station that gives an uplink transmission instruction at a predetermined time predetermined from the time transmitted by the UE, the ONU transmission permission for transmitting the uplink information transmitted by the UE at that time is given. For example, in the case of a wireless base station that gives an uplink transmission instruction at a predetermined time predetermined from the time received by the wireless base station, ONU transmission permission for transmitting uplink information transmitted by the UE at that time is given. Just do it.

When calculating the calculation rule using either the usage status or the uplink transmission instruction of the wireless base station, in order to identify the usage status or the uplink transmission instruction of the wireless base station corresponding to the information such as BSR used for the allocation. It is desirable to have the identifier of. For identification, for example, the time of arrival or allocation, the identification number of allocation, etc. can be used.

(Embodiment 1-1)
In the first embodiment, the configuration of the communication device constituting the communication system used for the TWDM-PON will be described. The communication device described in the 1-1 embodiment is used as the communication device 1 shown in FIG. Hereinafter, examples 1 to 6 will be described as examples of the architecture of the communication device. The architecture of the communication device constituting the communication system may be an architecture other than the first to sixth examples described below. For example, the software part of the communication device in the first to sixth examples of the architecture may be a hardware part.

(First example of architecture)
FIG. 3 is a diagram showing a first example of the architecture of the communication device. In the first example of the architecture, the communication device has a non-general-purpose device-dependent section 110 whose operation depends on the device, a middleware section 120 which hides the difference in hardware and software of the device-dependent section 110, and a device-dependent operation. It is provided with a general-purpose device-independent application unit 130 that does not. Therefore, the device-dependent section 110 (vendor-dependent section) is a functional section that depends on the standard to which the device of the communication device conforms and the manufacturing vendor of the device. In other words, the device-dependent unit 110 has low compatibility with other communication devices, and cannot be used as it is for newly manufactured communication devices (particularly, devices having different conforming standards or manufacturing vendors). The device-dependent unit 110 executes one or more functions provided in the network device.

Further, the device-independent application unit 130 is a functional unit that does not depend on the standard to which the device of the communication device conforms or the manufacturing vendor of the device. In other words, the device-independent application unit 130 has high compatibility with other communication devices, and can be used as it is for newly manufactured communication devices (particularly, devices having different conforming standards and manufacturing vendors). Specific examples of the application provided in the device-independent application unit 130 include an application that performs setting processing in a network device, an application that performs setting change processing, an application that performs algorithm processing, and the like.

The middleware unit 120 and the device-independent application unit 130 are connected via the device-independent API 21. The device-independent API 21 is an input / output IF that does not depend on the device.

The device-dependent unit 110 includes, for example, a hardware unit 111 (PHY), a hardware unit 112 (MAC), a software unit 113, and an OAM (Operation Management and Management) unit 114. The hardware unit 111 (PHY), the hardware unit 112 (MAC), the software unit 113, the OAM unit 114, and the middleware unit 120 are connected via the device-dependent API 23. The device-dependent API 23 is a device-dependent input / output IF. The device-dependent unit 110 further includes a NE (Network Element) management / control unit 115. The NE management / control unit 115 and the middleware unit 120 are connected via the device-dependent API 25. The device-dependent API 25 is an input / output IF that depends on the device.

What kind of function is the device-dependent unit 110 or the device-independent application unit 130 is derived from the limitation derived from the processing for realizing the middleware unit 120 or the device-independent application unit 130, for example, the processing capacity of the software. In addition to the restrictions to be applied, it may be determined according to the frequency of function updates, the importance of extended functions, and the like. As a result, the communication device can facilitate the flexible and quick addition of the extended function unit (unique function unit) by the device-independent application unit 130, and can provide the communication service in a timely manner.

For example, the device-dependent unit 110 or device-independent, giving priority to functions that are frequently updated or functions that contribute to communication service differentiation, such as DBA (Dynamic Bandwidth Assignment) that improves the priority processing of the main signal and the line utilization efficiency. You may decide to use the application unit 130. Further, the device-independent application unit 130 may be used because the difference is small with respect to at least one of the standard, generation, method, system, device type, and manufacturing vendor to which the device to be shared conforms.

Any of the compliant standards, generations, methods, systems, equipment types, manufacturing vendor features, even if it is not optimal for at least one of the compliant standards, generations, methods, systems, equipment types, and manufacturing vendors. In order to generalize the above, a common IF for executing the function may be used. The common IF may include IFs and parameters that are not used in any of the standards, generations, methods, systems, device types, and manufacturing vendors to which the device-dependent unit 110 conforms.

The middleware unit 120 shown in FIG. 3 and FIG. 4 described later, the driver of the device-dependent unit 110 shown in FIGS. 5 and 6 described later, and the device-dependent application unit 150 shown in FIGS. 4 and 6 described later ( In at least one of the vendor-dependent application section), a conversion function section that converts IFs and parameters to correspond to the device-dependent section 110, and a function section that automatically sets corresponding to the missing IFs and parameters are further added. You may prepare.

The device-dependent unit 110 shown in FIG. 3 includes a hardware unit 111 (PHY), a hardware unit 112 (MAC), and a software unit 113. The hardware unit 111 (PHY) executes from the physical layer to the processing related to optical transmission / reception (PHYsical sublayer processing). The hardware unit 112 (MAC) executes a MAC (Media Access Control) process. The hardware unit 111 (PHY) and the hardware unit 112 (MAC) depend on conforming standards and manufacturing vendors. The software unit 113 executes device-dependent drivers, firmware, applications, and the like.

In addition to these, the hardware unit 111 (PHY) and the hardware unit 112 (MAC) of the device-dependent unit 110 may include a general-purpose server, a layer 2 switch, and the like. The device-dependent unit 110 does not have to include the hardware unit 112 (MAC). The device-dependent unit 110 does not have to include a part of the hardware unit 111 (PHY). For example, the device-dependent unit 110 does not include low-level signal processing such as modulation / demodulation signal processing, forward error correction (FEC, Forward Error Correction), code decoding processing, and encryption processing, and may have only optical-related functions. Good. The device-dependent unit 110 does not have to include a PCS (Physical Coding Sublayer) which is a part for encoding data. The device-dependent unit 110 does not have to include a PMA (Physical Medium Attitude) for serializing data and a PCS. The device-dependent unit 110 does not have to include a PMD connected to a physical medium. In the device-dependent unit 110, when the middleware unit 120 directly drives, controls, operates or manages the hardware unit 111 (PHY) and the hardware unit 112 (MAC) of the device-dependent unit 110 without going through the software unit 113. The software unit 113 may not be provided.

The device-independent application unit 130 is, for example, an extended function unit 131-1 to 131-3 (extended function A, extended function B and extended function C in FIG. 3), a basic function unit 132, and a management / control agent unit. It is provided with 133. The management / control agent unit 133 exchanges data from the EMS (Element Management System) 140.

In the figure, the EMS 140 and the external device 160 are connected to the device-independent application unit 130 via the middleware unit 120, but the EMS 140 and the external device 160 are not necessarily connected to the device-independent application unit 130 via the middleware unit 120. You don't have to. The EMS 140 and the external device 160 may be appropriately connected to the middleware unit 120 or may be directly connected to the device-independent application unit 130, if necessary. Further, although it is expressed as "connecting via the middleware unit 120", this expression is an expression from the viewpoint of the device-independent application unit 130. In reality, device-independent applications are connected to each other via the middleware unit 120 after the connection by hardware.

Hereinafter, matters common to the extended function units 131-1 to 131-3 will be referred to as "extended function unit 131" by omitting a part of the reference numerals. The EMS 140 is, for example, a NE controller. The device-independent application unit 130 may not include any of the extended function unit 131, the basic function unit 132, and the management / control agent unit 133, and the management / control agent unit 133 is the basic function unit 132. The management / control agent unit 133 may be included in the basic function unit 132 or the middleware unit 120.

The device-independent application unit 130 may further include a configuration other than the extension function unit 131, the basic function unit 132, and the management / control agent unit 133. For example, when the extended function unit 131 is unnecessary, the device-independent application unit 130 does not have to include the extended function unit 131. Further, the device-independent application unit 130 may include one or more extended function units 131.

It is preferable that the extension function unit 131 can be added, deleted, replaced or changed independently without unnecessarily affecting other functions. For example, the extension function unit 131 may be added, deleted, replaced, or changed as appropriate when, for example, a multicast service or an extension function unit 131 that executes power saving measures is required according to a service request. ..

The basic function unit 132 may be included in the device-independent application unit 130 as a part of the extension function unit 131, or may be replaced by a function unit lower than the middleware unit 120. When the extended function unit 131 includes the basic function unit 132, the device-independent application unit 130 does not have to include the basic function unit 132. When a functional unit lower than the middleware unit 120 substitutes for the basic function unit 132, the device-independent application unit 130 does not have to include the basic function unit 132. When the extended function unit 131 includes the basic function unit 132 and the function unit lower than the middleware unit 120 substitutes for the basic function unit 132, the device-independent application unit 130 does not have to include the basic function unit 132.

When the management / control agent unit 133 does not receive communication from the EMS 140 and automatically sets according to a predetermined setting, the management / control agent unit 133 does not have to input / output with the EMS 140. Further, when the management / control agent unit 133 does not have the management setting function and the other device-independent application unit 130, the basic function unit 132, or the device-dependent unit 110 has the management setting function, the device-independent application unit 130 The management / control agent unit 133 may not be provided.

Information may be directly input / output between the EMS 140 and the device-independent application unit 130. Further, the device-dependent unit 110 may be replaced by the NE management / control unit 115 and the device-dependent application unit 150 (see FIG. 4 and FIG. 6 to be described later) which is a lower function unit of the NE management / control unit 115. Good.

When the management / control agent unit 133 automatically sets according to a predetermined setting, it is not necessary to input / output information to / from the EMS 140. Further, when the management / control agent unit 133 does not have the management setting function and the other device-independent application unit 130, the basic function unit 132, or the device-dependent unit 110 has the management setting function, the device-independent application unit 130 manages. -The control agent unit 133 does not have to be provided. Information may be directly input / output between the EMS 140 and the device-independent application unit 130.

An example of input / output between the device-independent application unit 130 and the device-dependent unit 110 is as follows.
For example, the DBA application unit and the protection application unit input / output information to and from the embedded OAM engine (Embedded OAM Engine) of the TC layer. The DWBA (Dynamic Wavelength and Bandwidth Authentication) application and the ONU registration authentication application unit input / output information to and from the PLOAM engine of the TC layer. The power saving application unit inputs / outputs information to and from the OMCI and the L2 main signal processing function unit (L2 function unit). The MLD (Multicast Listener Discovery) proxy application unit inputs and outputs information to and from the L2 functional unit. The low-speed monitoring application (OMCI) inputs and outputs information to and from OMCI. The OMCI and L2 functional units operate the XGEM framer (XGPON Encapsulation Method Framer) and encryption. Here, the DWBA and the DBA may be separate, integrated, or combined. For example, the management / control agent unit 133 is an application unit of the maintenance operation function, and inputs / outputs information to and from EMS140, which is an NE controller or the like for the NE management / control unit 115.

The implementation of the device-independent application unit 130 may have a priority. For example, the management / control agent unit 133 has the highest priority. Below the second priority is, for example, a DBA application, a DWBA application, a power saving application, an ONU registration authentication application, an MLD proxy application, a protection application, and a low-speed monitoring application (OMCI).

The device-independent application unit 130 describes the device vendor, method, device type, device generation, for example, ITU-T G.M. TWDM-PON conforming to the 989 series and ITU-T G. XG-PON conforming to the 987 series and ITU-T G. G-PON conforming to the 984 series and ITU-T G. It is an application that operates regardless of any of the B (Broadband) PONs that conform to the 983 series. The device-independent application unit 130 differs in device vendor, method, device type, device generation, for example, 10GE-PON conforming to IEEE802.3av and IEEE1904.1, and GE-PON conforming to IEEE802.3ah. It is an application that works regardless of.

As the application of the extended function unit 131, only the application for driving the functions prepared for some vendors, methods, types, and generations and the devices of some vendors, methods, types, and generations via the device-independent API 21. It may include an app that drives the features provided for.

The management / control agent unit 133 inputs / outputs to and from the EMS 140 and the middleware unit 120. The middleware unit 120 inputs / outputs NE management information and control information to / from the NE management / control unit 115. The NE management / control unit 115 may directly send / receive NE management information and control information to / from the EMS 140 without going through the middleware unit 120, or may send / receive NE management information and control information via the management / control agent unit 133. You may send and receive.

The middleware unit 120 inputs / outputs information via the device-independent application unit 130 and the device-independent API 21. The middleware unit 120 inputs / outputs information to / from the OAM unit 114 of the device-dependent unit 110, the driver, the firmware, the hardware unit 111 (PHY), or the hardware unit 112 (MAC) via the device-dependent API 23. The middleware unit 120 outputs the input information as it is or in a predetermined format. For example, if the output destination is each part of the device-independent application unit 130, the middleware unit 120 converts the information into the input format of each part of the device-independent API 21. If the output destination is the OAM unit 114 of the device-dependent unit 110, the driver, the firmware, the hardware unit 111 (PHY) or the hardware unit 112 (MAC), the middleware unit 120 is the device-dependent API 23 in the form of input to each. After converting to the format, or after terminating and performing the predetermined processing, the information is transmitted to the output destination.

At the time of input, the middleware unit 120 deletes unnecessary input information at each input destination, and if there is insufficient information, it can collect and supplement it via another device-independent API 21 or device-dependent API 23. desirable. Further, when inputting to the middleware unit 120, it may be broadcast or multicast to broadcast to a related application or the like.

In FIG. 3, the middleware unit 120 and the device-dependent unit 110 are illustrated as a single unit, but each may be composed of a plurality of units. When the hardware of the device-dependent unit 110 includes a plurality of processors, the middleware unit 120 may input / output across the processors and hardware by using interprocessor communication or the like. The device-independent application unit 130 and the device-independent application unit 130 may be arranged in the user space on a single processor as an execution program such as a DLL (Dynamic Link Library), or on a plurality of processors. It may be arranged in the user space.

Further, the device-independent application unit 130 may be arranged in the kernel space after securing input / output IFs such as API, or may be arranged together with the middleware unit 120 having an IF that can be independently replaced with firmware or the like. Alternatively, it may be incorporated into firmware or the like and recompiled. The user space and kernel space may be any combination for each device-independent application unit 130.
The device-independent application unit 130 corresponding to the same function may be implemented in both the user space and the kernel space. In this case, for example, it may be switched and one of them may be selected, both may be processed in cooperation, or the actual processing may be performed by only one of them. The same applies to the software of the device-dependent unit 110.

Desirably, the more high-speed processing such as main signal processing, DBA processing, and low-layer signal processing is required, the more there is a trade-off with the immediacy of expandability / replacement, but high-speed processing with less overhead is expected. It is desirable to incorporate it in the kernel space or firmware. The processor in which the device-dependent application unit 150 (see FIGS. 4 and 6 described later) is also actually used from the viewpoint of the influence on other programs due to the limitation of the bus and speed due to the inter-processor communication, the occupation of the communication path, and the like. It is desirable to place it in the user space, kernel space, or firmware of the processor that performs processing or a processor in the vicinity thereof. However, in order to reduce the capacity of the processor performing the actual processing or a processor in the vicinity thereof, the communication cost due to the inter-processor communication increases, but the processing may be performed by a remote processor.

It is desirable that the device-independent API 21 is provided in the middleware unit 120 in advance assuming the extended function unit 131 to be added, but it is necessary in a form of suppressing modification of the device-dependent API 23 and other device-independent application units 130. It may be added or deleted accordingly.

In this example, the softened area is the basic function unit 132, the management / control agent unit 133, the extended function unit 131, and the middleware unit 120, but the softened area is the service adaptation (encryption, fragment processing, GEM). Framed / XGEM framing, PHY adaptation FEC, scrambling, synchronous block generation / extraction, GTC (GPON Forward Transmission) framing, PHY framing, SP conversion, coding method may also be targeted. Architecture softening function An example of implementation of the above and an example of function deployment corresponding to the hardware unit will be described. The function deployment includes, for example, a software function in a network device or an external server. This is the same in other examples.
(Second example of architecture)

When the management / control agent unit 133 automatically sets according to a predetermined setting, it is not necessary to input / output information to / from the EMS 140. Further, when the management / control agent unit 133 does not have the management setting function and the other device-independent application unit 130, the basic function unit 132, or the device-dependent unit 110 has the management setting function, the device-independent application unit 130 The management / control agent unit 133 may not be provided.

The EMS 140 and the device-independent application unit 130 may be directly input / output. When the lower level of the middleware unit 120 replaces all of the basic function unit 132, the device-independent application unit 130 does not have to include the basic function unit 132.

In the communication device shown in FIG. 4, the device-dependent application unit 150 may input / output information via the middleware unit 120, or may directly input / output information from the management / control agent unit 133, or both. Information may be input / output to / from any of the above, or may be directly input / output to / from EMS140. Further, when the device-dependent application unit 150 is automatically set according to a predetermined setting without receiving communication from the EMS 140, and management and control information can be acquired from the EMS 140 via the middleware unit 120, the device The independent application unit 130 does not have to include the management / control agent unit 133.

The device-independent application unit 130 inputs information via the middleware unit 120 at least between the hardware unit 111 (PHY) and the hardware unit 112 (MAC) of the device-dependent unit 110 or between the software unit 113. Output. The device-independent application unit 130 inputs / outputs to each other via the middleware unit 120 as needed. In particular, when the device-independent application unit 130 executes control or management according to the information input / output to / from the EMS 140, the device-independent application unit 130 transfers the information to the management / control agent unit 133 that receives the communication from the EMS 140. Input / output.

The NE management / control unit 115 inputs / outputs NE management information and control information to / from the management / control agent unit 133 via the middleware unit 120. The NE management / control unit 115 may directly input / output NE management information and control information to and from the EMS 140 without going through the middleware unit 120.

The device-dependent application unit 150 inputs / outputs NE management information and control information to / from the management / control agent unit 133. The device-dependent application unit 150 may directly input / output information to / from the EMS 140 without going through the management / control agent unit 133. The management / control agent unit 133 inputs / outputs information between the EMS 140, the middleware unit 120, and the device-dependent application unit 150. The middleware unit 120 inputs / outputs NE management information and control information to / from the NE management / control unit 115.

Information is input / output to / from the hardware unit 112 (MAC) via the device-dependent API 23.

The middleware unit 120 shown in FIG. 4 is input as it is or in a predetermined format, similarly to the middleware unit 120 shown in FIG. It is desirable that the device-independent API 21 is provided in the middleware unit 120 in advance assuming the extended function unit 131 to be added later, but if necessary, the device-dependent API 23 and other device-independent application units 130 may be modified. It may be added or deleted in a suppressed form.

(Third example of architecture)
FIG. 5 is a diagram showing a third example of the architecture of the communication device. In FIG. 5, instead of the middleware unit 120 described in the first example of the architecture shown in FIG. 3, the basic function unit 132 is the hardware unit 111 (PHY), the hardware unit 112 (MAC), and the extended function unit 131. Input and output with. The other device-independent application unit 130 is the same as the first example of the architecture.

In the figure, the EMS 140 and the external device 160 are connected to the device-independent application unit 130 via the basic function unit 132, but the EMS 140 and the external device 160 are not necessarily the device-independent application via the basic function unit 132. It is not necessary to connect to the unit 130. The EMS 140 and the external device 160 may be appropriately connected to the middleware unit 120 or may be directly connected to the device-independent application unit 130, if necessary. Further, although it is expressed as "connecting via the middleware unit 120", this expression is an expression from the viewpoint of the device-independent application unit 130. In reality, device-independent applications are connected to each other via the middleware unit 120 after the connection by hardware.

Compared with the first example of the architecture, the third example uses the middleware unit 120 including the device-dependent APIs 23 and 25 for each device having at least one of a compliant standard, generation, method, system, device type, and manufacturing vendor. No need to create. As a result, the communication device of the third example of the architecture has the effect of generalizing and porting more functions between generations between devices, facilitating verification of connectivity, and making the functions of the devices robust.

The communication device according to the third example of the architecture includes a device-dependent unit 110 and a device-independent application unit 130. The device-dependent section 110 includes a hardware section 111 (PHY) and a hardware section 112 (MAC), and a hardware section 111 (PHY) and a hardware section 112 (MAC), which depend on a compliant standard or a device manufacturing vendor. It is provided with a software unit 113 such as a driver and firmware for driving the above. The driver or the like hides the difference in the device-dependent unit 110.

The device-independent application unit 130 includes an extended function unit 131 and a basic function unit 132. The basic function unit 132 uses a device-independent API 27 (IF for porting) via a driver that hides the difference between the hardware unit 111 (PHY) and the hardware unit 112 (MAC) and the device-dependent software unit 113. Connect with the dependent unit 110. The device-independent application unit 130 uses a driver that hides the difference between the hardware unit 111 (PHY) and the hardware unit 112 (MAC) and the device-dependent software unit 113, and then hardware unit 111 (PHY) and hardware. Data is input and output between the hardware unit 112 (MAC) and the device-dependent software unit 113.

The basic function unit 132 and the extended function unit 131 are connected via a device-independent API 22 (expansion IF). The basic function unit 132 and the device-dependent unit 110 are connected via the device-independent API 27. The basic function unit 132 in the device-independent application unit 130 inputs information between the hardware unit 111 (PHY), the hardware unit 112 (MAC), and the extension function unit 131 instead of the middleware unit 120. Output.

The device-independent application unit 130 inputs / outputs to and from each other via the basic function unit 132 as needed. The extended function unit 131 of the device-independent application unit 130 inputs / outputs information via the basic function unit 132 and the device-independent API 22. The basic function unit 132 inputs and outputs information via the extension function unit 131 and the device-independent API 22, and the OAM unit, driver, firmware, hardware unit 111 (PHY) and hardware unit 112 (MAC) of the device-dependent unit 110. ) And the device-independent API 27 to input and output information.

Similar to the middleware unit 120 shown in FIG. 3, the basic function unit 132 inputs information as it is or in a predetermined format. For example, in the case of another device-independent application unit 130, the basic function unit 132 converts the input format into the device-independent API 22 format, and the device-dependent OAM unit, driver, firmware, and hardware unit are used. If there is, the information is input after being converted into the device-independent API 22 format of the input format, or after being terminated and performing a predetermined process. At the time of input, the basic function unit 132 deletes unnecessary input information at each input destination, and if there is insufficient information, collects and supplements it via another device-independent API 22 or device-independent API 27. Is desirable. However, the basic function unit 132 may broadcast or multicast the input to the input destination to broadcast the input to the related application or the like.

The device-independent application unit 130 includes, for example, extended function units 131-1 to 131-3 and basic function units 132. The device-independent application unit 130 does not have to include either the extended function unit 131 or the basic function unit 132. The device-independent application unit 130 may further include functional units other than the extended function unit 131 and the basic function unit 132. For example, when the extended function unit 131 is unnecessary, the device-independent application unit 130 does not have to include the extended function unit 131.

It is preferable that the extended function unit 131 can be added or deleted independently without affecting other functions. For example, when the extension function unit 131 is used for multicast service and power saving support according to the service request, the extension function unit 131 is added as needed when it is needed, and deleted as needed when it is no longer needed. However, it may be replaced or changed according to the change.

It is desirable that the device-independent API 22 is provided in advance in the basic function unit 132, assuming an extended function unit 131 to be added later. However, if necessary, the device-independent API 22, the device-independent API 27, and other devices are not used. It may be added or deleted in a form that suppresses the modification of the dependent application unit 130.

(4th example of architecture)
FIG. 6 is a diagram showing a fourth example of the architecture of the communication device. The difference between the fourth example of the architecture and the third example of the architecture is that the communication device includes the device-dependent application unit 150 under the basic function unit 132. As described above, the communication device of the fourth example of the architecture has an effect that the configuration of the basic function unit 132 can be simplified by providing the device-dependent application unit 150.

The communication device shown in FIG. 6 includes a device-dependent unit 110 and a device-independent application unit 130. The device-dependent section 110 includes a hardware section 111 (PHY) and a hardware section 112 (MAC), and a hardware section 111 (PHY) and a hardware section 112 (MAC), which depend on a compliant standard or a device manufacturing vendor. It has a software unit 113 such as a driver and firmware to be driven, and a device-dependent application unit 150 that drives at least a part of the device-dependent unit 110. The device-independent application unit 130 uses a driver that hides the difference between the portable IF and the hardware unit 111 (PHY) and the hardware unit 112 (MAC) and the device-dependent software, or the portable IF and the device-dependent application. It is a general-purpose device-independent application that executes device-independent processing via the unit 150. The basic function unit 132 in the device-independent application unit 130 and the device-dependent application unit 150 in the device-dependent unit 110 are connected via the device-independent API 27. The device-dependent application unit 150 and the other functional units of the device-dependent unit 110 are connected via the device-dependent API 24.

In the basic function unit 132 in the device-independent application unit 130, the basic function unit 132 performs input / output with the hardware and the extended function unit 131 instead of the middleware unit 120. The basic function unit 132 may include a management / control agent unit 133 (see FIGS. 3 and 4) that receives communication from the EMS 140, and the extension function unit 131 includes a management / control agent unit 133. You may.

The basic function unit 132 inputs / outputs via the expansion function unit 131 and the device-independent API 22 (expansion IF), and the OAM unit, driver, firmware, hardware unit 111 (PHY), and hardware unit of the device-dependent unit 110. Input / output via 112 (MAC), the driver of the device-dependent unit 110 that hides the difference between the device-independent API 22 (porting IF) and the device-dependent unit 110, or the device-dependent application unit 150 and the device-independent API 27. ..

The basic function unit 132 inputs as it is or in a predetermined format as in the middleware unit 120 shown in FIG. Similar to the third example of the architecture, the basic function unit 132 may include the management / control agent unit 133 corresponding to the communication from the EMS 140, or the management / control agent unit 133 as the extension function unit 131. You may prepare.

The device-independent application unit 130 includes, for example, extended function units 131-1 to 131-3 and basic function units 132. The device-independent application unit 130 does not have to include either the extended function unit 131 or the basic function unit 132, as in the third example of the architecture. The device-independent application unit 130 may further include functional units other than the extended function unit 131 and the basic function unit 132, as in the third example of the architecture.

It is preferable that the extension function unit 131 can be added, deleted, replaced or changed independently of each other without affecting other functions, as in the third example of the architecture. A part of the basic function unit 132 may be replaced by the device-dependent application unit 150. The device-dependent application unit 150 inputs / outputs information directly from the basic function unit 132, but even if the information is input / output to / from the EMS 140 without going through the basic function unit 132 as it is or after a predetermined conversion. Good.

Similar to the first example of the architecture shown in FIG. 3, it is desirable that the device-independent APIs 22 and 27 are provided in advance in the basic function unit 132, assuming an extended function unit 131 to be added later, but the device-independent API 22 , Device-independent API 27, other device-independent application unit 130, device-dependent application unit 150, or device-dependent API 24 may be added or deleted as necessary in a form of suppressing modification.

(5th example of architecture)
The upper right figure of FIG. 7 is a diagram showing a fifth example of the architecture. The lower right figure of FIG. 7 corresponds to the first to fourth examples of the architecture. The figure shows a case where the communication device is an OLT. The fifth example of the architecture is a function cloud that implements (cloud) the OLT function on the external hardware and makes use of the existing / commercial OLT hardware to prepare the function addition / change according to the service. It is suitable for taking a cloud computing approach.

In this example, the communication device consists of existing / commercial hardware and external hardware. For example, the existing / commercial hardware is a non-general-purpose device-dependent section 110 that depends on the device, and a middleware section 121 that hides the difference between hardware and software on the external hardware and a general-purpose section whose operation does not depend on the device. The device-independent application unit 130 is provided. Therefore, the device-dependent section (vendor-dependent section) below the middleware in the figure is a functional section that depends on the standard to which the device of the communication device conforms and the manufacturing vendor of the device. Further, the device-independent application unit 130 is a functional unit that does not depend on the standard to which the device of the communication device conforms or the manufacturing vendor of the device.

The middleware unit 121 and the device-independent application unit 130 are connected via a device-independent API, which is a device-independent input / output IF. For example, the software unit, OAM, hardware unit (PHY) and hardware unit (MAC) of the device-dependent unit 110, and the middleware unit 121 on the external hardware are device-dependent input / output IFs that depend on the device. It is connected via device-to-device connection between API and existing / commercial hardware and external hardware.

In this architecture, the device-independent application unit 130 facilitates the flexible and quick addition of the extended function unit (unique function unit), and can provide the communication service in a timely manner. Here, the device-dependent unit 110 may be maintenance operation, access control, physical layer processing, and optical modular as shown in FIG. 7, and depends on the configuration of the device itself.

For example, the device-dependent unit 110 or the device-independent application unit 130 is designated as a device-dependent unit 110 or a device-independent application unit 130, giving priority to a function having a high update frequency such as DBA for improving main signal priority processing and line utilization efficiency or a function contributing to communication service differentiation. You may decide. Further, the device-independent application unit 130 may be used because the difference is small with respect to at least one of the standard, generation, method, system, device type, and manufacturing vendor to which the device to be shared conforms.

Any of the compliant standards, generations, methods, systems, equipment types, manufacturing vendor features, even if it is not optimal for at least one of the compliant standards, generations, methods, systems, equipment types, and manufacturing vendors. In order to generalize the above, a common IF for executing the function may be used. The common IF may include IFs and parameters that are not used in any of the standards, generations, methods, systems, device types, and manufacturing vendors to which the device-dependent unit 110 conforms.

A conversion function unit that converts IFs, parameters, etc. to at least one of the middleware unit 121, the driver of the device-dependent unit 110, and the device-dependent application unit 150 (vendor-dependent application unit) so as to correspond to the device-dependent unit 110. Alternatively, it may be further provided with a functional unit that automatically sets in response to insufficient IFs, parameters, and the like.

The device-dependent unit 110 includes a hardware unit and a software unit. The software section executes device-dependent drivers, firmware, applications, and the like.

The device-dependent unit 110 may not include a PMD connected to a physical medium, a MAC, a PMA for serializing data, and a part of PCS or PHY which is a part for encoding data. For example, it may have only optical-related functions without providing low-level signal processing such as modulation / demodulation signal processing, forward error correction (FEC), code decoding processing, and encryption processing.

The device-independent application unit 130 is, for example, a management / control agent unit 133 that acquires data from EMS, an extended function unit 131-1 to 131-3, and a basic function unit 132. Hereinafter, matters common to the extended function units 131-1 to 131-3 will be referred to as "extended function unit 131" by omitting a part of the reference numerals. EMS is, for example, a controller that controls network elements. The device-independent application unit 130 may not include any of the management / control agent unit 133, the extended function unit 131, and the basic function unit 132.

The device-independent application unit 130 may further include configurations other than the management / control agent unit 133, the extended function unit 131, and the basic function unit 132. For example, when the extended function unit 131 is unnecessary, the device-independent application unit 130 does not have to include the extended function unit 131. Further, the device-independent application unit 130 may include one or more extended function units 131.

It is preferable that the extension function unit 131 can be added, deleted, replaced or changed independently without unnecessarily affecting other functions. For example, the extension function unit 131 may be added, deleted, replaced, or changed as appropriate when, for example, a multicast service or an extension function unit 131 that executes power saving measures is required according to a service request. ..

The basic function unit 132 may be included in the device-independent application unit 130 as a part of the extension function unit 131, or may be replaced by a function unit lower than the middleware unit 121. When the extended function unit 131 includes the basic function unit 132, the device-independent application unit 130 does not have to include the basic function unit 132. When a functional unit lower than the middleware unit 121 replaces the basic function unit 132, the device-independent application unit 130 does not have to include the basic function unit 132. When the extended function unit 131 includes the basic function unit 132 and the function unit lower than the middleware unit 120 substitutes for the basic function unit 132, the device-independent application unit 130 does not have to include the basic function unit 132.

When the management / control agent unit 133 does not receive communication from the EMS 140 and automatically sets according to a predetermined setting, the management / control agent unit 133 does not have to input / output with the EMS 140. Further, when the management / control agent unit 133 does not have the management setting function and the other device-independent application unit 130, the basic function unit 132, or the device-dependent unit 110 has the management setting function, the device-independent application unit 130 The management / control agent unit 133 may not be provided.

Information may be directly input / output between the EMS 140 and the device-independent application unit 130. Further, the device-dependent unit 110 does not have to include the NE management / control unit 115 and the IF of the NE management / control unit 115.

The basic function unit 132 may be included in the device-independent application unit 130 as a part of the extension function unit 131, or may be replaced by a lower function unit of the middleware unit 120. When the extended function unit 131 includes the basic function unit 132, or when the lower function unit of the middleware unit 120 replaces the basic function unit 132 or is a combination thereof, the device-independent application unit 130 is the basic function unit. 132 may not be included. Further, a part of the basic function unit 132 may be replaced by the device-dependent application unit 150 of the lower function unit of the middleware unit 120.

When the management / control agent unit 133 automatically sets according to a predetermined setting, it is not necessary to input / output information to / from the EMS 140. Further, when the management / control agent unit 133 does not have the management setting function and the other device-independent application unit 130, the basic function unit 132, or the device-dependent unit 110 has the management setting function, the device-independent application unit 130 manages. -The control agent unit 133 does not have to be provided. Information may be directly input / output between the EMS 140 and the device-independent application unit 130.

An example of input / output between the device-independent application unit 130 and the device-dependent unit 110 is as follows. For example, the DBA application unit and the protection application unit input / output information to and from the embedded OAM engine of the TC layer. The DWBA application and the ONU registration authentication application unit input / output information to and from the PLOAM engine of the TC layer. The power saving application unit inputs / outputs information to and from the OMCI and the L2 main signal processing function unit (L2 function unit). The MLD proxy application unit inputs and outputs information to and from the L2 function unit. The low-speed monitoring application (OMCI) inputs and outputs information to and from OMCI. The OMCI and L2 functional units operate the XGEM framer and encryption. Here, the DWBA and the DBA may be separate, integrated, or combined. For example, the management / control agent unit 133 is an application unit of the maintenance operation function, and inputs / outputs information to and from EMS140, which is an NE controller or the like for the NE management / control unit 115.

The device-independent application unit 130 describes the device vendor, method, device type, device generation, for example, ITU-T G.M. TWDM-PON conforming to the 989 series and ITU-T G. XG-PON conforming to the 987 series and ITU-T G. G-PON conforming to the 984 series and ITU-T G. It is an application that operates regardless of any of the 983 series compliant BPON. The device-independent application unit 130 differs in device vendor, method, device type, device generation, for example, 10GE-PON conforming to IEEE802.3av and IEEE1904.1, and GE-PON conforming to IEEE802.3ah. It is an application that works regardless of.

As the application of the extended function unit 131, only the application for driving the functions prepared for some vendors, methods, types, and generations and the devices of some vendors, methods, types, and generations via the device-independent API 21. It may include an app that drives the features provided for.

The management / control agent unit 133 inputs / outputs to and from the EMS 140 and the middleware unit 120. The middleware unit 120 inputs / outputs NE management information and control information to / from the NE management / control unit 115. The NE management / control unit 115 may directly send / receive NE management information and control information to / from the EMS 140 without going through the middleware unit 120, or may send / receive NE management information and control information via the management / control agent unit 133. You may send and receive.

The middleware unit 120 inputs / outputs information via the device-independent application unit 130 and the device-independent API 21. The middleware unit 120 inputs / outputs information to / from the OAM unit 114 of the device-dependent unit 110, the driver, the firmware, the hardware unit 111 (PHY), or the hardware unit 112 (MAC) via the device-dependent API 23. The middleware unit 120 outputs the input information as it is or in a predetermined format. For example, if the output destination is each part of the device-independent application unit 130, the middleware unit 120 converts the information into the input format of each part of the device-independent API 21. If the output destination is the OAM unit 114 of the device-dependent unit 110, the driver, the firmware, the hardware unit 111 (PHY) or the hardware unit 112 (MAC), the middleware unit 120 is the device-dependent API 23 in the form of input to each. After converting to the format, or after terminating and performing the predetermined processing, the information is transmitted to the output destination.

At the time of input, the middleware unit 120 deletes unnecessary input information at each input destination, and if there is insufficient information, it can collect and supplement it via another device-independent API 21 or device-dependent API 23. desirable. Further, when inputting to the middleware unit 120, it may be broadcast or multicast to broadcast to a related application or the like.

The middleware unit 120 and the device-dependent unit 110 are illustrated as a single unit, but each may be composed of a plurality of units. When the hardware of the device-dependent unit 110 includes a plurality of processors, the middleware unit 120 may input / output across the processors and hardware by using interprocessor communication or the like. The device-independent application units 130 and the device-independent application units 130 may be arranged as an execution program such as DLL in the user space on a single processor, or arranged in the user space on a plurality of processors. You may.

Further, the device-independent application unit 130 may be arranged in the kernel space after securing input / output IFs such as API, or may be arranged together with the middleware unit 120 having an IF that can be independently replaced with firmware or the like. Alternatively, it may be incorporated into firmware or the like and recompiled. The user space and kernel space may be any combination for each device-independent application unit 130.

The device-independent application unit 130 corresponding to the same function may be implemented in both the user space and the kernel space. In this case, for example, it may be switched and one of them may be selected, both may be processed in cooperation, or the actual processing may be performed by only one of them. The same applies to the software of the device-dependent unit 110.

Desirably, the more high-speed processing such as main signal processing, DBA processing, and low-layer signal processing is required, the more there is a trade-off with the immediacy of expandability / replacement, but high-speed processing with less overhead is expected. It is desirable to incorporate it in the kernel space or firmware. The processor in which the device-dependent application unit 150 is arranged is also the user space of the processor that performs the actual processing or a processor in the vicinity thereof from the viewpoint of the influence on other programs due to the limitation of the bus and speed due to the communication between the processors and the occupation of the communication path. It is desirable to place it in the kernel space or on the firmware. However, in order to reduce the capacity of the processor performing the actual processing or a processor in the vicinity thereof, the communication cost due to the inter-processor communication increases, but the processing may be performed by a remote processor.

It is desirable that the device-independent API 21 is provided in the middleware unit 120 in advance assuming the extended function unit 131 to be added, but it is necessary in a form of suppressing modification of the device-dependent API 23 and other device-independent application units 130. It may be added or deleted accordingly.

The sixth example of the architecture is the hardware unit 111 (PHY) and the hardware unit 112 (MAC), and the hardware unit 111 (PHY) and the hardware, which depend on the standard or the equipment manufacturing vendor that conforms as the equipment-dependent unit 110. It includes a software unit 113 such as a driver and firmware that drives the unit 112 (MAC), and a device-dependent application unit 150 that drives at least a part of the device-dependent unit 110.

The device-dependent application unit 150 and the device-dependent unit 110 are connected via the device-dependent API 24. The device-dependent application unit 150 may include a management / control agent unit 133 that receives communication from the EMS 140. The device-dependent API 24 may be added or deleted as necessary in a form that suppresses modification of the device-dependent application unit 150 and the device-dependent API 24.

The configuration of the communication device shown in the first to sixth examples of the architecture of the communication device is described on the premise of the IEEE of the PON conforming to the ITU-T recommendation such as TWDM-PON, but it is an ONU. It may be either an OLT or an ONU of an PON conforming to the ITU-T recommendation other than TWDM-PON, or may be an IEEE standard compliant PON such as GE-PON and 10GE-PON, and TC. The same applies if the layer or PMD layer is read as the corresponding layer.

Hereinafter, TWDM-PON is a PON multicast function, a power saving control function, a frequency / time synchronization function, a protection function, a maintenance operation function, an L2 main signal processing function, a PON access control function, and a PON main signal.

For example, in addition to the configuration in which the transmission / reception unit 11 for transmitting / receiving optical signals of different wavelengths (λA to λN) is connected to the same switch unit 12, the transmission / reception unit 11 for transmitting / receiving optical signals of the same wavelength is the same switch. It may be connected to the unit 12, or at least a part of the transmission / reception units 11 for transmitting / receiving optical signals having different wavelengths (λA to λN) are connected to the same switch unit 12.

As an example of the division of functions, the processing may be performed by the application except for the hardware Config, and the software and setting data may be processed by the application on the external server 16 of FIG. 8 without being held by the ONU or OLT. It can also be realized by unifying commands and defining sequences.

FIG. 15 is a diagram showing a second example of the configuration of the function of the maintenance / operation function unit 330. The processes constituting the functions of the maintenance / operation function unit 330 include device status monitoring (CPU / memory / power supply / switching), traffic monitoring, alarm monitoring (ONU abnormality, OLT abnormality), and test (loopback).

FIG. 19 is a diagram showing an example of a functional configuration of the frequency / time synchronization function unit 370. The OLT subordinately synchronizes its real-time clock (RTC) to a higher-level device by using SyncE (Synchrous Ethernet (registered trademark)) (for frequency synchronization) and IEEE 1588v2 (time synchronization).

As an example of the division of functions, it is also possible to perform processing by the application except for hardware switching trigger detection and switching processing such as failure detection. If the EMS side is instructed (from) when the switching trigger is detected without setting the redundant path in advance, it depends on the device.

The eight main functions may be provided as needed. For example, only the PON main signal processing function, the PON access control function, the L2 main signal processing function, and the maintenance operation function may be provided, or other functions may be provided. You may. In addition, the evaluation of whether or not each function can be softened is an example on the premise that the processing capacity of OLT expected in 2018 and the application of the soft switch are not assumed. It may be changed as appropriate assuming the assumed processing capacity and application of the soft switch. The function may or may not be softened. The internal configuration of each function may be another configuration as long as the same function can be realized.

The main softening area is the algorithm included in the eight main functions. The function in the software area is the device-independent application unit 130 on the device-independent APIs 21 and 22. For example, the algorithms in the ONU registration or authentication function, the DWBA function, the setting / management / monitoring control function, and the power saving control function that contribute to the differentiation service are treated as the extension function unit 131 in the device-independent application unit 130. The MLD proxy app includes a multicast function.

The extended function unit 131 is used as the extended function unit 131 according to the importance of updating the function, realizing the original specifications, etc. in the application. Those with low update frequency or low demand for realization of original specifications are middleware units 120 other than basic function unit 132 and device-independent application unit 130, device-dependent software, hardware unit 111 (PHY), and hardware unit 112 ( MAC) is preferable. In particular, it is preferable to leave the limited functions due to the processing capacity of the software as the hardware unit 111 (PHY) and the hardware unit 112 (MAC). For example, priority processing of main signals and functions such as DBA that improve line utilization efficiency or contribute to service differentiation, and management that is closely related to the operator's business flow and requires unique specifications for each operator. From the control function to the extended function unit 131.

FIG. 22 is a diagram showing a flow of signals / information between functional units in a communication device. The figure shows the flow of signals / information between functional units in a communication device, focusing on In / Out of OLT. As shown in the figure, the OLT as a communication device is composed of an API lower processing entity (FASA platform) and an application (FASA application).

The API lower processing entity is the MPCP / DBA processing entity whose OLT input / output target is a transmission instruction and reception notification for MPCP transmission / reception, the OAM processing entity whose OLT input / output target is OAM transmission / reception, and the OLT input / output target is ONU authentication transmission / reception. A certain ONU authentication processing entity, an MLD / IGMP processing entity whose OLT input / output target is MLD / IGMP transmission / reception, another protocol processing entity whose OLT input / output target is other protocol transmission / reception, and main signal processing such as bridge / encryption for OLT input / output It is illustrated by the main signal setting processing entity which is the setting and reference / state acquisition for, and the device management processing entity whose OLT input / output target is OLT hardware, IF, OS, or the like. Here, it is desirable that the transmission instruction and reception notification for MPCP transmission / reception are something like send_frame (* raw_frame); assuming that the driver is directly hit.
In the figure, DBA, ONU management, line management, multicast, EtherOAM, redundancy, device management, alarm management, Netconf agent, and application management are illustrated as applications.

The In / Out of the OLT is roughly classified into three types: input / output to the ONU, setting / notification to the OLT itself, and input / output to the EMS. Seen from the application on the upper side of the API, the lower processing part of the API is (a) easier (conveniently) and (b) common (between multiple types) than the processing such as direct tapping of the driver. , (C) It is desirable that there is a processing entity that conveniently processes it.

The functional division of the API lower processing entity is illustrated below. The app has a corresponding process. The functional division between the API lower processing entity and the application may be any of the following or other than that, and may differ depending on the actual processing.

(0) Message through: A message is passed through on the upper side of the API and the ONU / upper NW.

(1) Framing: The message is unframed, decomposed or processed into elements as necessary, and provided to the upper side of the API. Information is passed from the upper part of the API to the lower part of the API. The API lower processing entity performs framing. Since the API is highly dependent on each protocol, it may be included in the device-dependent application section. It is desirable that fixed parameters (type values, etc.) are set and retained from the top of the API at the time of initialization. The setting parameter returns to the reference from the top of the API.

(2) Automatic response: The processing entity is responsible for sending and receiving messages that do not require judgment, such as periodic transmission and fixed response. It is desirable that the operation is set in advance from the upper part of the API. For example, response cycle. Notify the result only when notification to the upper part of API is required.

(3) Autonomous judgment: The processing entity is also responsible for processing that involves judgment. Policy settings are made in advance from the top of the API.

This figure is described in accordance with IEEE-compliant 10GEPON, but the same applies to ITU-T and other compliant devices if the corresponding functions and processes are read. In addition, the functions and processing conditions are examples, and may be added, deleted, replaced, or changed as appropriate according to the conditions.

Further, regardless of the above classification, it may be arranged on any one of Cont, OSU, SW, or a plurality of combinations thereof. Further, the device setting IF in FIG. 23 may be a part of the EMS-IF, or may be equivalent to the device-dependent API 25 in FIG. Further, although the processing of the application is performed on the CPU, some or all of the processing may be performed on an alternative device having a processing function, for example, a processor other than the CPU, such as a GPU, NPU, DSP, or an FPGA. The same applies to other embodiments.

FIG. 24 is an example in which the application is arranged on a server or the like instead of the CPU package. The application is processed on a server or the like, and the processing result of the application arrives at the OLT after being transmitted on the transmission line in a format that can be transmitted on the transmission line such as an Ethernet (registered trademark) frame. Here, as the format that can be transmitted on the transmission line, a frame other than the Ethernet (registered trademark) frame or transmission of TDM or the like may be used. Further, the processing result is transmitted via a converter (Conv. In FIG. 24), but if the OSU, SW, or λ card can receive the processing result of the application without going through the converter, the conversion is performed. No machine is needed. The server or the like may correspond to the external server 16 of FIG. 8 or the proxy unit 15.

The CPU of FIG. 25 may be the CPU package of FIG. 24, a location having processing capacity on or other than the server of FIG. 24, or a combination thereof. The MAC of the OSU assumes a dedicated LSI for OSU processing, but a general-purpose LSI may be used as long as equivalent processing is possible.

FIG. 26 shows the processing of the application of the eight main functions and G.M. It is a figure which shows the example of correspondence with 989.3 function. The DBA application, the DWBA application, the ONU registration authentication application, the power saving application, the protection, and the high-speed monitoring application are connected to the TWDM TC function unit (TWDM TC artifacts) of the TWDM TC layer.

That is, FIG. 27 shows a process in which PLOAM and OMCI acquire the corresponding data from the control unit 14 or the proxy unit 15 of FIG. 8 or the external server 16 via the SW in addition to the user data.

The user data client (User Data Client) acquires data from the user data adapter (User Data Adapter) via the switch unit (SW). The user data client sends data to the user data adapter via the switch section. The OMCI client (OMCI Client) of the CPU acquires data from the OMCI adapter (OMCI Adapter) via the switch unit. The OMCI client transmits data to the OMCI adapter via the switch unit.

The TWDM TC function unit (TWDM TC functions) of the TWDM TC layer acquires data from the embedded header area (embedded header fields) via the switch unit. The TWDM TC function unit of the TWDM TC layer transmits data to the embedded header area via the switch unit.

In the examples of FIGS. 3 and 4, the softened area is the basic function unit 132, the management / control agent unit 133, the extended function unit 131, and the middleware unit 120, but the softened area is the service adaptation (encryption). , Fragment processing, GEM framing / XGEM framing, PHY adaptation FEC, scrambling, synchronous block generation / extraction, GTC (GPON Forward Generations) framing, PHY framing, SP conversion, coding method may also be targeted. An example of implementing the software function of the architecture and an example of function deployment corresponding to the hardware section 111 (PHY) and the hardware section 112 (MAC) will be described. The function deployment is softened to, for example, a network device or an external server. It has a function.

Assume an OLT including a plurality of OSUs, switches, information processing units, and control units. Each OSU has a different transmitter / receiver for each wavelength. In this case, the middleware unit 120 is mounted on each OSU and the switch, and the software area such as the device-independent application unit 130 is mounted on the information processing unit.

The information processing unit, that is, the CPU executes the device-independent application unit 130. The device-independent application unit 130 includes an extended function unit 131 for the OSU, an extended function unit 131 for the switch, and an extended function unit 131 for the control unit. The extension function unit 131 for OSU is, for example, a power saving application, a protection application, a DBA application, and an ONU registration authentication application. The extended function unit 131 for the switch is, for example, an MLD proxy application. The extension function unit 131 for the control unit is, for example, a low-speed monitoring application (OMCI), a low-speed monitoring application (EMS-IF), and a setting / management application. The EMS is, for example, an OSS (Operation Support System).

In the case of the DBA application, the middleware unit 120 shown in FIGS. 3 and 4 or the basic function unit 132 shown in FIGS. 5 and 6 is an embedded engine that is a hardware unit 111 (PHY) and a hardware unit 112 (MAC) of the TC layer. The OAM engine (Embedded OAM Engine) is operated. Then, the transmission / reception unit, which is the hardware unit 111 (PHY) and the hardware unit 112 (MAC) of the PMD layer, receives according to the DBA application. If the transmitter / receiver receives an uplink signal that does not follow the DBA, it may not follow the DBA application.

The information processing unit is not limited to these softening functions, and may have other softening functions. The hardware unit 111 (PHY) and the hardware unit 112 (MAC) are not limited to the transmission / reception unit, the OSU, the switch, the control unit, and the information processing unit. For example, the information processing unit may be included in the transmission / reception unit, the OSU, the switch, and the control unit. Further, as shown in FIG. 8, a proxy unit or an external server that processes signals input / output to / from the switch may be provided on the NNI (Network-Network Interface) side of the switch. The external server 16 may be an information processing function called a so-called cloud such as a data center provided with a plurality of devices.

Each function may be appropriately arranged according to the demand for processing capacity and processing delay. Further, the OSU may be provided with a switch unit 12 or a switch unit 13, or may be provided with a switch (switch unit 12 when the switch unit 13 is provided) separately from the switch. It is desirable that the functions of the switches are appropriately shared between the switch unit 12 and the switch unit 13 according to the processing capacity of the switch without overlapping, but they may overlap.

The place where the software function is deployed is not limited to the information processing unit, and may be placed in a place where a plurality of arithmetic operations can be performed. For example, the places where the software function is deployed are other than the transmission / reception unit, OSU switch, OSU switch, OLT control unit, OLT switch, OLT information processing unit, OLT switch, control unit, and information processing unit. It may be either a proxy unit that processes signals input / output to / from the switch on the NNI side of the switch, or a processing device such as an external server.

Further, the arrangement of the softening functions may be for each softening function, or may be a part of the softening functions obtained by dividing a single softening function. For example, other parts of the transmission / reception unit other than the transmission / reception unit, such as the OSU switch, the OSU transmission / reception unit and other than the switch, the OLT switch, the OLT control unit, the OLT information processing unit, and the rest of the OLT. It may be deployed somewhere outside the OLT, such as a proxy unit or an external server on the main signal path, or a combination of a plurality of deployment locations. Other than the PON termination processing deployment location, for example, the OSU transmission / reception unit, OSU switch, OSU transmission / reception unit and other than the switch, OLT switch, OLT control unit, OLT information processing unit , Other than OLT, it may be deployed to somewhere such as a proxy unit, an external server, etc. on the main signal path outside the OLT, or to a combination of a plurality of deployment locations.

It may be deployed to somewhere such as a proxy unit or an external server on the main signal path outside of the above, or to a combination of a plurality of deployment locations. Items related to OLT switches other than OLT switches, such as transmission / reception unit, OSU switch, OSU transmission / reception unit and other than switch, OLT control unit, OLT information processing unit, OLT other than OLT. It may be deployed to somewhere such as a proxy unit, an external server, etc. on the main signal path outside of the above, or to a combination of a plurality of deployment locations.

Further, the location where the software function is deployed may be appropriately changed according to the deployment status of the extension function unit 131, the computing capacity of the computing location, the computing load, the power consumption, and the like.

The main functions related to the main signal processing of the OLT and the relationships between the functions will be described. Transfer the OLT function to the switch. A PON main signal processing function that performs PON section processing such as a PHY adaptation function, a framing function, and a service adaptation function is provided in the transmission / reception unit. PON access control functions such as ONU registration or authentication function, DBA control function, and DWA function are provided in the information processing unit. The switch is provided with L2 main signal processing functions such as VLAN control used in framing, priority control in the pre-stage of shaper, max or demax (Max / DMux) and queue (Queue), and shaper in front of framing.

Deploy the multicast function such as the copy function in the previous stage of the shaper and the MLD proxy used for copying to the switch. In this way, by deploying the PON main signal processing function and the PON access control function deployed in the PON to the switch, the PON basic function unit is reduced. In particular, the L2 main signal processing preferably avoids duplication and is deployed in the switch.

It should be noted that the switch functions are illustrated on the premise that Classifier (classifier), Modifier (modifier), Policer / Shaper (poliser / shaper), CrossConnect (cross connect), Queue (queue), and Scheduler (scheduler) are provided in this order. However, it may be changed as appropriate. For example, in the uplink direction, if processing is not performed within the bandwidth allocation unit, the input from the ONU is PON by removing the preamble and burst overhead for burst transmission, decapsulating the frame, and removing the LLID. Is terminated only, and all the functions of Classifier, Modifier, Policer / Shaper, Cross Connect, Queue, and Scheduler may be performed by the switch, or only Modifier, Cross Connect, Queue, and Scheduler may be performed by the switch.

Further, if a VID or the like describing the path or the like after the PON termination is given by the ONU, Cross Connect, Queue, and Scheduler may be used. If the upper network can be regarded as a single path, Queue and Scheduler may be used. Further, if the DBA is performed so that the frames do not collide with the Cross Connect, the classifier, the modifier, the Polar / Shaper, and the Cross Connect can be obtained. Furthermore, if processing is not performed in the bandwidth allocation unit in the upstream direction, the input from the ONU is removed from the preamble and burst overhead for burst transmission, the frame is decapsulated, and the LLID is removed to PON. If only the termination is performed and a VID or the like describing the path or the like after the PON termination is given by the ONU, only the Cross Connect can be used.

Further, in Classifier, Modifier, Policer / Sharper, CrossConnect, Queue, and Scheduler, Classifer, Policer / Shaper, Modifier, CrossConnect, Queue, and Queue may be placed in front of the quer. It may be a Modifier, Queue, Policer / Sharper, CrossConnect, Scheduler, or it may be a Classiffier, Queue, Collector / Queue, Modifier, CrossConnect, Scheduler. Considering the burst transmission of PON, unnecessary police / shaping due to the burst property caused by multiplexing priority traffic such as multicast, and the reception of leveled traffic on the receiving side, the police / shaper It is desirable to execute the processing by Police / Shaping after placing Queue in the previous stage and leveling it.

At the time of state transition to a specific state, the subject of the sleep operation or the like stores the instruction of the subject of the sleep operation or the like (the device provided in the communication device) in an external state independent of the subject of the sleep operation or the like. It is possible to inherit the operation. The specific state is, for example, a sleep state, a switching state of an operating communication device, a user accommodation switching state, and a multicast state. Since the information is held outside the communication device, it is possible to prevent the inheritance of the sleep operation and the like from being lost when switching to another communication device. The communication device can ensure the inheritance of the information held by the device.

Further, by diverting a normal general-purpose or softwareized switch as an execution unit, it is possible to realize an OLT capable of inexpensive, flexible and quick function addition of a general-purpose or softwareized switch.
