Example 1:

The embodiment 1 of the invention provides a method for realizing MPM dual-mode service of a 50G PON system, which comprises a method for coexisting 10G EPON ONU and 50G GPON ONU at the same PON port.

Step 120: the main control board card selects 10G EPON ONU and 50G GPON ONU, and pushes the authorization table, the service bandwidth policy and the unified VLAN (Virtual Local Area Network ) service to the service board card according to the requirement, and the service board card takes effect of the local side chip and the remote ONU. In the step, the main control board card selects 10G EPON ONU and 50G GPON ONU, analyzes gemport modes supported by the ONU, pushes the authorization table and the service bandwidth policy. In addition, the main control board card also pushes unified VLAN business, and the business board card takes effect of the local side chip and the remote ONU.

Step 130: the service board adds allocid and gemportid attributes to each VLAN service, and associates each VLAN service according to bandwidth configuration. In this step, when the service board card processes the VLAN service, each VLAN service is added with allocid and gemportid attributes, and each VLAN service is associated one by one according to the bandwidth configuration.

Based on the above steps, the present embodiment can realize coexistence of 10G EPON ONU and 50G GPON ONU at the same PON port.

Specifically, the service bandwidth policy in step 120 of this embodiment specifically includes: judging the PON type of the ONU; for a 50G GPON ONU, determining gemport capacity of the ONU, and if one ONU is supported to be gemport, configuring comprehensive service bandwidth; if one service is supported by gemport, configuring the broadband internet bandwidth; for 10G EPON ONUs, the single-link EPON system uses default channel bandwidth without pushing traffic bandwidth. As shown in fig. 3, the service bandwidth policy specifically includes the following procedure.

Step 121: and judging the ONU PON type.

Step 122: if it is a 50G GPON ONU, step 124 is entered.

Step 123: if it is a 10G EPON ONU, the process proceeds to step 129.

Step 124: determine ONU gemport capabilities.

Step 125: if one ONU is supported gemport, step 127 is entered.

Step 126: if one service is supported gemport, then step 128 is entered.

Step 127: and configuring the comprehensive service bandwidth.

Step 128: and configuring the broadband internet bandwidth.

Step 129: the single link EPON system uses default channel bandwidth without pushing traffic bandwidth.

Based on the above service bandwidth policy, step 120 of this embodiment specifically includes the following processes: the master control board card analyzes the discovery information, selects 50G GPON ONU and 10G EPON ONU, and pushes the authorization table to the service board card according to the requirement; the main control board card pushes the service bandwidth strategy, and for the 50G GPON ONU, if one ONU supports one ONU of gemport, the comprehensive service bandwidth is pushed, allocid and gemportid of the bandwidth are generated by the service board card, and a local side chip DBA is validated, and allocid and gemportid are issued to a far end through an OMCI; if the ONU supports one service, namely gemport ONU, the broadband internet bandwidth is pushed, the service board card generates allocid of the bandwidth, the effective local side chip DBA is issued allocid to the far end through the OMCI, and gemportid of a specific VLAN is distributed in the VLAN service; for 10G EPON ONUs, the single link EPON system uses default channel bandwidth without pushing traffic bandwidth. And then, the master control board card pushes the unified VLAN business, and the business board card takes effect of the local side chip and the remote ONU. In this embodiment, the main control board card pushes unified VLAN traffic, which is the configuration of the assigned port VLAN correlation (VLAN value, VLAN action, whether QINQ is enabled, etc.). A specific process flow of VLAN traffic is described in detail in embodiment 2 with reference to fig. 7. And after the main control board card is pushed successfully, the service board card receives and processes the configuration data. The flow of processing the data by the service board card is as follows: a. the allocid and gemportid of the VLAN business are related one by one according to the ONU bandwidth data and the capacity, and the VLAN business is issued to the ONU through OMCI or OAM; b. and converting the VLAN data of the service layer into driving data, and transmitting the driving data to the driver to finish adding the VLAN of the service to the chip and realize the chip streaming. It should be noted that, in the above process, the main control board card pushes the service bandwidth, and the service board card takes effect of allocid and gemportid of the local side chip DBA configuration and the remote ONU; after the main control board card pushes the VLAN business, the result of processing the VLAN business by the business board card is to configure the flow configuration of the local side chip and send the VLAN business to the remote ONU.

Step 130 of this embodiment specifically includes the following procedures: the service board card processes VLAN services, firstly, each VLAN service is added with allocid and gemportid attributes, allocid which are effective according to bandwidth configuration and gemportid which are necessary are associated one by one, then a chip is used for establishing a stream, and the chip is used for establishing the stream and specifically comprises the following steps: and acquiring all VLAN lists and TUNNEL_ID of ONU port services, converting the VLAN data of the service layer into driving data, transmitting the driving data to a bottom layer driver, and completing the creation of the service flow by the bottom layer. In the 10G EPON ONU, 50G GPON ONU coexistence scene, the resource pool is not repeated for the llid range of EPON system and the gemportid range of GPON system, the llid range of 10G EPON ONU is 1-128, the gemportid range of 50G GPON ONU is 129 to (4095+128), both ranges are set to be unique in the system to ensure coexistence, port number, vlan_old, vlan_new and tuneel_id are unique in the system to avoid resource collision in coexistence scene, when 10G EPON ONU and 50G GPON ONU are under the same port, and VLAN is all the same, it is necessary to distinguish llid range of 10G EPON ONU and gemportid range of 50G GPON ONU. Note that, in each id, GEMPORT is a minimum bearer unit of a service in the GPON standard, and T-CONT is a unit for transmitting uplink data. The service is mapped to GEMPORT according to the mapping rule, and then uplink transmission is carried out in the mapping to T-CONT. GEMPORT can be flexibly mapped into a T-CONT, one GEMPORT can be mapped into a T-CONT, and a plurality of GEMPORT can be mapped into the same T-CONT. allocid is to identify different T-CONT, gemportid is to identify different GEMPROT, tunenl_id is tunnel ID defined by NP chip, abstract, here llid in the case of 10G EPON and gemportid in the case of 50G GPON system. Note that llid and the logical ID in this embodiment are not one entity, llid is a link identifier number specific to the EPON standard (corresponding to the link identifier number in the GPON standard gemportid), and the logical ID is a logical identifier specific to ONU information (corresponding to the link identifier number in the GPON standard physical identifier).

Referring to fig. 4, a flow timing chart of the same PON port coexistence 10G EPON ONU and 50G EPON ONU in this embodiment is illustrated, which includes interaction procedures of 10G EPON ONU1, 50G EPON ONU2, service board card, and main control board card. Firstly, 10G EPON ONU1 sends an SN1 discovery message to a service board card, and 50G GPON ONU2 sends an SN2 discovery message to the service board card; after ONU ADD (10G EPON ONU1 and 50G GPON ONU2 are added) and activation authentication is carried out, switching a state machine, and then 10G EPON ONU1 and 50G GPON ONU2 are activated, wherein the service board card also sends discovery information (including physical SN, physical password, logical ID, OUN PON type, service model and the like) to the main control board card; the main control board card pushes the authorization table to the service board card, selects ONU (optical network Unit) such as 50G GPON, 10G EPON and the like according to the discovery information, and pushes the service bandwidth to the service board card as required; after the service board card matches the authorization and the bandwidth, service bandwidths allocid and gemportid to 50G GPON ONU2 are issued through the OMCI; the main control board card pushes unified VLAN business configuration to the business board card; after VLAN business configuration and stream establishment operation, the business board card sends VLAN business to 10G EPON ONU1 through OAM, sends VLAN business to 50G GPON ONU2 through OMCI, and returns execution result to the main control board card.

In summary, the method for implementing MPM dual-mode service of 50G PON system according to the embodiments of the present invention may implement MPM dual-mode hybrid 50G PON service requirements on the basis of being compatible with a conventional PON application scenario (pure EPON or pure GPON).

In this step, the replacement request includes one or more of physical SN, physical password, logical ID, PON type, service model of new and old ONUs

Step 220: the main control board card de-authorizes the 10G EPON ONU which is offline, authorizes the 50G EPON ONU which is newly online, updates the local authorization table information, then pushes the authorization table, the service bandwidth policy and the unified VLAN service to the service board card, and the service board card takes effect of the local side chip and the remote ONU.

Based on the steps, the embodiment can realize the replacement and upgrading of the 10G EPON ONU to the 50G GPON ONU.

Referring to fig. 7, in this embodiment, in the process of replacing and upgrading a 10G EPON ONU to a 50G EPON ONU, a specific flow of processing VLAN traffic by a service card is as follows.

Step 221: for a 50G GPON ONU, step 223 is entered.

Based on the specific flow of ONU authentication by the service card and the specific flow of VLAN service processing by the service card, step 210 of this embodiment may be specifically expanded into the following processes: the 10G EPON ONU and the 50G GPON ONU have the same logic ID, and after the authorized 10G EPON ONU goes offline, the 50G GPON ONU is newly on line for the first time. In this case, the service board card performs ONU authentication after receiving the online message of the new ONU. If the authentication is the logic ID authentication, acquiring a state object and data of the state object according to the PON number and the physical SN of the ONU, searching a configuration object according to the PON number and the logic ID of the state object, if the configuration object is not on line, returning the authentication to a replacement request, and pushing the physical SN, the physical password and the logic ID of the new and old ONU and the PON type and service model of the ONU to a main control board card as the replacement request. The replacement request includes the physical SN, physical password, logical ID, PON type of ONU, service model, etc. of the new and old ONUs. Note that, in this embodiment, the new ONU refers to a newly-online 50G pon ONU, and the old ONU refers to an offline 10G EPON ONU. In the above-described procedure of the present embodiment, when ONU authentication is performed, only logical ID authentication is processed, and only a replacement request under the authentication is used in engineering application, and if the authentication method is not performed, direct return is not processed. And when judging whether the configuration object is online, if so, not processing the configuration object, and directly returning to the default request.

For step 220 of this embodiment, the following procedure may be specifically extended: the main control board card analyzes the replacement request, firstly, the old ONU is de-authorized, the new ONU is authorized, the local authorization table information is updated, and then the service bandwidth is pushed to the service board card. The service board card firstly de-authorizes the old 10G EPON ONU and clears all resources and memory of the ONU. Then the new 50G GPON ONU is authorized to create a new memory space. The main control board card pushing service bandwidth step specifically comprises the following steps: for a 50G GPON ONU, if the ONU supports one ONU, one ONU of gemport, the comprehensive service bandwidth is pushed, allocid and gemportid of the bandwidth are generated by a service board card, and a local side chip DBA is validated, and allocid and gemportid are issued to a far end through an OMCI; if the ONU supports one service, one gemport ONU, the broadband internet bandwidth is pushed, the service board card generates allocid of the bandwidth, the effective local side chip DBA is issued allocid to the far end through the OMCI, and gemportid of a specific VLAN is distributed in the VLAN service. The master control board card pushes unified VLAN business, and the business board card takes effect of the local side chip and the remote ONU. When the service board card processes VLAN service, for the configuration of remote ONU, firstly judging ONU PON type, for 50G GPON ONU, judging the gemport mode of ONU again, if one ONU is supported to be gemport, acquiring allocid and gemportid of comprehensive service bandwidth, updating allocid attribute and gemportid attribute of VLAN service, and issuing VLAN service with allocid and gemportid to ONU through OMCI; if one service is supported gemport, allocid of broadband internet bandwidth is obtained, and allocid attribute of VLAN service is updated; the increment handles gemport of each service, deletion gemport of service entry reduction, allocation increment gemport of entry increment, and unchanged non-processing of the entry. And finally, the VLAN business with allocid and gemportid is issued to the ONU through the OMCI. After ONU configuration processing is completed, local side data are carried out, all VLAN lists and TUNNEL_ID of ONU port services are obtained, after service layer VLAN data are converted into driving data, a driving interface is called, the transparent transmission service of the ONU is configured, and VLAN service flow (flow) is created by a chip.

Referring to fig. 8, a flow chart illustrating a process of replacing and upgrading a 10G EPON ONU to a 50G EPON ONU in this embodiment includes an offline 10G EPON ONU, a newly-online 50G EPON ONU, a service board card, and a main control board card interaction process. Firstly, an offline 10G EPON ONU sends an offline message to a service board card, and a newly-online 50G EPON ONU sends an SN discovery message to the service board card; after judging that the logic IDs of the two ONUs are consistent, the service board card authorizes the 10G EPON ONUs to go offline, and the authentication result of the 50G GPON ONUs is replacement, and further, the service board card sends a replacement request (comprising the physical SN, the physical password, the logic ID, the ONU PON type, the service model and the like of the new ONU and the old ONU) to the main control board card; the main control board card updates local data, pushes old 10G EPON ONU de-authorization and new 50G GPON ONU authorization information to the service board card, and pushes service bandwidth policies to the service board card according to requirements; the service board card de-authorizes the old 10G EPON ONU, authorizes the new 50G GPON ONU, correspondingly deletes the old 10G EPON ONU, and adds and activates the new 50G GPON ONU; after the main control board card pushes the service bandwidth to the service board card, the service board card generates allocid configuration local side DBA and far-end data, and issues the service bandwidths allocid and gemportid to the newly-online 50G GPON ONU through the OMCI; after the main control board card pushes VLAN business to the business board card, the business board card carries out VLAN business configuration and stream establishment, then sends VLAN business to the newly-on 50G GPON ONU through OMCI, and returns the execution result to the main control board card.

In summary, the embodiment of the invention provides a method for implementing an MPM dual-mode service of a 50G PON system, which can implement a hybrid 50G PON service requirement of an MPM dual-mode on the basis of being compatible with a traditional PON application scenario (pure EPON or pure GPON), and can also meet an ONU on-demand replacement requirement in a smooth upgrade process. And meanwhile, the system has expandability and meets the requirement of higher bandwidth rate in the future. On the other hand, the system fault tolerance and flexibility are improved according to the bandwidth and service model self-adaption of different ONUs.
