ONU channel management method and system based on gRPC

Abstract

The invention discloses an ONU channel management method and system based on gRPC. The management method comprises the steps that a virtual OMCI module and an OLT establish a traditional channel; a main control panel and a service line card establish a master-slave channel; the service line card and an ONU establish a PON channel; the virtual OMCI module and a version server both establish data channels with the ONU; the virtual OMCI module determines the function type of a management message; if the management message is a performance statistical message or an upgrading message, the management message is sent to the ONU through a data channel; and if the management message is a control message, the management message is sent to a main control panel of the OLT through a traditional channel, the main control panel sends the management message to the service line card through the master-slave channel, and the service line card sends the management message to the ONU through a PON channel. In the method, two channels are used to manage the ONU according to different service characteristics, and the requirements of a virtual OLT system on different service processing efficiencies are met.

Description

technical field [0001] The present invention belongs to the field of optical communication, and more specifically relates to a management method and system of a gRPC-based ONU channel. Background technique [0002] In the access network system, the OMCI (ONUM Management and Control Interface, abbreviated as OMCI) module used to manage the ONU (Optical Network Unit, abbreviated as ONU) is located in the OLT (Optical Line Terminal, abbreviated as OLT) equipment. There are differences in the OMCI modules of different manufacturers, so in order to realize the intercommunication between OLT and ONU of different manufacturers, it is necessary to test the OLT and ONU of different manufacturers and modify the software to achieve interoperability. The whole workload is heavy and the technology is complicated. [0003] In the virtual OLT system, the OMCI module will be virtualized, and the virtual OMCI module will manage the ONUs of various manufacturers, so that the problem of inter...

Problems solved by technology

[0005] Aiming at the above defects or improvement needs of the prior art, the present invention provides a management method and system for ONU channels based on gRPC. Different business processing efficiency requirements, the management message of the performance statistics function is transmitted through the data channel, which can greatly reduce the occupancy of the master-slave channel of the OLT, and reduce the utilization rate of the processor of the master control panel and business line card, thus When the message passes through different channels, there will be multiple unpacking and grouping processes, which will not only occupy the processor resources of the main control panel and service line card, but also occupy the master-slave channel. When the message is very long or the number is large, The communication rate will drop a lot, and the processor occupancy rate of the main control panel and service line card will also be high, resulting in a technical problem of system efficiency drop
