After the entity OLT receives the IP of the virtual OMCI module, the master control disk of the entity OLT actively initiates a connection to the virtual OMCI module, and establishes a gRPC (generic Remote Procedure Call, abbreviated as gRPC) channel, where the gRPC channel is used to transmit a general OMCI message. The network manager communicates with the virtual OMCI module through the management and control module and manages the ONU, the main control disk receives the gPC packet sent by the virtual OMCI module, analyzes the OMCI message, adds a main and auxiliary protocol message header, sends the data packet to the service line card through a main and auxiliary channel of the main control disk and the service line card, and sends the data packet to the ONU through the PON channel after the service line card analyzes the OMCI message. The message sent from the ONU can also reversely go through the PON channel, the master-slave channel and the gPC channel to transmit the message to the virtual OMCI module.
When the message passes through the different channels, the packet unpacking and packing processes are repeated, not only the processor resources of the master control panel and the service line cards are occupied, but also the master channel and the slave channel are occupied, when the message is very long or the number of the message is very large, the communication rate is greatly reduced, the processor occupancy rates of the master control panel and the service line cards are also very high, and the system efficiency is reduced.

In this embodiment, for different service characteristics, two channels are used to manage the ONUs, so as to implement different functions, respectively, and meet the requirements of the virtual OLT system on different service processing efficiencies. For the common management function, the management message still goes through the master-slave channel to manage the ONU, and the software change is small. The management message with the performance statistics function is transmitted through the data channel without walking a master-slave channel or encoding and decoding by a processor of a master control disk and a service line card, so that the occupation of the master-slave channel of the OLT can be greatly reduced, the utilization rate of the processors of the master control disk and the service line card is reduced, and the number of the ONUs for performing performance statistics by the OLT at the same time can be increased.
The management message of the ONU upgrading function is routed through a data channel, and the data channel is used for connecting and downloading the upgrading file, so that the defect of low efficiency caused by that the upgrading is carried out by using OMCI (operation management interface) and needs to be split into small packets is avoided, the file downloading speed is high, the upgrading time can be shortened, and the number of ONUs which can be simultaneously upgraded by the OLT is increased.
It will be understood by those skilled in the art that the foregoing is only a preferred embodiment of the present invention, and is not intended to limit the invention, and that any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the present invention.
