3) After the vOMCI instance completes the ONU management and control processing request, a response message is generated, the message carries the execution result, and the corresponding ONU identifier of the response message can be determined through the related low-layer mechanism of the prior art. The response message is sent to the ONU management agent subsystem. The ONU management agent subsystem queries the ONU management and control processing task distribution table, finds the corresponding vOLT management and control system identifier or gRPC connection according to the ONU ID, and sends the ONU management and control processing request response message to the vOLT management and control system or its instance through the connection;

4) If the vOMCI instance is recreated in its life cycle or is eliminated when a failure occurs, the vOMCI agent subsystem must update or delete the entry related to the vOMCI instance in the ONU management and control processing task distribution table.

When the vOMCI message broker subsystem on the OLT system equipment side distributes OMCI message requests and responses between the vOMCI subsystem and the OLT system equipment:

1) After the vOMCI instance receives the ONU control request, after generating the OMCI message sequence, it sends the ONU identifier and the OMCI message to the vOMCI message proxy subsystem on the OLT device side through the gRPC connection;

2) After the vOMCI message proxy subsystem on the OLT device side receives the OMCI message request, it queries the connection identifier of the corresponding OLT device network service in the vOMCI message distribution table according to the ONU identifier it carries, and sends it to the OLT device through the connection;

3) After receiving the OMCI request message from the second subsystem, the OLT device forwards the OMCI message to the corresponding ONU device according to the ONU identifier; the OLT device returns the OMCI response message received from the ONU device to the vOMCI on the OLT system device side through the gRPC connection message broker subsystem;
