Cross-board processing method, apparatus and system of service messages

Abstract

The invention provides a cross-board processing method, apparatus and system of service messages. A main control board is connected with one or more service line cards; the main control board is provided with multiple virtual service ports, which are in one-to-one correspondence with the physical service ports of the service line cards and share the same port index; service messages sent by the service line cards are received by corresponding virtual service ports; forwarding query processing is performed on the service messages to obtain the port indexes of the virtual service ports corresponding to the destination addresses of the service messages; and the service messages are sent to the corresponding service line cards according to the port indexes corresponding to the destination addresses, so that the service line cards send the service messages through the physical service ports corresponding to the virtual service ports. By adoption of the cross-board processing method, apparatus and system, the logic complexity of the main control board software module and the coupling of the software modules of the main control board and the service line cards are reduced, and the robustness of the whole system is improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method, device and system for cross-board processing of service messages. Background technique [0002] In the field of communications, rack-mounted routers and switch systems that meet the distributed architecture are generally composed of main control boards and service line cards. In traditional technologies, cross-board processing of service packets is relatively complicated. The central processor of the main control board includes a protocol calculation processing unit, a slow forwarding unit, etc.; each unit needs to process the receiving and sending of service messages independently, that is, which port of the line card the processing message is sent and received from . This processing method leads to complex implementation logic of the software module of the main control board, and the high coupling between the software modules of the main control boa...

AI Technical Summary

Problems solved by technology

This processing method leads to complex implementation logic of the software module of the main control board, and the high coupling between the software modules of the main control board and the service line card, which makes the whole system less robust.
