Embodiment Construction

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0025] At present, due to the complexity of cross-board processing of business messages by communication devices with a distributed architecture, the robustness of the system is low. Based on this, a business message cross-board processing system and service message The redirection method can be applied to switches, routers and other distributed architecture devices.

Abstract

The present invention provides a service message cross-board processing system and a service message redirection method, wherein the system comprises a main control board and a service line card. Themain control board is provided with multiple virtual service ports, which correspond to the physical service ports of the line card and share the same port index with the physical service port of theservice line card; the service line card receives a service message from a network end and sends the service message and the port index of the physical service port to the main control board; the maincontrol board receives the message through the virtual service port corresponding to the port index; the message is subjected to forwarding and query processing, so as to obtain the port index of thevirtual service port corresponding to a message target address; therefore, the service message is sent to the corresponding service line card; after the service line card receives the service message, the service message is sent through the corresponding physical service port. According to the system and the method in the invention, the logic complexity of a main control board software module andthe coupling of the software module of the main control board and the service line card are reduced, and the robustness of the whole system is improved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a system for cross-board processing of service messages and a redirection method 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 m...
