Processing method for node link switching of the distributed system and its device

Abstract

The present invention provides a system of distributed processing nodes link switching method and device applied to a two-port node in the distribution of the different business Ring Network board, including the link state records module and link processing module, the board installed at the business, the link state records module records each port ring network link state; Chains processing module change in the link state, which under the current business plate by Ring Network link state, compared with the record of the plate business link state ring network is consistent, if not the same treatment, if not then switch to link processing, and / or through plate Channel Communication between nodes notice with another port of the current business Plate Ring Network link state, another port link processing module of the business after the board received relatively current with its ring network link state records ring network link state, if they are not consistent treatment, if not then switch to link processing.

Description

technical field [0001] The invention relates to the technical field of inter-board communication of high-end routing distributed switches, in particular to a method and device for processing node link switching in a distributed system. Background technique [0002] The distributed system consists of a main control board and multiple service boards. The main control board is mainly used to control the entire system and coordinate each board. The business board is mainly used to transmit data. Each board has a central processing unit. Various information exchanges are required between the boards. When the control messages of the Ethernet ring network automatic protection system are exchanged between boards, there are high requirements on the real-time and reliability of the control message processing. When multiple ports of the Ethernet ring network nodes are distributed on different service boards, multiple service boards need to coordinate the processing of the same task ev...

AI Technical Summary

Problems solved by technology

When the two service board central processors of a switch node process the same event task in parallel, the processing sequence is prone to errors, or processing delays due to mutual waiting for messages, resulting in link switching errors in the Ethernet ring network protection system, protecting business The data of the VLAN generates a loop or disconnection, and the network fails.
