Switch communication method and system and switch

Abstract

The invention provides a switch communication method and a system and a switch, wherein the method comprises the steps: at least two switch interfaces of a home terminal switch are pre-configured, the interfaces are connected with at least three opposite terminal switches, so that each switch comprises at least two communication links; a switch interconnection topology structure is acquired; an initial communication link between the home terminal switch and each opposite terminal switch according to the switch interconnection topology structure; when a target switch interface cannot communicate with the adjacently connected opposite switch, the interconnection topology structure of the switch is updated correspondingly; shortest communication links between the home terminal switch with each opposite switch is determined according to the updated interconnection topology structure of the switch, and each shortest communication link is started, so that the home terminal switch can communicate with each opposite switch through the corresponding shortest communication link. According to the technical scheme, the reliability of data transmission between switches can be improved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a communication method and system for an exchange, and an exchange. Background technique [0002] With the continuous development of cloud computing technology, the amount of data to be processed by the data center is also increasing, which requires more computing nodes to be configured in the data center. [0003] At present, in order to save hardware costs and space costs, data centers usually use full-rack servers. Each full-rack server integrates multiple computing nodes and multiple switches. Each switch is connected to a certain number of computing nodes in the full-rack server. Nodes, each switch is connected to each other, so that each computing node in the whole cabinet server can communicate with each other. [0004] However, in the above technical solution, there is usually only one communication link between every two switches in the server in the compl...

AI Technical Summary

Problems solved by technology

[0004] However, in the above technical solution, there is usually only one communication link between every two switches in the server in the complete cabinet. When the communication link is damaged, it may cause the corresponding two switches to fail to communicate normally. Data transmission between switches is less reliable
