Method, device, switch, equipment and storage medium for forwarding message

Abstract

Embodiments of the present invention provide a method, device, switch, device, and storage medium for forwarding a message. The method includes: obtaining a message to be forwarded; querying whether the first data table contains connection cache information of the message to be forwarded; A data table includes the connection cache information of the message to be forwarded, and obtains the first identifier of the connection cache information in the first data table; obtains the connection information corresponding to the connection cache information in the second data table, and determines the second identifier of the connection cache information. An identifier, wherein the second identifier is the current connection identifier of the connection cache information, and when the connection information of the connection cache information changes, the current connection identifier of the connection cache information whose connection information changes is changed accordingly according to the preset change rule; if The first identifier of the connection cache information is the same as the second identifier, and the message to be forwarded is forwarded according to the connection cache information. The message forwarding method in the embodiment of the present invention can reduce message forwarding errors.

Description

technical field [0001] The invention relates to the technical field of digital information transmission, in particular to a method, device, switch, equipment and storage medium for forwarding messages. Background technique [0002] A vSwitch (Virtual Switch, virtual switch) is a virtual device running on a computing node host computer in a public cloud environment, and is used to realize the functions of a physical switch in a layer 2 and layer 3 network through software. The vSwitch is mainly responsible for packet forwarding based on MAC (Media Access Control) addresses at Layer 2 and IP addresses (Internet Protocol Address, Internet Protocol Address) at Layer 3. It also has functions such as security groups and ACL (Access Control List, Access Control List). [0003] In the existing technology, when using a virtual switch to forward a message, when the message sending end and the message receiving end are in the same subnet, it is necessary to query the Layer 2 MAC addres...

AI Technical Summary

Problems solved by technology

[0004] However, in the existing technology of using virtual switches to forward packets, when the connection state of the device corresponding to the connection information changes or the configuration of the control plane changes, the connection information will become invalid, and forwarding packets according to the expired connection information will cause the packet Send Error
