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

Abstract

The embodiment of the invention provides a method and device for forwarding messages, a switch, a piece of equipment and a storage medium. The method includes the following steps: acquiring a messageto be forwarded; querying whether a first data table contains the connection cache information of the message to be forwarded; acquiring first identification of the connection cache information in thefirst data table if the first data table contains the connection cache information of the message to be forwarded; acquiring connection information corresponding to the connection cache information in a second data table, and determining second identification of the connection cache information, wherein the second identification is the current connection identification of the connection cache information, and when the connection information of the connection cache information changes, the current connection identification of the connection cache information whose connection information changes correspondingly changes according to a preset change rule; and if the first identification and the second identification of the connection cache information are the same, forwarding the message to be forwarded according to the connection cache information. The method for forwarding messages provided by the embodiment of the 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
