Problems solved by technology

[0002] Each server in the existing redundant backup system is based on the vrrp protocol (Virtual Router Redundancy Protocol, Virtual Router Redundancy Protocol) to achieve server high availability solutions, thereby avoiding single point failures, such as once the main server fails or goes down , the standby server needs to be switched to the main service state to take over the virtual IP (Internet Protocol, Internet Protocol) and continue to provide services to the client, but the existing server state detection and switching process is too long, resulting in the inability to meet some higher time precision requirements. Service or business switching requirements

Embodiment Construction

[0042] Such as figure 1 As shown, it is a schematic diagram of a data interaction scene between a redundant backup system and a client (Client) in the prior art. The redundant backup system may include a master server (Master) and a backup server (Backup), and the master server A keepalived application implemented based on the vrrp protocol runs in the backup server and the backup server, so as to avoid a single point of failure.

[0043] exist figure 1 In the data interaction scenario shown in , for the client, the virtual IP (VIP, VirtualIP) address can be used to log in to the redundant backup system for service access or business use, and as long as one server in the redundant backup system can work normally Operation can ensure the normal operation of the corresponding service or business. For the redundant backup system, the redundant backup system appears as a VIP to the outside, that is, during the actual operation of the redundant backup system, the main server in t...

Abstract

The embodiment of the invention provides a state switching method and device. The state switching method comprises the steps of receiving a multicast message sent by each second server; for each multicast message, extracting the priority of a second server sending the multicast message from the multicast message; and comparing the own priority with the extracted priorities in the multicast messages, and performing state switching when a comparison result satisfies a state switching condition. Based on the multicast synchronization mode, the state switching of the server is realized, and the state switching time can be effectively shortened.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular, to a state switching method and device. Background technique [0002] Each server in the existing redundant backup system is based on the vrrp protocol (Virtual Router Redundancy Protocol, Virtual Router Redundancy Protocol) to achieve server high availability solutions, thereby avoiding single point failures, such as once the main server fails or goes down , the standby server needs to be switched to the main service state to take over the virtual IP (Internet Protocol, Internet Protocol) and continue to provide services to the client, but the existing server state detection and switching process is too long, resulting in the inability to meet some higher time precision requirements. Service or business switching requirements. Contents of the invention [0003] In view of this, the purpose of the embodiments of the present invention is to provide a method and...
