Problems solved by technology

[0003] In response to this problem, the existing technology speeds up the confirmation of the status of each server by shortening the cycle of sending health detection messages by the first load balancing device. However, this solution can only shorten the service interruption time to a limited extent, and cannot completely eliminate the master-standby switchover situation. possible business interruption

Abstract

The invention provides a master-slave switching method and device. In the application, after master-slave switching is carried out, first load balancing equipment can distribute the received service flow according to various server states sent to the local by second load balancing equipment at first; and, after the local obtains the server states through an active detection mechanism, the received service flow is distributed according to actively detected server states, so that the possible service interruption phenomenon under a master-slave switching condition can be eliminated.

Description

technical field [0001] The present application relates to the technical field of network communication, and in particular to a master / standby switching method and device. Background technique [0002] In order to improve network reliability, silent dual-system hot backup technology has become one of the commonly used technical means in networking technology. in such as figure 1 In the networking environment shown, the load balancing device adopts the silent dual-system hot backup technology. Specifically, the networking environment involves a dual-machine hot standby system, which includes the first load balancing device that is the backup device before the master-standby switch, the master device after the master-standby switch, and the master load balance device before the master-standby switch. device, and the second load balancing device that is the backup device after the active / standby switchover. Among them, before the master-standby switchover, the second load bal...
