A method, system and device for realizing master/slave switching

Abstract

The embodiment of the invention discloses a method for achieving an active / standby switching. The method includes that: when carrying out the active / standby switching, a system sends received data to a standby device corresponding to a physical IP address which has a mapping relationship with a communications identification prearranged. The embodiment of the invention also discloses a system and a device, which achieve the active / standby switching. By applying the method, the system and the device of the embodiment of the invention, an ongoing service can be prevented from longtime interruption when the active / standby switching is carried out.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a method, system and equipment for realizing active-standby switching in a communication system. Background technique [0002] At present, the requirements for the reliability of the communication system are getting higher and higher. In order to ensure the reliability of the communication system in the existing technology, the master-standby switching technology is often used, that is, two devices are set up as the master and the backup. The active equipment provides services for the system; when the active equipment fails, it switches to the standby equipment, and the standby equipment provides services for the system. The master and backup devices mentioned here are only relative concepts. In practical applications, the two devices are usually mutual backups. [0003] The active and standby devices share the same floating IP externally. The floating IP mentioned here refers ...

Problems solved by technology

As shown in Figure 1, under normal circumstances, the main device A occupies the floating IP, and the data sent by the application device (APP) to the floating IP will be sent to the main device A; And the process shown in Figure 3, that is, as shown in Figure 2, release the occupation of the floating IP by the active device A. At this time, the system is offline and cannot work normally; as shown in Figure 3, the active device A successfully completes the release After the operation, the standby device B occupies the floating IP

[0005] Although the above method can realize active-standby switchover, the physical environment setting needs to be modified during the process of releasing the floating IP of the active device and occupying the IP by the standby device, which will cause the interruption of the current business; and modifying the physical environment setting The process usually takes a long time
