That is to say, only the information that the main party interacts with the outside world is out of order or lacking will be perceived by the outside world. Otherwise, how the main party handles it internally will not affect the outside world, but the delay may change.

Embodiment Construction

[0022] The core idea of ​​the present invention is: based on the aforementioned figure 1 It can be seen from the description of the current communication system that the active / standby switching mechanism is based on the delay requirement. Although this ensures the synchronization of switching data, the loss of message flow is unavoidable. In the present invention, by setting the backup mechanism of the main party, the message flow when the main party processes the message is backed up to the backup side. After receiving the new message, it is backed up to the backup side before processing and is set as a waiting state. After the master-standby switchover, The backup side can continue to process the message flow of the original master side, ensuring the lossless switching of the message flow. The object-based main-standby switching method of the present invention fully guarantees the reliability of the message flow of the communication system, and is simple and practical. The...

Abstract

The invention discloses an object-based master-standby switchover method, relates to the master-standby switchover technology in a communication system, and proposes to solve the loss of message flow in the current master-standby switchover mechanism. The technical solution adopted is: the master party receives the message Before processing, back up the message and the context of the message to the backup side, and notify the backup side to set the message as pending; after the message is processed, back up the data involved in processing the message to the backup side, and notify the backup side to set the message as processed Status; when switching to the main party, find out the messages whose status is pending, and process the pending messages first. The present invention provides complete message flow switching without causing communication data disorder and ensures the reliability of the communication system.

Description

technical field [0001] The invention relates to the master-standby switch technology in the communication system, in particular to an object-based master-standby switch method. Background technique [0002] In the communication system, in order to ensure the stability and reliability of the system, the active-standby redundancy mechanism is widely adopted. Normally, the primary side is in normal working state and the backup side is in standby state. When receiving the active-standby switchover command, the original standby side will become the active side, and the original active side will become the standby side. This conversion process is called active-standby switchover. During the switching process, data synchronization is the basis for ensuring smooth switching. How to ensure data synchronization is the core issue of the current active-standby switching mechanism. [0003] figure 1 It is a schematic diagram of switching timing in the existing active-standby switching...
