Master-slave control board real-time synchronization method and system

Abstract

The invention discloses a master-slave control board real-time synchronization method and a system thereof. The method comprises the following steps:a main control board processes the service, storesasynchronous data into a first-stage data buffer area of the main control board, stores data needing to be synchronized into a second-stage data buffer area shared with a standby control board, and communicates with the standby control board through timing heartbeat, and the standby control board only communicates with the main control board; and the standby control board is switched into a main working state through main and standby judgment, so that the second-stage data buffer area can be read and written, and the original main control board does not read and write the second-stage data buffer area any more. Compared with the prior art, the method at least has the following beneficial effects that the main and standby synchronization process is remodeled, time-consuming batch synchronization is effectively avoided, real-time backup operation with high system overhead is replaced, the smoothing process is simplified, smooth transition of service processing in the main switching process is ensured, and the stability and reliability of the system are improved.

Description

technical field [0001] The invention relates to a communication system, in particular to a real-time synchronization method and system for active and standby control boards. Background technique [0002] In order to improve the reliability of the communication system, the application of the 1+1 active and standby control board mechanism is becoming more and more common. When the main control board is dual-configured, the main control board works normally, and the standby control board is in the backup state. The consistency of data is ensured through high-reliability mechanisms such as batch backup and real-time backup between the active control board and the standby control board. When the backup control board receives the information that the main control board is working abnormally or the master-standby switchover command, it will quickly take over the work of the main board. [0003] In the traditional method, the synchronization process of the active and standby contr...

Problems solved by technology

[0003]In the traditional method, the synchronization process of the main and standby control boards is mainly divided into three stages: batch backup, real-time backup and data smoothing. For systems that require frequent changes in backup data, such as application In the telecommunication network system, the business information backed up in real time is large and changes frequently, which increases the system overhead and also increases the time for data smoothing

And the smooth process needs to wait for the data and status maintained by the system to be consistent before the standby device can really become the active device. Therefore, in a system that is sensitive to delay, it cannot meet the requirements of real-time processing
