Problems solved by technology

However, in practical applications, the implementation of the master-standby control logic is more complicated, and the master-standby functions are often prone to failures, and the faults related to the master-standby functions are difficult to locate and solve. The data and status of the host are not correctly synchronized, resulting in failure of the system to work normally or even business interruption after the switchover

Embodiment Construction

[0023] The method of the invention realizes the data consistency of the master and the backup by synchronizing the data between the master and the backup.

[0024] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] Such as figure 1 As shown, the steps of the master-standby data consistency detection method are as follows:

[0026] Step S101: Classify the data that needs to be consistent between the master and the backup.

[0027] Classify the data that needs to be consistent between the master and backup, and perform consistency checks for each type of data independently, which helps reduce the complexity of master and backup data consistency checks and provides more detailed master and backup data. The reason for the inconsistency of the backup data.

[0028] In this embodiment, data is divided into static data and dynamic data. Static data refers to configuration data, which must be saved...

Abstract

The invention discloses a method for detecting the consistency of main data and stand-by data, which includes the following steps: the data is classified; consistency detection of the main data and the stand-by data is started; main and stand-by synchronization of the data is paused; the consistency detection is operated by a main engine; the consistency detection is operated by a stand-by engine; and the synchronized operation of main and stand-by engines is recovered. The invention can detect the main engine and the stand-by engine dynamically and real-timely, and can alarm timely and automatically recover the consistency of the main data and the stand-by data when the main data and stand-by data is inconsistent. Besides, the invention can record the inconsistent alarm of the main data and the stand-by data, which is convenient to locate an inconsistent fault and shorten the time of locating the fault.

Description

technical field [0001] The invention relates to a communication technology, in particular to a method for detecting the consistency of master and backup data. Background technique [0002] In embedded communication equipment, in order to improve the reliability and security of the system, the main control board is often provided with the main and standby working mode. In the system of the main and standby working mode, under normal circumstances, one main control board is in a normal working state (called the master), while the other main control board is in the standby state (called the standby machine). When certain conditions are met, the main control board that was originally in the standby state will turn into the active state (this process becomes the active state). standby switchover) to ensure the normal and stable operation of the system. Before the active-standby switchover occurs, the standby machine should keep the same data and status as the main machine as muc...
