A data compatibility method, inter-board message compatibility method and corresponding system

Abstract

Disclosed are a data compatible method, an inter-board message compatible method and corresponding systems. The data compatible method is applied after a standby control board downloads a new software version in a process of software upgrade using an active / standby switchover mechanism. The method comprises: an active control board and the standby control board respectively extracting structure information of various structures in a local database, the structure information at least comprising length information of the corresponding structures; the active control board sending the structure information of the local various structures to the standby control board; the standby control board comparing received information of each structure with the structure information of the corresponding local structure; and if the received information of a structure is inconsistent with the structure information of the corresponding local structure, extending the data, which is synchronized to be local by the active control board and belongs to the structure, to the data of the local corresponding structure, and then storing the data at a corresponding position of the structure in the local database.

Description

technical field [0001] The invention relates to the communication field, in particular to a data compatibility method, a message compatibility method between boards and a corresponding system. Background technique [0002] Usually, when a new requirement is added to the equipment or a major failure is resolved, a software version upgrade is required. The normal way to upgrade is to reboot the device and re-download the new version of the software. Using this method will result in service interruption during the period of device restart. Therefore, it is necessary to use an upgrade method without service interruption in many occasions. [0003] The existing non-interrupted service upgrade method is to use the hot backup mechanism to copy the new version software to the standby control board, and simulate the main-standby switchover mode to realize the non-interrupted service upgrade. like figure 1 As shown, the specific process is as follows: restart the standby control b...

AI Technical Summary

Problems solved by technology

[0006] 1. There are often thousands of inter-board data structures in communication equipment. When it is necessary to expand the message, it is impossible to modify the sending and receiving processing of each module one by one;

[0007] 2. When module A contains the structure of module B, if the structure of module B is expanded, it will affect module A

[0008] Therefore, for many devices that are upgraded without interrupting the service, the new version of the device is greatly restricted in terms of data structure expansion, and in many cases, only a strategy of no expansion or minimal expansion can be adopted.
