Abstract
The present invention relates to a method for realizing the hot backup of a master control board, which belongs to the technical field of data communication. In the method, modules for the communication between boards are respectively arranged on the master control board and a service board, and the addresses of interfaces for the communication between the boards are respectively registered for the master control board and the service board; a hot backup module, a hot backup registry and a hot backup interface address are set on the master board and the backup board of the master control board so as to establish a data backup interface. When the backup is started, both the master board and the backup board are in a hot backup state, and then mass data backup and real-time data backup or timing data backup are orderly completed between the master board and the backup board; when the original master board breaks down, the backup board becomes a new master board, and data is exchanged between the new master board and the service board. The method of the present invention realizes the data backup of the master board and the backup board during normal operation and the data exchange between the new master board and the service board after the breakdown of the master board, and ensures that the backup board becomes the new master control board without affecting the operation of the service board.
