Double computers online backup system based on messagesynchronize on the mobile services switchingcentre’s application

本文分析了当前双机热备份系统设计中存在的问题,提出了一种基于消息同步的双机热备份系统的实现方法,并将之应用于移动业务交换中心的设计中。该方法可以实现容错对上层业务的透明性和容错结构的动态性。

This paper analyse the problems in the design of double computers online backupsystem. With consideration of these problems, a method of implementing a double computers onlinebackup system based on message synchronize is proposed. And we apply this method to the systemdesign of mobile services switching centre. The method can make the function of fault tolerancebeing transparent to the service of high level.
