摘　　要：主备倒换技术是保障机架式通信设备的可运维性关键技术之一。提出一种新的高可靠性通信设备主备倒换软件实现方式,并对其关键技术——高可靠性协议进行了深入研究。区别于传统的主备倒换流程,系统在倒换之前,主备控制卡之间进行实时的数据同步,从而将数据同步从倒换的过程中分离开来。经实验验证,该方法既能保证主备倒换数据的准确性,又能缩短主备倒换的时间,实现无缝倒换,且适用于机架式通信设备。Main/Standby switch technology is one of the key technologies which can safeguard operation and maintenance of communication equipment. A new high reliability implementation of main/standby switch software is referred to in this paper, and its key technology high availability protocol is deeply researched. It is different from traditional main/standby switch process. Before the system switch, it has finished real-time data synchronizes between the active and standby control card. Thus data synchronization is isolated from changeover process. Verified by experiment, this method is not only to ensure the accuracy of the main /standby switch data, but also reducing main/standby switch time and realizing the seamless switch, and suitable for communication equipment.
