摘　　要：随着OSP(FOpen Shortest Path First,开放式最短路径优先)协议的不断发展与应用,其稳定性在网络应用中的重要性显得越发明显。文章基于OSPF协议,提出在多主控系统中引入OSPF同步机制,对其可靠性进行了分析研究。该方法通过检测设备事件处理机制,分别执行初始化同步与实时同步流程。同步包括实例、接口、邻居、链路状态通告在内的所有OSPF信息,从而保证主控系统间OSPF信息保持同步。通过引入OSPF同步机制,在实际应用过程中交换机路由业务的可靠性得到很大提升。With the development of OSPF（Open Shortest Path First） protocol,its stability is becoming increasingly important in network applications.This paper proposes OSPF synchronization mechanism in multiple master systems and analyzes the reliability based on OSPF protocol,which can be divided into initialization synchronization and real-time synchronization through event processing mechanism detection. The synchronization message contains all the OSPF information including instances,interfaces,neighbors, link-state advertisements,which makes different master systems synchronized.The results prove that the reliability of routing services in practical applications is dramatically improved by introducing OSPF synchronization mechanism.
