高可用冗余切换CompactPCI平台在网络通信上的应用

Application of a Redundant System Slot CompactPCI HA Platform on Network Communication

为了获得高可靠和高带宽的通讯平台,设计了CompactPCI高可靠平台。该平台可以对包括主系统板的所有插件提供冗余备份,实现故障自动隔离,备件自动连接,可在不停机的情况下拔插系统板及其它插件。介绍了基于VxWorks实时操作系统下应用CPCI双机热备系统实现网口的高可用性的网络通信。

In order to get high availability （HA） and high bandwidth communication platform,A redundant system slot CompactPCI HA platform is designed.This platform supports redundancy and hotswap for all boards including the main CPU board.This paper introduces the network communication in the dual module hot spare computer under the RealTime Operating System VxWorks.
