摘　　要：安全计算机普遍采用分布式冗余结构但未有相应的容错管理机制,文章采用基于时间触发机制的通信方式,提出基于GMP(Group Membership Protocol)算法的高速通信容错机制。在2乘2取2结构的安全计算机平台上对容错机制进行了验证,结果表明,该机制对安全计算机通信的容错性有明显的优化效果。As the distributed redundant structure is widely used in safety computers without corresponding fault-tolerant management mechanism,this paper used the time triggering mechanism based communication mode,and put forward GMP(Group Membership Protocol)algorithm based high-speed communication fault tolerance mechanism.Then the fault-tolerant mechanism was verified through the safety computer platform with double2out of2structure,the results showed that the mechanism had obvious optimization effect on the fault tolerance of safety computer communication.
