基于GMP算法的安全计算机高速通信的容错设计*

Fault-tolerant design of safety computer high-speed communication based on GMP algorithm

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。

Abstract: 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 double 2 out of 2 structure, the results showed that the mechanism had obvious optimization effect on the fault tolerance of safety computer communication.
