摘要
相异性设计是为避免共性故障而采取的一种设计方法 ,是不同的工作组根据一个初始规范分别设计满足规范的独立工作系统 ,通过互相之间的故障监控 ,对发生的故障进行检测、隔离和定位 ,并可能进行重构 .这种系统容错概念的理论基础是独立开发系统 ,不会发生共性故障 .为此介绍了相异性设计的概念及几个使用相异性设计实现的容错系统 。
Diversity design is used to aviod the generic failure and it require independent development of multple version of software or hardware according to an initial specification. Each version works or runs independantly. This system can detect?isolate and locate the failure through comparison monitoring. The theory behind this method is the failure will inpendantly(not generic) happen using indanpantly developed versions. Some typical system developed by using diversity principle are described and some of the systems are further analysed as well.
