摘要
在关键任务部门中 ,实时双系统的应用越来越广泛。如何保证高的可用度和高的响应时间是它们共同面临的问题。在本文中 ,全面论述了强实时双系统容错技术中的关键问题 ,包括系统结构定义、故障检测、状态切换。实际应用的结果表明 ,方案可以满足应用系统高可靠、强实时的需求 。
The hard real time dual systems are applied in crucial tasks widely. The common problem they face is how to guarantee the high availability and the high response time. A full discussion of the key problems in hard real time dual system is presented, including the definition of system architecture, fault detection and state transition. The practice shows that the solution can meet the requirement of high availability and hard real time, and the achievement is outstanding.
