中文摘要: 阐述了为紧要使命(critical mission )所用的分布式系统中,为解决应用中可信度问题,需要将实时与容错作为一个整体问题来加以研究。利用实时容错中间件的思想,创新性地解答新一代需求中分布式系统的实时—容错问题;在分析了实时与容错融合的困难基础上,提出了实时容错中间件的思想,研究了实时容错中间件的体系结构,给出了一种基于服务方式的三层实时-容错中间件模型,并讨论了其具体设计细节,包括其中的服务器和中间层组件、接纳测试、任务分配算法和调度服务,为处理紧要任务的分布式系统提供了平台系统。

Abstract:The fusion of real-time and fault tolerant is needed to solve the problem of dependability for the critical mission distributed system, and the real-time fault tolerant middleware was proposed. The difficult for the fusion of real-time and fault tolerant was analyzed,the idea and architecture of the real-time fault tolerant CORBA middleware was put forward, and then the service oriented, three-layer, and real-time fault tolerant middleware model, and it’s detailed design were presented, including the design of the component of the middle layer and the sever layer, admission test, task assignment algorithm and scheduling service, which provides a platform to deal with critical mission in distributed system.
