摘　　要：Web Service的分布、异构和动态特性使面向服务的软件系统易受网络和软硬件故障影响,导致Web Service不可用,进而使整个SOA系统失效。论文提出一种基于服务冗余的容错体系结构,给出服务域划分规则,并介绍了三种容错策略以及一般的容错过程。Due to distributed, heterogeneous and dynamic characteristics of web services, service-oriented software sys- tems is prone to be susceptible to network, hardware or software failures, leading to unavailable of web services, then cau sing the entire SOA system failure. This paper presents a service redundant-based fault-tolerant architecture, service domain division rules, and introduces three fault-tolerant strategies as well as the generic tolerant process.

关 键 词：面向服务的体系结构 服务冗余 容错
