摘　　要：容错是提高WebServices可靠性和可用性的关键技术。本文提出了在WebServices中实现容错的三种方案:基于后台服务对象的容错、基于Web服务器的容错和基于Web服务的容错,并分析、比较了这三种方案的优缺点。在基于Web服务的容错方案的基础上,提出了一个通用的WebServices容错管理框架-WSFMF,并分析了其实现关键,给出了相应的解决方案;最后在我们自主开发的WebServices平台—StarWS上进行了相应实现。Fault-tolerance is the key technology to improve the reliability and availability of Web Services. This paper puts forward three fauh-tolerant approaches to Web Services, which are the fault-tolerance based on backend objects, the fault-tolerance based on Web ervers and the fault-tolerance based on Web Services. The merits and demerits of each approach are also discussed. With the method of fault-tolerance based on Web Services, we propose WSFMS, a Web Services fault-tolerant management framework. The key technologies in realizing WSFMF and our solutions to each technology are also discussed. And we realize the framework on the Web Services platform called StarWS developed by ourselves.
