| 摘 要： | 针对网络故障以及Web服务节点暂时性失效,导致Web服务请求出错的问题,提出了一种Web服务容错机制.通过建立服务补偿机制和Web服务会话管理机制达到容错的目的.首先对Web服务的容错性问题进行了分析;接着详细论述了服务补偿机制和容错框架的设计与实现方案;最后通过在政务服务集成系统中的应用实例说明了该容错机制能够有效地增强Web服务请求调用的可靠性.

| Abstract: | Aiming at the problem that web service calling goes away due to the influence of the faults of network and temporary lapse in web service nodes,a web services fault-tolerant mechanism is proposed.The fault-tolerant is realized by the establishment of the mechanisms of web service compensation and web service session management.First,it analyzes the web services' fault-tolerance problems;then it elaborates the design and implementation approaches for compensation mechanism and fault-tolerant framework.Finall... |
