【摘要】 简单对象访问协议SOAP是新一代分布式计算模型Web服务的基础,然而SOAP应用的性能问题是制约其发展的主要方面。该文从SOAP消息处理与SOAP消息传输两个方面,就影响SOAP应用性能的因素进行了分析,并论述了可以改进其性能的技术方法。在此基础上,该文采用Agent技术,提出了一个基于Agent的SOAP应用框架,并在面向Web服务的服务协作中间件中实现了此框架。该文的SOAP应用框架解决了SOAP应用的性能瓶颈问题,同时具有灵活的扩展机制,为基于Web的分布式计算提供了可行的实现模式。更多还原

【Abstract】 Simple Object Access Protocol is the foundation of Web Service,which i s the next generation distributed computing.However,the low performance of SOAP applications is one of the main obstacles for acceptance of SOAP.In this paper ,we have analysed the issues related to performance of SOAP applications in tw o sides,processing SOAP message and transporting SOAP message.Furthermore,by introducing agent technology,we present an agent-based SOAP application fr amework,and implement this framework in Service Cooperation Middleware.Our f ramework has resolved the performance bottleneck in SOAP applications,and it al so has a flexible extensibility.So it will produce an executive pattern for web based distributed computing.更多还原
