| 摘 要： | HTTP协议提供尽力传送服务无法满足Web Service对可靠SOAP消息传递的需求。针对WS-Reliability规范,设计开发了基于中介体的可靠Web Service消息传递系统。Web Service通信双方通过一组对等中介体发送和接收HTTP报文,由中介体实现报文的有保证传递、重复消除和传递排序,并提供日志管理和用户自定义可靠级别功能。实验结果表明,基于中介体的可靠Web Service消息传递系统完全符合WS-Reliability规范,且易于部署,保持了传统Web Service中必不可少的简单性和互操作性,为Web Service应用构建了可靠支撑平台。

| Abstract: | Reliable messaging is critical for Web Services,but the best effort delivery service provided by HTTP protocol can not ensure reliable messaging.According to WS-Reliability standard,this paper proposes a reliable messaging system based on intermediary.In the system,two peer intermediaries lie between the client and server,which ensure guaranteed delivery,ordered delivery and exactly-once delivery of HTTP packets.Experiment result shows,the reliable messaging system based on intermediary satisfies the requirement of WS-Reliability standard and is easy for deployment,and provides a founded platform of Web Service applications. |
