面向电子政务的发布订阅中间件设计与实现

Design and Implementation of Publish/Subscribe Middleware for E-government

目前紧耦合通信模式已经不能满足大规模电子政务应用发展的需求,迫切需要一种新的松耦合信息交互基础设施,而发布订阅中间件是解决该问题的有效技术。基于客户/网络体系结构,提出一种发布订阅中间件系统Xinfo,设计其总体框架和关键组成部分,给出面向代理网络的消息路由算法。实际部署测试结果表明,Xinfo系统能够解决大规模电子政务系统间的松耦合信息交互问题。

At present the tightly coupled communication paradigm can no longer meet the needs of development of large scale E-government applications. And it needs a loosely coupled information interchanging infrastructure to support development of E-government applications. Publish/Subscribe middleware is an effective technology to settle this problem. Based on the client/network architecture, the Publish/Subscribe middleware system Xinfo is presented. Its main framework is put up with key component. A message routing algorithm for broker network is also presented. The result of testing Xinfo system in real application scenario shows that it is the effective technology to settle the problem which is loosely coupled communication among large scale E-government applications.
