摘要
针对分布对象中间件异步通信中时间、空间和流程的三刻度解耦问题进行了研究,在分析了当前分布对象中间件通信机制所存在的问题基础上,基于CORBA分布环境引入了P/S发布订阅系统,构建了基于P/S模式的CORBA通信体系。同时在P/S中间件代理体系中,引入移动Agent代理技术构建了基于Agent与P/S混合模式的异步通信算法,解决了基于中间代理的分布对象中间件异步通信的三刻度解耦问题。
The three problems of time, space and flow coupling in asynchronous communication is researched and based on analyzing current problems of communication in distributed object-oriented middleware, publish/subscribe scheme in CORBA distributed environ- ment is adopted and CORBA communication based on P/S scheme is established. In P/S mediator system, adopting moving agent technique, the asynchronous communication arithmetic based on mix model of agent and P/S scheme is built. For solving the coupling problems in asynchronous communication based on middle proxy in distributed object-oriented middleware.
