摘　　要：针对目前分布对象中间件消息通信机制中不支持时间解耦和服务质量控制的问题,提出一种能够支持消息异步传递和时间解耦的异步通信模型,通过在客户端引入消息转换层来完成异步消息的提取、包装和转换,将原始的请求转换为一种可路由的消息,然后设计一种软件路由代理来实现异步消息的传递与转发。文章重点论述了分布对象中间件异步通信软件路由代理的工作机制、体系结构,提出了创建持久请求算法及软件路由代理的请求处理算法。To solve the problem that the current messaging communication mechanism of distributed object-oriented middleware doesnt support time decoupling and control of quality of service, we present a new asynchronous communication model which can support asynchronous messaging and time decoupling. Through adopting message conversion layer in client, it can pick-up, package and convert the asynchronous message, converting initial request to message that can be routed. And then we design a software route agent to achieve transmission and retransmission of asynchronous message. This paper highlights on the work mechanism, architecture, and presents algorithm of create persistent request and request processing algorithm of software route agent.
