基于CORBA的分布式信息处理异步消息通信研究

Research of Asynchronous Message Communication in the Distributed Information System Based on CORBA

分布式计算是目前计算机应用领域中研究的热门课题,而在分布式系统中,对象之间的通信是一个关键技术.研究了基于公共对象请求代理结构(common object request broker architecture, CORBA)的分布式信息处理中的异步消息通信问题;讨论了如何实现CORBA的事件服务;提出了通过建立事件信道、事件发送者与接收者模型的方法,来实现异构网络环境下的非耦合异步消息通信.使用这种方法,提高了所开发的分布式信息处理系统的信息接发与处理的速度,解决了系统的通信阻塞等问题;同时该方法在系统中的成功使用,为提高分布式信息处理系统的机间通信速度提供了解决方案.

Distributed computing is one of the most important method in computer application field. Communication between the objects is the key in the distributed system. The paper studies the details of asynchronous message communication based on CORBA in the distributed information system. The paper discusses how to realize the event service. We realized it through building event tunnel, event push model and event pull model. The system promoted the speed of incepting and dealing with information, and solved communication in the distributed networks. The method is successfully applied to the system, and the resolvent raising communication rate of distributed information system is provided.
