提高CORBA应用系统响应的混合优先多线程机制

Using Mixture and Priority Policy of Multi-thread to Improve the Responsibility of the CORBA Application System

1 问题的提出 近年随着网络技术的发展,以及在OMG组织提出COR-BA标准后,分布式系统已经由原来的以客户机/服务器方式为主的结构,发展为多采用CORBA做为中间件的客户机/中间件/服务器三层结构,而且已经成为当前信息集成框架的主流技术,如在制造业、通讯、金融和财政等领域纷纷提出相应的集成框架,并利用CORBA提供的公共服务.

The distributed system architecture has changed from client/sever to based-CORBA client/middle-ware/ server. How to improve the responsibility of this system in order to solve the server bottleneck? The efficient method is multi-thread. Analyzing the thread policies that are already used in CORBA application systems, a new policy-MIX and PRIORITY is proposed in the paper to improve the responsibility and throughput. And the implement issue is researched at last.
