摘要： CORBA交易服务是CORBA系统中获得远程对象引用的关键,交易者之间相互连接形成联邦。但CORBA交易者联邦是静态手工建立的,不能适应动态网络拓扑结构的变化。该文扩展了交易服务,从而对交易者联邦进行动态管理,并使用最小生成树对交易者联邦间的连接进行了优化。

Abstract: In distributed systems,tools for discovering objects that provide a given service,and for choosing one out of many are essential. The CORBA trading service is one of these tools. A trader federation extends the limit of a discovery, thanks to the cooperation of several trading servers. However, in a federation, cooperation links are manually and statically established. They may not adapt the change of underlying network topology. In this paper, it proposes an extended trading service, which manages a trader federation dynamically. With extended trading service, optimized links between traders are automatically set up thanks to the use of minimum-weight spanning tree.
