摘　　要：在分布式中间件系统中,分布式对象间需要频繁的进行信息交互,如何高效并且可靠的传输消息成为分布式中间件系统研究的关键之一;针对这些需求,提出了基于TAO的实时事件服务,利用订阅/发布机制搭建分布式中间件系统平台,建立适用于状态分布式对象订阅/发布的支撑环境;详细介绍了中间件系统中状态分布式对象的订阅/发布流程;最后针对该中间件系统平台进行了性能测试,在千兆以太网环境下,中间件系统传输时延随着事件大小的增加而增加,而且传输时延在网络传输中基本符合要求。In the distributed middleware system, Distributed objects which carry the special information need to communicate frequently with each other, How to translate information effectively and reliably has become one of crucial parts of distributed middleware system re- search. Against these requirements, we raise a theory which based on the Real-Time Event Service of TAO, using the publish/subscribe mechanism sets up the distributed middleware system platform, builds the back up environment which is adequate for the subscription/pub- lication of Stateful Distrlhute Object. We also introduce the Publlsh/Subscribe processing of middleware system in detail. In the end, the property test for the middleware system platform was given. Under the Gigabit Ethernet environment, the transmission delay of the middle- ware system is increased with increasing event size, meanwhile, the transmission delay basically meets the requirement in network transmis- sion.
