| 摘 要： | 在分布式环境下,许多分布式实时应用都需要一个可扩展的事件驱动通信模型来使得事件提供者和消费者实现异步通信,同时能够增强目前的分布式应用的QoS特性,CORBA事件服务体现了事件提供者与消费者的灵活异步通信机制,本文在探讨CORBA事件服务及其不足的基础上,讨论了扩展CORBA事件服务实时特性的总体框架及实时性能设计,并实现了一个基于CORBA的分布式实时事件服务,最后,测试结果验证了该服务能够满足一定的实时需求.

| Abstract: | Many distribute real-time applications require a scalable event-driven communication model thatprovides the asynchro- nism between suppliers and consumers. At the same time, it can enhance advanced quality of service (QoS). The CORBA event service provides a flexible model for asynchronous communication in distributed objects. The CORBA event service and its draw- back is discussed in this paper, then the frame and the attribute of event service is extended. The next, a distributed real-time event service is implemented. The result of experiments show that the service is able to satisfy some real-time requirements. |
