摘　　要：事件通知服务设计在面向服务环境下面临更多挑战,例如因特网规模下应用层接口、事件模型的互操作要求更高,事件通信实体与通知订阅的软状态管理等问题。目前,基于业务服务设计面向服务环境下的事件通知服务的工作还很少。本文从抽象的业务服务概念出发,设计并实现的事件通知服务具有事件派发模型独立于事件传输协议和编码、分布的事件通知代理体系结构以及按需派发事件等特点。该系统在项目中的应用表明了大规模动态多变的分布环境下本文设计的事件通知服务的正确性,以及由业务服务抽象带来的灵活性。The design of event notification under the service-oriented environment experiences more challenges like higher level application interfaces and event models, the soft state management of event entities and notification subscr/ption. Although the notification service is studied extensively, the counterpart based on business services is still often misunderstood, and no nore work has been done. This paper sets a viewpoint from business services, designs and implements a notification service with a transport-independent event delivery model, and an on-demand delivery event notification architecture. The implementation＇s successful application in large-scale dynamic distributed environments shows its correctness and flexibility in business services abstraction.
