一种基于面向服务计算平台的事件处理模型

SOA implementations based on request/reply model lack certain loose coupling and cooperativity. Event-Driven Architecture (EDA) is particularly suitable for loosely coupled communications. By introducing Event-Driven paradigm into Service-Oriented Architecture, the system can achieve loose couple communication and cooperativity. But the traditional event-handling model can not cope with highly complex and dynamic real-time business issues and can not provide flexible publish and subscribe. This paper presents an improved event-handling model, which introduces event filter to filter the events in order to get the service according to the consumer's interest. The model will be used widely due to its flexible response to users' request through customizable rules generated by rule controller. The algorithm used in rule controller is not concerned about in this paper.
