Abstract:

The design of event notification under the service-oriented environment experiences more challenges like higher level application interfaces and eventmodels, the soft state management of event entities and notification subscr/ption. Although the notification service is studied extensively, the counte  rpart 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.

Key words: service-oriented computing, business service, event notification, service bus, on-demand delivery
