Abstract The fast-developing e-business of enterprises has changed the scales of distributed
systems,where making the point0to-point and synchronous communication based on request/reply paradigm is not enough for the large-sacles dynamically distributed application environment. The SOA-based publish/subscribe system model supports many-to-many communication and time,space,and control flow of subscribers and publishers and provides the loose coupled form of interaction required in the lage-scale system. In order to cooperate among the entities in a large-scale distributed system,the paper presents and practices a design model of SOA-based publish/subscribe system.
