摘　　要：基于内容的发布订阅系统多数采用泛洪和匹配优先的路由算法。本文提出了基于事件空间划分的发布订阅系统的实现方法,采用组播的方式实现了目标代理到多个订阅者之间的通知路由算法。与采用贪婪路由思想的单播路由算法相比较,该算法提高了在通知路由阶段的发布订阅系统的路由效率。算法对解决基于内容的发布订阅系统中相关的路由问题具有重要的作用和意义。最后给出了算法的仿真实验。Many content-based publish/subscribe systems use broadcast and match first routing algorithm. This paper puts forward an implementation based on event space division publish/subscribe system. Compared with the unicast algorithm using greed routing thinking, this algorithm improves the routing efficiency of the publish/subscribe system in the notification muting period. This algoritlnn is of important meaning to solve the routing problem in content-based publish/subscribe system. At last the paper gives out the emulation,
