本文综合评述了基于内容的P/S系统路由机制和算法.根据客户的移动性和网络结构的变化对路由算法进行了分类和归纳,分别论述了静态和变化拓扑环境下、支持客户移动情况下P/S系统各种路由算法的基本思想和优缺点等.在此基础上,针对P/S系统的动态、松耦合,多对多通信的特征,分析和提出了有待解决的问题以及进一步的研究方向.
This paper discussed and reviewed various routing mechanisms and algorithms of the content-based publish-subscribe systems. By the client mobility and dynamically changed network topology the routing algorithms were classified, with their basic ideas, merits and shortages described in details respectively. According to the characters of dynamics, loose coupling, and many-many communication in the publish-subscribe systems, some unsolved problems were introduced and analyzed for the future research.
