一种动态多播组成员管理策略的研究

在研究了多播组成员管理协议以及当今多播路由协议的基础上，依据延迟休假队列模型
提出了一种新型动态组管理策略。在一个网络中，尽管在某一时间范围内一个特定的组成员数量为0 时，多播路由器不是简单地把该多播组从多播路由器中分离，而是采取一种智能的相关因子的方式决定多播路由器是否从特定的多播组中分离，从而可以减少在组成员维护时的代价。应用随机服务系统理论对该策略进行了建模并进行了理论分析。

Research on Dynamic Multicast Management Policy Mei Bing_Fu1, Li Yong_Jun 2 (1. Radio &Television Guangzhou University, Guangzhou, 510091 2. School of Computer Science & Engineering, South China University of Technology, Guangzhou, 510640) Abstract: Studying internet group management protocols and today’s multicast routing protocols, we propose a new strategy, which when the number of some multicast group is 0, the multicast router doesn’t simply separate the multicast group from itself and it adopts a intelligent factor which decide the multicast router to send prune information or not, if so, the multicast router will decrease the cost for managing the multicast group. In order to prove the strategy is efficient, Appling stochastic server system theory, we set up the model of the strategy and get a useful conclusion.
