IP组播路由技术研究

Research on Ip Multicast Routing Technology

IP组播通讯是一种比传统的点对点更有效的技术。它能通过一点对多点或多点对多点发送信息,可以用很少的服务流给大量的用户提供服务,即使用户数量成倍增长,主干带宽也不需随之增加。这个优点使其成为当前网络技术的研究热点之一。对几种IP组播路由协议进行了研究与分析,指出了存在的问题,讨论了IP组播未来的研究方向。

IP Multicast communication is a kind of more efficient mechanism than traditional point-to-point transmission, it can send data form one or multiple sources to multiple receivers, and it can provide services to many users with few service flow. Even if the number of users increase several times, the backbone bandwidth don＇t need to be raised. So IP Multicast has been one of the hottest topic among current networking technology reaching field. Some IP multicast routing protocols were researched and analyzed, and the existing problems were pointed out. In the end, the direction of IP multicast in the future were discussed.
