多媒体通信的成组多点广播路由算法

Group multicast routing algorithms for multimedia communication

多点广播是一源点传送信息到多个目的节点，成组多点广播是一组节点内部互相进行多点广播。成组多点广播的路由算法是为组内的每一个节点建立一棵路由树，用于点到多点的广播通信。本文提出一种新的成组广播路由算法，它比传统的成组广播路由算法在性能上有了一定的提高，同时更为简洁。

Multicast is a node sends message to a group of nodes.Group multicast is a group nodes where each member of group sends message to the other members.The routing algorithms for group multicast is to set up a set of routing tree each for a node.This paper proposed a novel group multicast routing algorithms,it is more concise and more optimal than the old method.
