摘　　要：IP组播中,最重要的就是组播路由算法,一个好的算法可以使实现简单、收敛速度快、修剪及嫁接效率高.介绍了基于RPF生成树的多路广播算法的优缺点,并给出了一种改进的多路组播算法,最后还给出了实现该算法的软件细节.The routing algorithm is the most important one in IP multicasting technology. A good algorithm should be executed easily, and it could also speed up the process of convergence, promote the efficiency of cropping and grafting. In this paper,a kind of multicasting algorithm based on RPF tree is introduce at first, then an improved multicasting technology of IP multicasting is presented, finally the software details about this algorithm are provided.

关 键 词：IP组播 RPF算法 CBT算法 IGMP协议 组播路由算法 多路广播算法
