摘要
在分析总结目前IP组播路由研究的主要成果基础上,提出了一个新的组播路由方案,按需分枝组播.它采用了一种全新的组播树维护方式,即组播树由树上的部分节点(关键节点)维护,不同于现有的组播树由所有树上节点维护的方式,从而节省了网络资源.
After analyzing and summarizing the main current research outcomes of IP multicast routing, a multicast routing algorithm called on-demand branching multicast is proposed. On-Demand branching multicast uses a new multicast tree maintenance method, in which the tree is maintained only by partial nodes or key nodes. That is different from the traditional methods in which the tree is maintained by all the nodes on the tree, and so as to save the Internet resources.
