摘要
设计了一种网状优先的应用层组播拓扑,将分发节点组成局部Cluster后,再将Cluster组建为一个层次化树形拓扑结构,并在此层次化树形集群系统基础上建立组播树.为多个组播数据源在此共享拓扑上建立起不同的最短路径组播树,实现应用层组播.
A mesh-first application level multicast topology for live-streaming CDN is proposed to support multiple source specific trees with one single topology.This topology organizes the multicasting nodes into an administrative hierarchy of clusters,and it builds routing trees atop this hierarchy.
