摘要
在应用层组播设计中,如果分发树的构造过程忽略了底层的网络拓扑结构和链路特征,则多播性能将会很差。该文采用一种定位算法,在不引入过多开销的情况下,将靠近的节点集中在一起。在此基础上,可建立一个拓扑敏感的分层应用层多播体系结构。
An application-level multicast may suffer from poor performance when the deliver tree construction process ignores the topology and link characteristics of the underlying network. This paper uses locating algorithm gradually to direct newcomers to a set of their closest nodes without inducing high overhead. On the basis of this locating process, a topology-aware clustered hierarchical application-level multicast architecture will be designed.
