基于节点状态的应用层组播算法

摘要

提出一种综合考虑节点能力和在线时间的应用层组播树生成算法,通过动态地对组播树中的节点进行交换的方式,让具有更强节点性能和更稳定在线时间的节点接近组播树的源节点,达到降低组播树中断频率的目的.%This paper proposes a generation algorithm of application layer multicast ( ALM) tree which takes into account the peers' ability and the online time. The algorithm moves the peers with higher performance and longer online time close to the media source of the multicast tree by the approach of dynamically exchanging the peers in multicast tree for the purpose of reducing interruption frequencies in multicast tree.
