摘　　要：P2P视频直播系统对实时性要求较高,而在P2P系统中,组成组播树的节点是自主的终端主机.终端主机的频频离开会造成组播树的不稳定.本文提出一种稳定的应用层组播树生成算法,并在组播树上部署冗余虚拟链路.模拟实验表明,该算法具有明显的稳定效果.Live streaming system for real-time P2P demands higher requirements, while in P2P systems,the application level multicast tree is composed of the free end hosts. The end hosts constantly left will lead to the instability of the application level multicast tree. This paper proposes a stable application level multicast tree construction algorithm,the redundant virtual linke was deploymerized in the multicast tree. Simulation experiments show that the algorithm has obvious effect of stability.
