组播技术从IP组播到应用层组播的发展,解决了IP组播部署困难的问题.应用层组播采用终端主机转发数据的方式,在一对多的媒体内容分发方面具有广阔的应用前景.由于终端主机灵活性高,可随意退出组播树,在传输数据时易中断的特点,因此需要解决应用层组播的稳定性问题.首先分析了影响应用层组播稳定的三个因素:节点的转发能力、稳定状态和节点间通信延时.其次根据这些约束条件抽象出T-DTD(Spanning tree based on degree-constrained,max on-session time and depth bound for ALM)模型,最后给出稳定度因子在T-DTD下的表达形式,并据此提出一种适用T-DTD模型下的DTD-H(DTD-heuristic)算法,模拟实验证明...

The development of multicast technology from IP multicast to application layer multicast has solved the problems associated with IP multicast. Application layer multicast （ALM） which uses independent terminals hosts to relay multicast data has a prosperous prospect in one-to-many media content distribution. Because of the high flexibility of the terminal host, it is easy to quit the multicast tree and is easy to interrupt when data is transmitted. Therefore, it is necessary to solve the stability problem of application layer multicast. Firstl...
