| 摘 要： | 针对现有多播协议均忽略代价不对称性建立共享多播树这一问题,分析并设计了一种基于源端建立多播树的算法,并实现了与之相关的支持轻量级应用的应用层多播协议.基于本协议开发了一套应用层多播聊天程序,并在校园网上进行了实验.结果表明,所设计的应用层多播机制能有效地支持小规模的多播通信.

| Abstract: | The present multicasting protocols all neglect the asymmetry of link cost in establishing share multicasting tree.For this reason,a tree-building algorithm based on source end is presented.A set of multicasting protocols relating to the algorithm that support the lightweight application are designed and realized.Also,an application-level multicast chat program based on the multicasting protocol is successfully developed.The experimental results in the campus-wide Ethernet show that this multicast algorithm is available and can efficiently support the small-scale multicasting communication. |
