中文摘要：

基于分层移动IPv6的体系结构,提出了一种用于解决组播信宿移动的路由算法.结果表明,通过使用分层结构、本地隧道和域内组播,新算法具有最优的组播树重构率,次优的组播服务中断延迟、目的地传输花费和网络传输总花费.因此它具有很好的应用前景.

英文摘要：

Based on the architecture of hierarchical mobile IPv6, a hierarchical mobile multicast （HMM） algorithm is proposed to resolve the motion of multicast receiver. By using hierarchical structure, local tunnel and inner multicast, the results of simulations show that the rebuild ratio of multicast tree is decreased in HMM. As the same time, delay of recovering multicast service, average transmission cost to destinations and total transmission cost of entire multicast network in HMM are near-optimal, which has good application foreground.
