摘　　要：移动IPv6协议给出了支持主机移动的远程签署和家乡签署两种组播方法,它们具有互补的优缺点.提出的移动组播算法综合了这两种基本方法,同时采用区域的层次型结构的路由思想,减少因主机移动而重构组播树的频率,并对模拟结果进行了分析和比较.Mobile IPv6 offers two methods of multicast services for mobile host called remote subscription and home subscription, which have complementary advantages and shortcomings. An efficient mobile multicast protocol provided in this paper integrates remote subscription and home subscription. It uses a hierarchical route architecture, which reduces the frequency of rebuilding multicast tree because of hosts?mobility. The results of analysis and simulation are also given.
