摘　　要：RBMoM是一种综合了IETF的移动IP协议中远程加入和双向隧道两种基本方法、综合性能较优的移动多播协议。文中通过分析RBMoM移动多播协议中存在的问题,提出了DMSP共享机制,基于此机制实现了一个高效的移动多播方案。该方案有效地减少了网络中的多播通信量并降低了多播树的维护代价,却没有给多播数据传输带来太大的延迟。RBMoM is a mobile multicast protocol with good integrated performance, which integrates two basic methods called Remote Subscription and Bi-directional Tunneling in Mobile IP of IETF. The problems in RBMoM mobile multicast protocol were analysed, and a DMSP-sharing mechanism was proposed, on which an efficient mobile muhicast scheme was provided based. This scheme lessens efficiently multicast traffic in network, and reduces multicast tree maintenance costs, but does not cause multicast data delivery to incur too large delivery delay.
