| 摘 要： | 移动组播是移动互联网络技术的一个研究热点,但现有移动组播方案存在着组播中断时间长、协议开销大等问题.针对这些问题,该文提出了一种基于MLD代理的移动组播方法.该方法在家乡代理上实现简化MLD代理功能,减少协议开销;在移动节点上扩展MLD功能,减少组播中断时间.另外,为了解决移动组播隧道聚合问题,还提出了一种隧道合并重构机制.通过理论分析计算了该方法的组播中断时间和协议开销.结果表明,同其他移动组播方法相比,该方法能够缩短组播中断时间,减少协议开销.

| Abstract: | Mobile multicast is a research hotspot of mobile network,but most of mobile multicast schemes suffer from the long multicast disruption time and heavy protocol cost.So,in this paper,a MLD(Multicast Listener Discovery)Proxy based mobile multicast scheme for IPv6 was proposed,this method implemented simplified MLD-Proxy on home agent to reduce the cost and extended MLD host part function on mobile node to shorten the multicast disruption time,Besides,to solve the tunnel convergence problem,it also introduced a multicast tunnel combination and reconstruction mechanism by extending the mobility support specification.To evaluate the performance,the multicast disruption time and cost of the proposed scheme were analysized.Compared with the other schemes,the results shown that the proposed scheme improved the multicast disruption time and reduced the cost. |
