摘要
移动IP组播技术是移动IP技术和组播技术的结合,有广泛的发展空间。该文对MMA(移动组播代理)算法进行适当的改进后,给出了一种在移动IPv6环境下的移动组播算法。该算法把MMA算法的思想引入到移动IPv6环境中,同时采用基于区域的分层结构,并且在节点移动时采用在移动代理间建立隧道的方法补充数据包,减少了组播树的频繁重构,提高了组播可靠性。对比移动IPv6环境下的双向隧道和远程签署两种移动组播算法,该算法具有较好的综合性能。
Mobile IP multicast technology,the combination of multicast technology and mobile IP technology,has wide develop ment space.A mobile multicast algorithm based on mobile IPv6 is introduced in the paper,which is an improved algorithm based in mobile multicast agent algorithm used in mobile ipv6 environment.While node is moving,a layered structure based on loca tion is brought in the new algorithm to improve multicast reliability by building tunnel between MAs and reduce frequent recon struction of Multicast tree.Comparing two basic mobile multicast schemes-Bi-directional Tunneling(BT)and Remote Sub scription(RS),the improved algorithm has good comprehensive performance.
