摘　　要：在移动IPv6网中,移动节点在不同子网间移动时产生切换,由此产生的延时和丢包问题限制了移动IPv6的应用。可见,移动IPv6切换技术的研究刻不容缓。概述了移动Ipv6切换技术的发展情况及其工作原理,详细阐述了几种基本的改进切换技术,并在此基础上对三种针对时延改进的切换技术进行时延分析。通过分析,可以看出这三种改进的切换技术确实能有效减少切换时延,从而提高切换性能。其中,层次型快速切换是最能减少切换时延的一种方法。In the mobile IPv6 network,mobile node will produce handovers when it moves among different sub networks. The problems of delaying and losing data packets limit the application of mobile IPv6. Research on handover based on mobile IPv6 is no time to delay. Summarize the developing and working-principles of mobile IPv6 handover. And then recount particularly the basically improved handover technologies. On this basis,analyze the delay of three improved handover technologies which have been improved aiming at decreasing delay. By analyzing, can know that all the three technologies can decrease delay, and can improve handover-performance, and the hierarchical fast mobile IPv6 handover is the most effective method.
