摘　　要：在利用移动IPv6协议进行节点的移动性管理过程中,切换问题是影响管理性能的最关键因素之一。为了提高移动网络服务质量,需对移动IPv6切换性能进行优化。针对标准移动IPv6(MIPv6)的切换技术的种种弊端,在深入分析其切换时延的基础上,提出了一种新型MIPv6无缝切换模型——双接口移动终端辅助切换。新方案的特点是在一张网卡上集成两个无线模块,利用双链路将移动节点在不同子网间的切换转变为移动节点内部接口的切换,基本上实现了无缝切换。而硬件的成本正在不断降低,显然通过低廉的硬件冗余来换取高质量的移动网络服务是完全值得的。When mobile IPv6 executes the MNs＇ mobility administration, handsoft is one of the must important problems of affecting the administration. In order to improve the quality of service for mobile networks, the mobile IPv6 handoff performance must be optimized. Aimed at the various drawbacks of the standard MIPv6, analyses the handover delay of the standard MIPv6 deeply and proposes a new model of seamless handover- mobile assisted bandover with dual - interface. The idea of the new solution is that it turns the handover between different subnets into the switch of two interfaces in the mobile node by using dual - interface which achieved a seamless handover basically. With the hardware costs being lower and lower, high - quality services of mobile network is worth the low- cost hardware redundancy obviously.
