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。因此,需对移动IPv6切换性能进行优化,HMIPv6正是对移动IPv6进行优化的一种协议。但在HMIPv6协议中还存在域间切换问题,在分析了域间切换问题产生的基础之上,给出了主要解决的思路,并提出了基于提前绑定更新选项的HMIPv6域间无缝切换方案——S-EBUO,以优化移动IPv6切换延迟和分组发送延迟,最后利用NS-2网络模拟器仿真实验证明了方案的可行性和优越性。When Mobile IPv6 executes the MNs＇ mobility administration, handoff is one of the most important problems of affecting the administ ration. So the mobile IPv6 handoff performance must be optimized. The hierarchical mobile IPv6 （HMIPv6）, as an extension to the mobile IPv6, is just an optimization protocol. But there are the problem of the inter-domain handover of mobile nodes in HMIPv6 protocol. On the basis of analyzing the cause ofhandoffproblems, the methods of solving them is given, and an improved fast seamless handover scheme in the inter-domain of HMIPv6 network is brought forward, which based on early binding updates option- S-EBUO. The scheme is to optimize the handoffdelay and the delay of packet sending for mobile IPv6. Finally, a intuitionistic comparison of the proposed scheme using the network simulator NS is given, and in this way, the validity and superiority of the proposed scheme are proved.
