摘要： 分析标准移动IPv6(MIPv6)的快速切换机制，提出一种基于邻居信息表的移动IPv6快速切换解决方案。通过预配置和定时更新的方法使移动节点提前获取将要进入目标有限区域的信息表——邻居信息表，从而缩短切换中过程转交地址唯一性验证时间及移动检测延迟时间，降低切换过程中的丢包率。仿真结果表明，该机制不额外占用网络资源，能够减少切换过程中的丢包率和切换延迟时间。

Abstract: The standard Mobile IPv6(MIPv6) fast handoff scheme is analyzed. A neighbour information table-based fast handoff scheme for MIPv6 is proposed. Through pre-configured and regularly updated way to let Mobile Node(MN) get ahead of target limited areas of information table, called neighbour information table. It switches process with a neighbour information table to shorten the uniqueness of the care-of address verification and testing of time delay, reduce the packet loss rate in the handover process. Simulation results show this mechanism does not take up additional network resources. It reduces the packet loss rate and cuts down the switching process of switching delay time.
