摘　　要：为了提升移动IPv6快速切换(FMIPv6)的性能,在研究FMIPv6协议的基础上,提出一种基于路由器信息缓存的快速切换方案。该方案中,移动节点通过建立和更新路由器信息缓存表,存储其运动中访问的路由器历史记录,从而减少移动节点进行转交地址配置和重复地址检测的延迟。仿真结果表明,该方案中移动节点在重复访问历史路由器时,能有效缩短切换时延,减少切换过程中的数据分组的丢失率。On the basis of research on fast handover for Mobile IPv6 （FMIPv6） protocol, this paper proposes an improved scheme which introduces a mechanism of access router caching information to improve the performance of FMIPv6. In this scheme, it is to create and update router information caching table in the mobile node, which stores the information of all the access routers that mobile node has connected in the past. Then the latency of care-of address（CoA） configuration and duplicated address detection （DAD） procedures is reduced significantly. Simulation results show that this scheme can decrease handover latency and the packet loss when mobile node access the router which has been connected in the past.
