摘　　要：针对层次移动IPv6宏切换中丢包率高、切换延迟大的问题,提出一种将隧道机制应用于层次移动IPv6的优化方案(TBFMH)。TBFMH根据切换信息提前获得转交地址,进行重复地址检测,并在建立隧道的同时完成本地绑定更新。仿真实验表明,TBFMH比层次移动IPv6至少减少50%的切换延迟,同时降低了丢包率,有效提高了移动节点进行宏切换的性能。The macro handover has caused high packet loss and long handover latency in Hierarchical Mobile IPv6（HMIPv6） protocol.To solve these problems,this paper proposed a protocol named Tunnel-based Fast Macro-Handover（TBFMH）,which introduced the mechanism of tunnel,acquired care-of addresses on the grounds of handover information,conducted duplication address detection in advance and completed local binding update while building the tunnels.The simulation results show that TBFMH can decrease the handover latency by 50% at least and reduce the packet loss rate compared to HMIPv6,which effectively improves the performance in the macro handover.
