摘　　要：层次移动IPv6协议中,链路转交地址和区域转交地址的重复地址检测操作需要的时间占IP层切换延时的绝大部分。提出了一种层次移动IPv6改进协议,引入链路转交地址池和区域转交地址池,从地址池直接获取转交地址,避免了重复地址检测操作。实验表明,相比层次移动IPv6协议,有效缩短了切换延时。In Hierarchical Mobile IPv6 （HMIPv6） protocol, the Duplicate Address Detection （DAD） operations for the On-link Care-of Address （LCoA） and Regional Cam-of Address （RCoA） greatly impair the mobile node＇s inner-MAP and inter-MAP handover performance. The HMIPv6 protocol based on care-of address pool which introduced LCoA pool and RCoA pool into HMIPv6 was proposed, care-of addresses were got from the pools directly, and therefore the DAD operations for the LCoA and RCoA were avoided. The experiment results show that the proposed protocol greatly reduces the handover latency.
