摘　　要：针对层次型移动IPv6网络的域间切换中的切换延迟和丢包问题,提出一种使用转交地址池改进原来DAD的检测方法来减少切换延迟,采用双路径通信方式降低丢包率的域间切换的改进方案。理论分析改进前后的切换延迟,使用NS-2工具对改进协议进行仿真。实验结果表明,改进方案在切换时延和丢包率方面表现出较好的优越性。Aiming at the problem of handover delay and packet loss, which existed in hierarchical mobile IPv6 networks, a new handover scheme was proposed. According to improving the technology of duplicate address detection by using care-of address pool, delay time could be reduced. Double communicate path was built in the networks, which was used to reduce the packet loss rate. By using the method of mathematical analysis, the delay before and after improvement was analyzed. NS-2 was used to simulate protocol, and the result of analysis proved the superiority of the improved scheme in terms of delay and packet loss rate.
