摘要: 为了提升移动IPv6域间切换的性能,在FHMIPv6的机制上提出了一种基于边缘接入路由器的域间移动管理方案。在这种方式下,移动主机在移动到边缘接入路由器上时,进行域内切换并把链路转交地址在前移动锚点和新移动锚点上同时进行重复地址检测;完成切换后,在边缘接入路由器域内对新区域转交地址进行配置并在新MAP中与链路转交地址绑定。通过NS-2实验仿真验证能够有效减少域间切换带来的延迟,同时也降低了分组的丢失率。

Abstract: To improve the performance of inter-domain handoff in mobile IPv6, one kind of inter-domain handoff mobility management scheme based on edge access router was introduced in the FHMIPv6 mechanism.In this method, when Mobile Node (MN) moved to the edge access router, it did intra-domain handoff and duplicated address detection for on-link care of address both in previous Mobile Anchor Point (MAP) and new MAP.It would set the new regional care of address and had the two addresses banded in the new MAP after the handoff was finished.Finally, the NS-2 simulation and comparison results show that this scheme can effectively reduce the transmission latency and packet loss rate.

Key words: hierarchical mobile IPv6, edge access router, inter-domain handoff, network simulation
