基于快速切换的MIPv6与PMIPv6域间互通优化方案

摘要

Mobile IPv6(MIPv6) is a host-based protocol, while Proxy Mobile IPv6(PMIPv6) is a network-based protocol. The interactions between PMIPv6 and MIPv6 should be considered. Several proposed scenarios belong to hard handoff and cause long handover latency. An optimized scenario-Fast Handover for Interaction with MIPv6 and PMIPv6(FHIMP) was proposed. Comparison of the handover latency of the optimized procedure with the predecessor and the analytic result shows that the optimized procedures have an advantage in network performance.%移动IPv6是一种需要主机参与管理的移动管理协议,而代理移动IPv6不需要主机参与移动管理.在成熟的MIPv6环境下使用PMIPv6,需考虑二者互通问题.已提出的互通方案多属硬切换,没有考虑切换的时延.运用域内快速切换思想,提出一种优化的域间快速切换方案,并对比优化方案和已有切换方案的网络切换时延.分析结果显示,优化方案的性能更优.
