PMIPv6的跨域切换机制的研究

Study on the cross domain switching mechanism of PMIPv6

作为一个基于网络的区域移动性管理协议,PMIPv6允许移动终端在没有移动信令控制的情况下,在局限网域服务中漫游.然而,PMIPv6只能在一个局限网络访问域中保持对移动终端的移动性支持.于是,当移动终端离开了一个PMIPv6访问域时,它的连接中断,通信过程中会产生一系列协议切换、延时及不可避免的网络丢包问题.本文将对PMIPv6基本功能及相关的跨域移动性机制进行研究和分析,对各机制在性能上进行评估分析,为对进一步提升PMIPv6跨域切换性能的研究打下基础.

As a network-based localized mobility management protocol, Proxy Mobile IPv6（PMIPv6） enables a Mobile Host（MH） to roam within a localized domain without MH intervention in the mobility-related signaling. Therefore,whenever the MH roams away from the PMIPv6 domain, its reachability status will be broken-down causing high handover latency and inevitable traffic loss for its communication session. In this paper, we will study and analyze the basic function of PMIPv6 and the related cross domain mobility mechanism, evaluation and analysis of the performance of the mechanism, in order to further improve the performance of the PMIPv6 cross domain switching.
