网络的移动管理协议——Proxy Mobile IPv6的信令开销分析

摘要

The Intemet Engineering Task Force (IETF) proposed a network based mobility management protocolPMIPv6 ( Proxy Mobile IPv6). PMIPv6 is different from host based mobility management protocols, whose signaling is transferred among several network entities excluding MN. In order to study the different characteristics of the host-based and the network-based mobility management protocols, the signaling cost of the mobility management protocol PMIPv6 and the host-based mobility management protocols of MIPv6, FMIPv6, HMIPv6, and F-HMIPv6was analyzed using an analytical model. The results show that the PMIPv6 protocol has a low signaling cost.%IETF提出了基于网络的移动管理协议PMIPv6,PMIPv6与现有的基于主机的移动管理协议不同,它的移动协议是在一些网络实体之间进行而不包括移动节点MN(mobile node).为了研究基于主机和基于网络的移动管理协议的不同特性,采用了分析模型的方法对PMIPv6及一些基于主机的移动管理协议的信令开销进行了分析,结果表明PMIPv6具有较小的信令开销.
