一种新的移动IPv6移动性管理策略

A New Mobility Management Scheme for Mobile IPv6

在IETF制定的移动IPv6移动性管理策略中 ,当移动主机每次从一个子网移动到另一个子网时 ,都需要对家乡代理和相应的通信主机进行绑定更新 ,这就导致网络总的绑定和发送代价过高 .本文提出了一种新的移动性管理策略 ,在利用现有网络结构的基础上 ,通过将移动主机的移动分为本地移动和家乡移动两种类型 ,来减少移动主机向家乡代理和相应的通信主机发送绑定更新消息 ,从而降低网络的绑定代价 ,使网络的性能得到改善 .

According to the Mobile IP mobility management scheme proposed by IETF,a mobile host must update its home agent and correspondent hosts whenever it moves from a subnet to another.This will result in the high binding and delivery costs in the networks.In this paper,we present a new mobility management scheme,which can reduce the binding and delivery costs and improve the performance of the network by detecting local movement and home movement to decrease the number of binding and updating messages sent to its home agent and correspondent hosts,on the base of the current network architecture.
