HMIPv6切换协议的研究与改进
摘要
IETF提出了层次化移动IPv6技术(HMIPv6),它通过引入移动锚点(MAP),将网络进行了层次化的划分,使的移动分为宏移动和微移动。当移动节点在MAP域内发生微移动时,移动节点不用再向远方的家乡代理和通信对端发送地址绑定信息,从而减少了网络中注册信息的发送,进而减少了移动过程中的传输切换延时,提高了移动IPv6的通信质量。
本文主要是在分析层次化移动IPv6的基础上,指出该协议中存在的几点不足之处,如;MAP选择的问题,MAP负担过重,路由优化等问题。针对这几点不足之处,本论文提出了两种方案来解决;(1)对HMIPv6的MAP发现协议进行扩展,让移动节点结合自身的移动特性和MAP的因素,并依据一定的MAP选择算法,来选择适合移动节点的MAP,最终达到尽量让移动节点发生微移动,从而减少传输延迟。(2)引入了边界网关来分担MAP转发数据包的功能。通过MAP向边界网关发送有关移动结节点的位置信息,边界网关能直接将数据包发送到移动节点,从而解决了MAP的负担过重问题.并实现了路由优化,最终减少了网络传输延迟。本文的最后就这两种方案在Linux下做了实现。
IETF has brought Hierarchical Mobile IPv6 technology (HMIPv6) , which divides the whole network into many layers by importing Mobile Anchor Point(MAP)o This division make mobile into two types-Macro Mobility and Micro Mobility. When the mobile node happens Micro Mobility in a MAP, It has no longer to send the address binding messages to Home Agent and Correspond node, which reduces the registration messages sending and the delay of switching . Thereby, Improving the communication quality of MIPv6.
At the basis of analysing HMIPv6, The text mainly points out several defects in the HMIPv6. such as: Selection problem of MAP, overweight burden of MAP, the Route optimization problem, point to these defects, the text have brought two kinds of resolution schemes: (1) Extend the MAP foudation protocol of HMIPv6. Through union Mobility Node self's moving characteristic property, MAP factor and sepcial MAP choose algorithm, comes to choose MAP which is fit for Mobile Node, ultimately making Mobile Node utmost do Micro Mobility and reduce the transmission delay. (2) Introduce The Border GateWay sharing in the MAP transmission messages, Through sending the address binding message of Mobile Node to Border GateWay, the Border GateWay can directly send the messages to Mobile Node, which resolves the overweight burden problem of MAP, realize the Route Optimization , and finally the text provides two schemes realization under Linux.
