摘　　要：基于RFC2 0 0 2的移动因特网协议 (MobileInternetProtocol,MIP) ,解决了因特网协议 (InternetProtocol,IP)不支持节点跨子网漫游的问题 ,但要求移动节点必须具备动态修改路由表的功能 ;而在实际中广泛应用的操作系统 ,特别是Windows9x/Me等系统不支持对路由表的动态改变 ,这严重制约了移动IP的应用与推广 .本文提出了主动ARP(ActiveARP ,AARP)协议 ,并在此基础上设计了一种新的移动IP算法 .实验和分析表明 ,该算法在不引起性能下降的同时 ,克服了以往移动IP算法难以在Windows等系统上实现的缺点 ,极大扩展了移动IP的应用范围 ,并且易于实现、兼容性强、便于用户使用 .同时 ,虽然该协议主要是针对Windows系统设计的 。The mobile IP protocol based on RFC2002 can solve the problem that TCP/IP can't support a node roaming among subnets,only if the mobile node has the ability to modify its route table dynamically.While in practice,many typical operating systems such as Windows9x/Me etc.can't satisfy the above conditions,which restricts the utilization and the generalization of nobile IPseriously.So a new protocal--named active ARP(AARP) protocol,and the mobile IPalgorithm based on it have been proposed in this paper.Experiments and the analysis show that the protocol can be implemented on WIN platform easily and can be used by users more expediently with the performance not being deteriorated,which overcomes the disadvantage of the classical mobile IP algorithm that is hard to implement on Windows and extends the application field of mobile IPgreatly.Further more,the protocol can apply not only to windows but also to other operating systems.
