移动IP原理浅析

Analysis of Mobile IP Principle

详细描述了移动IP的工作过程与机制,并介绍了移动IP实现的关键技术,最后对IPV6中移动IP新特性进行了论述.提出移动IP功能实体及隧道、家乡代理、转交地址等相关概念,然后对移动IP的做了详细的介绍,从而解决了Internet的可扩展性依赖于网络前缀路由和固定网络中的网络前缀路由技术没有办法将数据包发送到节点的新位置上的问题.最后总结了移动IP目前存在的问题和不足.

Mobile IP is a technique for solving the problems of nodes movement on Internet. It＇ s also a focus of research in the present Internet technology. The working process and mechanism of mobile IP were described, together with the key techniques to implement it. New properties of IPv6 in mobile IP technology were discussed. The concepts concerning mobile IP were put forth such as function entity, tunnel, home agent and delivery address. Detailed introduction was given to mobile IP. The problems were solved that the Internet expansibility depends on the prefix router, and the prefix router can＇t send the data packet to new node address. Disadvantages and shortcomings of mobile IP were summarized.
