构建移动互联网的新IP体系研究

传统的基于IEFT RFC2002的Mobile IP协议及其后续版本RFC3344、RFC3775都无法从根本上彻底解决＂三角路由＂和切换延时问题。本文从网络层的协议框架出发,构建一种支持移动网络环境的新移动IP地址方案,并采用基于门限值的软切换技术,可以很好地解决＂三角路由＂和跨区漫游的延时问题。这一新框架下的细节问题还有待进一步探索和研究,本文仅从移动节点跨区直达路由和无缝切换问题上进行分析。

Study on New IP System for Construction of Mobile Internet

Traditional mobile IP protocol based on the IEFT RFC2002 and the follow-up versions such as RFC 3344 and RFC3775 can not solve ＂triangular routing＂ and switching delay problem. This paper sets out the network layer protocol, and builds a new IP address structure that supports the environment of Mobile network, And threshold-based soft switch technology to solve the problem of ＂ triangular routing＂ and cross-roaming delay. The detail of the framework requires to be further researched, and the paper has only engaged in the analysis from the issue of direct routing and seamless handoff for crossing domain of mobile nodes.
