摘　　要：随着Internet和无线数据技术的发展,移动虚拟专用网(MVPN)技术越来越受业界关注。MVPN把虚拟专用网(VPN)扩展到无线接入环境与无线数据应用结合,是建立在移动网资源上的虚拟专用网络,由移动IP(MIP)支持终端的移动性,使远程移动用户能简单、安全、高速地访问企业内部的网络资源。文中介绍了MVPN的基本概念及基于IP安全协议(IPSec)的MVPN基本原理,讨论了端到端自愿型隧道MVPN和基于网络的强制型隧道MVPN的实现方法和原理,最后对MVPN的市场应用进行了简要分析。With the concurrent evolution of Internet and wireless data technologi es, MVPN(mobile virtual private network)are gaining more and more attention in t he industry. Combining with wireless data applications, MVPN is a VPN(virtual pr ivate network)built upon mobile network resources, which extends VPN into the wi reless access environment. The mobility of terminals in MVPN supported by mobile IP offers simple, secure and high speed access to network resources within the enterprise for remote users. This paper introduces the basic concept of MVPN and the basic principle of IPSec-based MVPN. Then, the implementation of end-to-end voluntary tunnel MVPN and network-based compulsory tunnel MVPN are discussed. F inally, market application of MVPN is briefly analyzed.
