摘要： 针对现有移动IP协议功能实现的局限性,研究了移动IP涉及的主要实体在移动过程中的行为,提出了一个基于移动IP的反向隧道功能实现的方法。该方法利用Linux提供的隧道机制,在Linux全用户空间中创建了一个能突破路由器入口过滤的移动节点反向隧道的功能函数,初步实现了移动节点离开家乡网络后的通信功能,完善了移动IP协议功能。

Abstract: Aiming at the limitation of the function realization of existed mobile IP protocol, this paper studies the behavior of the main three entities of mobile IP in mobile progress, proposes a method to realize the function of reverse tunneling for mobile IP. Using the tunneling mechanism provided by Linux, this method establishes a function of reverse tunneling for mobile node in the user space totally of Linux which can break through the Router’s ingress filtering, realizes the communication function for the mobile node after it left the home network and perfects the function of mobile IP protocol.
