文中主要针对移动IP中移动节点的定位透明问题进行了分析研究。分别使用NDM方法和反向隧道技术来解决该问题。针对两者的缺陷,提出了双向透明隧道的概念,在解决移动节点的定位透明问题的同时保证了移动节点和通信对端之间的双向通信。
In this paper, we mainly analyze and study the transparent positioning of mobile nodes in Mobile IP. Use NDM methods and reverse tunneling techniques to solve this problem. In view of the defects of both, a concept of bi-directional transparent tunnel is proposed, which solves the problem of positioning and transparency of mobile nodes and ensures the bidirectional communication between the mobile node and the correspondent node.
