移动通信与Internet的互联是移动通信的发展趋势,于是一种新的支持移动用户与Internet连接的互连技术———移动IP技术应运而生。隧道技术是移动IP技术的重要内容。本文详细介绍了移动IP的三种隧道技术———IP内IP封装、最小封装和通用路由封装,并且对这三种隧道技术进行了比较。
Mobile Internet and the Internet is the development trend of mobile communications, so a new mobile Internet users to support the Internet connection technology --- Mobile IP technology came into being. Tunneling technology is an important part of Mobile IP technology. This article describes in detail the three mobile IP tunneling technology - IP IP encapsulation, minimum encapsulation and generic routing encapsulation, and compares these three tunneling techniques.
