| 摘 要： | 以移动IP作为网络层路由支持向移动主机提供多播技术是一个巨大的挑战。首先对基于IP网络模型的移动IP和IP多播技术做概括论述，分析了IP多播的算法和多播路由协议。然后侧重研究在目前的移动IP中如何有效提供多播技术的支持，分析了在现有的IP网络中集成多播和移动性时出现的问题，阐明了几种可能的机制并比较了各自的优缺点。最后提出了一种改进的基于移动IP的移动主机多播技术支持，并和其他方案进行了比较。

| Abstract: | It is a great challenge to provide multicast to mobile hosts using mobile IP for network routing support.In this paper,we first make some analyses and researches on mobile IP and IP multicast based on IP network mode,then,we place great emphasis on the provision for handling multicast in the current mobile IP specification,and analyze the problems when combining multicasting and mobility in the existing IP network,including comparing several mechanisms and analyzing their respective problems.At last we provide and improved architecture to support IP multicast for mobile hosts using mobile IP,and compare it with the introduced mechanism. |
