代理移动IPv6下子网移动方案的实现与分析

Implementation and analysis of network mobility under proxy mobile IPv6

代理移动IPv6是基于网络的移动性管理方案,其标准RFC5213中只规范了对单个节点的移动性支持,缺乏对子网移动的研究。研究了现有的3种代理移动IPv6下基于隧道的子网移动方案,重点分析了代理移动IPv6下采用隧道分离思想的移动子网实现方法 N-NEMO(network based NEMO),并在Linux环境下采用C语言对3种方案分别给予实现,对3种子网移动方案进行性能分析和对比,结果表明,虽然N-NEMO的切换时延较大且信令较为复杂,但是具有网络层头部开销小及支持节点类型全面的优点。

Proxy Mobile IPv6 （PMIPv6） is a network-based mobility management scheme. Its standard RFC5213 only sup- ports host mobility but not subnet mobility. In this paper, we investigate three existing subnet mobility schemes based on tunnel under PMIPv6 and analyze N-NEMO（Network based NEMO）which adopts split tunnel. We perform three schemes using C language in Linux. By analyzing and comparing the three schemes, we obtain that although N-NEMO has large de- lay and complex signaling, it has the advantage of low network layer header and can support more node types.
