摘要： 在分析原有HMIPv6(HierarchicalMobileIPv6)网络架构的基础上提出了一种新的网络架构——多连接度的多层移动IPv6网络架构,并论证了新网络架构在一定程度上解决了原有网络架构中存在的根节点的瓶颈问题和提高了原有网络的鲁棒性。新网络架构中移动节点存在多级多个上层节点,针对如何具体选择某个上层节点作为移动节点的MAP和EGW,论文提出了一种选择算法,并且通过具体例子计算说明了该算法有效性。

Abstract: This paper describes the new network framework based on HMIPv6.The new network framework is a multi-degree network framework for hierarchical mobile IPv6.By theoretic analysis,the paper proves the new network frame can solve the problems that root node is a bottleneck in old HMIPv6 and improves the robust of mobile IP.It brings forward a new arithmetic to choose two nodes as mobile node’s MAP and EGW in the multi-degree and multi-hierarchical network framework.Practical experience proves that the arithmetic is effective.
