移动IP网络层切换改善方案的研究

摘要

移动IP切换的长时延已经成为未来全IP网络移动性管理的瓶颈.为解决这个问题,在分析层次化移动IPV6系统的基础上,提出了改进的移动切换方案.借助于根移动锚节点(RMAP),保持了移动IP层次性管理域内切换的优势;对网络层快速切换的方案做出改善,结合MN在网络中的位置实施了最优路由器广播周期逐层配置,使其达到RMAP域内切换最佳时延性能.%The long delay of MIP handoff has been the bottleneck of mobile management in all IP networks in the future. To settle this problem, on basis of analysis to MIPv6 system, the improving mobile handoff project was brought up. The using of root MAP keept the advantages of MIP handoff in hierarchical field.Through improving L3 fast handoff mechanism, the improving project can achieve the optimal delay with the setting of the best router advertisement period by layers.
