为解决全IP通信网络移动性管理的瓶颈——移动IP切换长时延的问题,在分析层次化移动IPv6系统的基础上.提出了基于根移动锚节点的移动IPv6(RM-MIPv6)切换方案.借助于根移动锚节点,保持了移动IP层次性管理域内切换的优势;通过低层移动锚节点功能实体的增加,有效地避免了由于集中式网络中心节点失效给网络带来的影响.对网络层快速切换的方案做出改进,使其达到根移动锚节点域内切换优化时延性能.
The long time-delay of mobile IP(MIP) mobile handover proposal based analysis to hierarchical MIPv6(HMIPv6)system is proposed to reduce the time-delay of MIP handover. The using of root mobility anchor point(MAP)keeps the advantages of MIP handover in hierarchical field, moreover, the adding of lower MAP avoids the influence by the failure of center node in centralized network. Through improving network layer(L3)fast handover mechanism, root mobility anchor point (RM)-MIPv6 proposal can achieve the optimal performance.
