摘　　要：针对目前移动IPv6环境下的IntServ/RsVP模型在处理移动节点切换时的不足,本文提出了一种基于层次化移动管理的流透明移动IPv6 QoS模型,简称为HMMFT移动IPv6 QoS模型。这种模型显著地减少了移动节点发给通信节点与家乡代理的绑定更新消息,提高了MIPv6的切换速度,同时基于移动节点的区域转交地址来标识流,实现了域内切换的流透明。本文的最后利用NS2对HMMFT移动IPv6 QoS模型性能的优越性进行了仿真分析。Because the existing mobile IPv6 IntServ/RSVP model lacks the ability to handle mobile node's handoff, this paper introduces a new Mobile IPv6 QoS Model, named Hierarchical Mobility Management-based Flow Transparent Mobile IPv6 QoS Model(the HMMFT Mobile IPv6 Model). The hierarchical mobility management will reduce the amount of signaling to correspondent nodes and the home agent and may also improve the performance of MIPv6 in terms of handoff speed. The HMMFT Mobile IPv6 Model identifies a flow based on the regional care-of address, thus implements flow transparent when mobile node performs a handoff in a MAP domain. At last, we also analyze the performance of this model using the Network Simulator 2(NS2).
