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。
In order to deal with the shortage of mobile node switching when IntServ / RsVP model in mobile IPv6 environment, this paper proposes a transparent Mobile IPv6 QoS model based on Hierarchical Mobile Management (referred to as HMMFT Mobile IPv6 QoS model for short). This model significantly reduces the binding update message sent by the mobile node to the correspondent node and the home agent and improves the switching speed of the MIPv6. At the same time, the flow is identified based on the care-of address of the mobile node and the flow of the intra-domain handover is transparent. In the end, this paper uses NS2 to simulate the superiority of HMMFT Mobile IPv6 QoS model.
