摘　　要：本文主要探究了移动PI-HMIPv6快速切换技术的基本原理和运行流程。采用对照试验方法,使用网络仿真器NS-2软件搭建仿真环境,设定好仿真参数后,对比了MIPv6、HMIPv6和PI-HMIPv6三种协议下移动节点的切换时延。仿真结果表明,移动节点无论是在域内切换还是在域间切换,PI-HMIPv6的切换时延均维持在300~500 ms之间,明显低于MIPv6和HMIPv6。由此可得,移动PI-HMIPv6快速切换技术能够将切换时延维持在较低水平,满足了通信业务的实时性要求。This paper mainly explores the basic principle and operation flow of mobile PI-HMIPv6 fast switching technology.A control test method was used to build a simulation environment with NS-2 software,and after setting simulation parameters,the handover delay of mobile nodes under MIPv6,HMIPv6 and PI-HMIPv6 protocols was compared.The simulation results show that the switching delay of PI-HMIPv6 is between 300 and 500 ms,which is significantly lower than that of MIPv6 and HMIPv6.It can be concluded that the mobile PI-HMIPv6 fast switching technology can keep the switching delay at a low level,and meet the real-time requirements of communication services.
