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 be-tween 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.
