Fast Handover Policy Research In Mobile IPv6Network

In the mobile communication process, Mobile IPv6(MIPv6) protocol has a certaindegree of good operability, it accelerate the application of the switch by the user usingthe mobile terminal, but it will still extended in three phenomenon:in the configurationof the movement detector, a new care-of address, binding update; at the same time, themobile node handover performance requirements are increasing as some of the real-timerequirements of the business.Therefore, IETF organization proposed fast mobile IPv6(FMIPv6) protocol, Hierarchical Mobile IPv6(HMIPv6) protocol and fast hierarchicalmobile IPv6(FHMIPv6) of protocol.This article analyzes MIPv6and FMIPv6switching mechanism, to implementswitching strategy through simulation tests, and proposed security solutions combinedMPLS. Simulated during the simulation analysis by using the TCP protocol set FTPservice data flow, the UDP service data flow and performance in simulated TCPtransport layer protocol; And the article analyzes the TCP performance in the peocess ofswitching nodes in a wireless network environment from three aspects: first, analysefour kinds congestion control algorithmof TCP in the cable network; second, analyse thetransmission performance of TCP in a wired network;third, analyse the performance ofTCP in a mixed network of wireless nodes and wired network.MIPv6communication mechanism based on MPLS protocol, made a goodcombination of MPLS and MIPv6, improve the handoff efficiency of MIPv6, enhancethe security of MIPv6in the handover process. MIPv6based on MPLS protocol reducethe switching process switching delay time, optimize the handover process, thecommunication process become more secure and reliable, enhanced MIPv6on adaptingof the wireless applications higher confidentiality through simulation analysis.This paper verify the TCP performance improved in the process of switching thepacket loss, throughput indropped,and moving of MN，through analysing the MIPv6protocol on the use of TCP protocol data stream transmission performance analysis andsimulation, and analyse the transmission delay, dithering, packet loss rate, throughputcomparative analysis of the parameters.
