Study the Handoff Management of Mobile Ipv6 Network Based on Mpls

According to handoff management problem of mobile IPv6 network, when the mobile node accesses field network and leaves home network, to switch link, it will appear the decline of quality of service or business interruption. Accordingly, the paper proposed a hierarchy of handoff management scheme for the integrated multi-protocol label switching in mobile IPV6 network. With analysis on architecture and working principle of the MPLS technology, we listed common switching methods for the current mobile IPV6 network, switching process and performance for the standard mobile IPV6 network. By introducing the regional anchors, the burden of end node registration information processing for the home agents and communication on hierarchical switching optimization was reduced, thereby the registration delay and handoff delay was reduced, and the switching performance was improved. The theoretical analysis and computer simulation show that, the switching delay of proposed scheme is smaller than that of a standard mobile IPV6, which will better support high speed mobile for the host.
