Research On MPLS-based Mobile IP

"Mobile IP services over MPLS" is now a hot spot to communications industry and some international organizations have already begun to set the standard, which only support mobile host. So how does MPLS support the MIP network, this is the key point of this paper.ITU–T recommendation Y.MIPoMPLS proposes that the interface from LER/MA to mobile network emulates the mobile node, but it lacks the detailed procedures. This paper first briefly introduces MPLS, mobile IP and "mobile IP services over MPLS", which are the theory bases of "MPLS support the mobile IP network". Then, the detailed implementations of MPLS support mobile IPv4 network scheme and MPLS support mobile IPv6 network scheme are proposed. Thirdly, the detailed implementation of MPLS support MIP network route Optimization and hierarchical MPLS support VPN network scheme are also proposed which on the basis of the last two implementations.The simulation of MPLS support MIP network is completed under NS-2 platform, but part of NS-2 components do not support MIPoMPLS, so MIP module is extended to support mobile router, MPLS module is modified to process specially the MIP register message and MRoMPLS is added to combine or merge functions of the home agent and the foreign agent into the MPLS node. Finally, the feasibility of MPLS support the MIP network is validated and some performance of that scheme is analyzed in detail.
