  Hierarchical Mobility Label Based Network (HMLBN) is a new approach to the
network layer mobility management problem that relies on MPLS-aware control
plane and MPLS-based forwarding plane to provide IP mobility support for IPv4
and IPv6 mobile hosts and routers while being able to ensure optimal traffic
delivery between the communicating devices. The hierarchical system is capable
of both macro- and micro-mobility support without the use of Mobile IP and its
derivatives thus eliminating the user and network facing performance penalties
associated with triangular routing and bi-directional tunneling. This paper
presents a system model and provides performance analysis for H-MLBN and
compares its performance with the Mobile IP based schemes. The results indicate
significant performance improvements in the forwarding plane traffic delivery
as well as the control plane network update costs.
