Mobility label based network: Support for mobility using MPLS and Multi-Protocol BGP

To support mobility the network control plane is required to detect changes in the mobile node’s location and distribute the new location information thus enabling the forwarding plane to deliver traffic in an optimal manner. This paper introduces a new mobility management protocol for mobile node registrations and movement handling based on the MPLS architecture and new elements in MP-BGP to achieve Mobility Label distribution at the network control plane and the optimal packet delivery by the network forwarding plane. This approach does not rely on Mobile IP and results in the elimination of triangular routing and the associated user facing performance penalties.
