Next generation MPLS-based wireless mobile network

The next generation Internet based on multiprotocol label switching (MPLS) and integrated services architecture will likely emerge as a prominent core network for future generation wireless mobile systems. This paper proposes a lightweight near-seamless handoff scheme to support terminal mobility over a MPLS-based Internet supporting performance guarantees. The handoff scheme is supported by: (1) a novel mobile label switched tree (MLST) architecture which provides dynamic mobility tracking and adaptive traffic rerouting during handoffs; and (2) an extended RSVP to enable fast and robust resource reservation during handoffs.
