M-MPLS: Micromobility-enabled multiprotocol label switching

This paper presents the integration of multiprotocol label switching with hierarchical mobile IPv6. The resulting micromobility-based MPLS (M-MPLS) is defined in two modes of operation: overlay and integrated. In an overlay framework MPLS and HMIP operate on their respective layers without having common processes, tables, or signaling. In an integrated framework, related functions are merged. The overall goal of an integrated framework is to facilitate efficient and reliable network operations while simultaneously optimizing network utilization and system performance.
