Performance Analysis of the Proxy Mobile IPv6 (PMIPv6) and Multiprotocol Label Switching (MPLS) Integration

This article analyzes and develops the integration of the PMIPv6 (Proxy Mobile IPv6) and MPLS (Multiprotocol Label Switching) protocols in order to determine the impact at the time of handover in an IP micro mobility environment. The proposed integration suggests the establishment of abidirectional Label Switched Path (LSP) between the Mobile Access Gateway (MAG) and the Local Mobility Anchor (LMA), in order to replace the IPover-IP tunnels that support PMIPv6. The proposed integration is a semi-soft integration, and NS-2 is used to evaluate the impact of introducing MPLS technology in a PMIPv6 domain. PMIPv6/MPLS was compared with PMIPv6. The results indicate an improvement in the performance of the handover, when PMIPv6 and MPLS integration is used.
