Using Fake Registration to Pre-Establish Routing for Improving Handover Performance in Mobile MPLS Networks

Abstract

Multi-Protocol Label Switching (MPLS) can setup a particular forwarding path to destination by label switching. It will speed up packets delivering. Shortening the time of LSP establishment for mobile nodes (MN) will fasten handover procedure and reduce latency. There are several ways used for rapid restoration of connectivity, but they can not support fast MN Multi-Protocol Label Switching (MPLS) can setup a particular forwarding path to destination by label switching. It will speed up packets delivering. Shortening the time of LSP establishment for mobile nodes (MN) will fasten handover procedure and reduce latency. There are several ways used for rapid restoration of connectivity, but they can not support fast MN efficiently. In addition, routing path is not always setup and maintained in stable situation. Generally, unstable routing path may have a higher maintenance cost and is unable to offer a QoS (Quality of Service) compared to the preferred path. In this paper, we proposed a pre-established with fake registration routing scheme called PEFRR to reduce the handover latency for rapid moving of mobile nodes. In mobile MPLS networks, the "Fake Registration" process will be performed to pre-establish LSP when mobile nodes move to the coverage edge and detect the radio signal from new foreign agent (FA). When the MN determines to do a handover task to a new FA, it will reduce the time for movement detection, MN registration, and LSP establishment latency. The simulation results indicate that our proposed PEFRR can shorten end-to-end delay, and keep constant throughput.
