Mobility management with low latency time by using the GSMP on the MPLS network

Abstract

In this paper, we aim to reduce handover latency time. For this purpose, the proposed method takes advantage of current General Switch Management Protocol (GSMP) over Multi-Protocol Label Switching network, and presents a path change procedure. For removing triangular problem, the proposed method substitutes a controller in GSMP for the role of Home Agent in Mobile IP. Consequently, we can reduce the handover latency time because a controller in using GSMP knows the overall network configuration status without rerouting and long reporting time.
