A Realization of mobile All-IP networks calls not only for seamless handover protocols, but also fast processing, especially for real-time IP traffic flows. In this paper, we propose to exploit pre-established label switched paths with the aim to reduce handover processing latency which is one of the most critical performance metrics in micro-mobility environment. Thus, our proposed scheme has an advantage of offering micro-mobility to Mobile IP (MIP) with lower-latency handover as compared with the several existing MPLS-based MIP approaches. A detailed analytic model of setting up LSPs for fast handover processing is presented. Further, we do not only investigate the performance of our model but also propose detailed signaling steps so that our proposed scheme could be run on MPLS-based MIP system.
