DM3: Distributed Mobility Management in MPLS-Based Access Networks

Abstract

Over the last few years, mobility management in the Internet has been one of the most active fields in communications. The recent increasing mobile traffic demand is having an important impact on the design of mobile networks and some limitations are arising from traditional network deployments. In order to deal with this new scenario, mobility management network architectures are being redesigned towards a more distributed operation. In this paper, we introduce DM3 (distributed mobility management MPLS), a fully distributed architecture designed to track efficiently the mobility of users in the current paradigm of evolving mobile IP networks. In DM3 architecture, several nodes are distributed in the MPLS-based access network and the mobile nodes are served by a close-bymobility anchor.With this operation, we reduce the routing and registration update costs, and provide a low handoff latency with a minimal packet loss rate. Analytical and experimental results are presented to justify the benefits of our proposed architecture.
