Distributed IP mobility management from the perspective of the IETF: motivations, requirements, approaches, comparison, and challenges

摘要: The recent explosion of mobile Internet traffic is accelerating the evolution network architectures toward flat with all IP backhaul support. mobility support protocols are thus required to be adopted in such architectures. Accordingly, IETF Distributed Mobility Management (DMM) working group was recently chartered address architectural changes rapidly increasing usages. Unlike existing protocols, DMM being considered at aim distributing an optimal way while not relying on centrally deployed anchors. In this article, we first discuss motivations and requirements DMM. We then present two different possible approaches: host-based network-based approaches. Furthermore, comprehensive comparison results provided. Finally, challenges developments protocols.
