In the past decade, a fair number of network-layer mobility protocols have been standardized [RFC6275] [RFC5944] [RFC5380] [RFC6301] [RFC5213]. Although these protocols differ in terms of functions and associated message formats, they all employ a mobility anchor to allow a mobile node to remain reachable after it has moved to a different network. Among other tasks that the anchor point performs, the anchor point ensures connectivity by forwarding packets destined to, or sent from, the mobile node. It is a centrally deployed mobility anchor in the sense that the deployed architectures today have a small number of these anchors and the traffic of millions of mobile nodes in an operator network is typically managed by the same anchor. Such a mobility anchor may still have to reside in the subscriber's provider network even when the subscriber is roaming to

             Requirements for Distributed Mobility Management


   This document defines the requirements for Distributed Mobility    Management (DMM) at the network layer.  The hierarchical structure in    traditional wireless networks has led primarily to centrally deployed    mobility anchors.  As some wireless networks are evolving away from    the hierarchical structure, it can be useful to have a distributed    model for mobility management in which traffic does not need to    traverse centrally deployed mobility anchors far from the optimal    route.  The motivation and the problems addressed by each requirement    are also described.
