            Requirements for Distributed Mobility Management
                     draft-ietf-dmm-requirements-16

Abstract

   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.

Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119 [RFC2119].
