Abstract

   Most existing IP mobility solutions are derived from Mobile IP
   principles where a given mobility anchor maintains Mobile Nodes (MNs)
   binding up-to-date.  Data traffic is then encapsulated between the
   mobility anchor and the MN or its Access Router.  These approaches
   are usually implemented on a centralised architectures where both MN
   context and traffic encapsulation need to be processed at a central
   network entity, i.e. the mobility anchor.  However, one of the trend
   in mobile network evolution is to "flatten" mobility architecture by
   confining mobility support in the access network, e.g. at the access
   routers level, keeping the rest of the network unaware of the
   mobility events and their support.  This document discusses the
   deployment of legay Proxy Mobile IP approach in such a flat
   architecture.  The solution allows to dynamically distribute mobility
   functions among access routers for an optimal routing management.
   The goal is also to dynamically adapt the mobility support of the
   MN's needs by applying traffic redirection only to MNs' flows when an
   IP handover occurs.
