    Proxy Mobile IPv6 extensions for Distributed Mobility Management
                   draft-bernardos-dmm-pmipv6-dlif-00

Abstract

   Distributed Mobility Management solutions allow for setting up
   networks so that traffic is distributed in an optimal way and does
   not rely on centralized deployed anchors to provide IP mobility
   support.

   There are many different approaches to address Distributed Mobility
   Management, as for example extending network-based mobility protocols
   (like Proxy Mobile IPv6), or client-based mobility protocols (as
   Mobile IPv6), among others.  This document follows the former
   approach, and proposes a solution based on Proxy Mobile IPv6 in which
   mobility sessions are anchored at the last IP hop router (called
   mobility anchor and access router).  The mobility anchor and access
   router is an enhanced access router which is also able to operate as
   local mobility anchor or mobility access gateway, on a per prefix
   basis.  The document focuses on the required extensions to
   effectively support simultaneously anchoring several flows at
   different distributed gateways.

   This document introduces the concept of distributed logical
   interface, which is a software construct that allows to easily hide
   the change of anchor from the mobile node.
