        Diameter Support for Proxy Mobile IPv6 Localized Routing
                      draft-ietf-dime-pmip6-lr-16

Abstract

   In Proxy Mobile IPv6, packets received from a Mobile Node (MN) by the
   Mobile Access Gateway (MAG) to which it is attached are typically
   tunneled to a Local Mobility Anchor (LMA) for routing.  The term
   "localized routing" refers to a method by which packets are routed
   directly between an MN's MAG and the MAG of its Correspondent Node
   (CN) without involving any LMA.  In a Proxy Mobile IPv6 deployment,
   it may be desirable to control the establishment of localized routing
   sessions between two MAGs in a Proxy Mobile IPv6 domain by requiring
   that the session be authorized.  This document specifies how to
   accomplish this using the Diameter protocol.

1.  Introduction

   Proxy Mobile IPv6 (PMIPv6) [RFC5213] allows the Mobility Access
   Gateway (MAG) to optimize media delivery by locally routing packets
   from a Mobile Node to a Correspondent Node that is locally attached
   to an access link connected to the same Mobile Access Gateway,
   avoiding tunneling them to the Mobile Node's Local Mobility Anchor
   (LMA).  This is referred to as "local routing" in RFC 5213.  However,
