         Proxy Mobile IPv6 Extensions to Support Flow Mobility
                  draft-ietf-netext-pmipv6-flowmob-03

Abstract

   Proxy Mobile IPv6 allows a mobile node to connect to the same Proxy
   Mobile IPv6 domain through different interfaces.  However, the
   ability of movement of selected flows from one access technology to
   another is missing in the basic Proxy Mobile IPv6 protocol.  This
   document describes extensions to the Proxy Mobile IPv6 protocol that
   are required to support network based flow mobility over multiple
   physical interfaces.

   This document assumes that the mobile node implements the logical
   interface model, therefore allowing the support of traffic flows on
   different physical interfaces regardless of the assigned prefixes on
   these physical interfaces.

1.  Introduction

   Proxy Mobile IPv6 (PMIPv6), specified in [RFC5213], provides network
   based mobility management to hosts connecting to a PMIPv6 domain.
   PMIPv6 introduces two new functional entities, the Local Mobility
   Anchor (LMA) and the Mobile Access Gateway (MAG).  The MAG is the
   entity detecting Mobile Node's (MN) attachment and providing IP
