         Proxy Mobile IPv6 Extensions to Support Flow Mobility
                  draft-ietf-netext-pmipv6-flowmob-13

Abstract

   Proxy Mobile IPv6 allows a mobile node to connect to the same Proxy
   Mobile IPv6 domain through different interfaces.  This document
   describes extensions to the Proxy Mobile IPv6 protocol that are
   required to support network based flow mobility over multiple
   physical interfaces.

   The extensions described in this document consist of the operations
   performed by the local mobility anchor and the mobile access gateway
   to manage the prefixes assigned to the different interfaces of the
   mobile node, as well as how the forwarding policies are handled by
   the network to ensure consistent flow mobility management.

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].
