            Quality of Service Option for Proxy Mobile IPv6
                   draft-ietf-netext-pmip6-qos-01.txt

Abstract

   This specification defines a new mobility option that can be used by
   the mobility entities in the Proxy Mobile IPv6 domain to exchange
   Quality of Service parameters associated with a subscriber's IP
   flows.  Using the QoS option, the local mobility anchor and the
   mobile access gateway can exchange available QoS attributes and
   associated values.  This enables QoS policing and labeling of packets
   to enforce QoS differentiation on the path between the local mobility
   anchor and the mobile access gateway.  Furthermore, making QoS
   parameters available on the MAG enables mapping these parameters to
   QoS rules being specific to the access technology which operates
   below the mobile access gateway.  After such mapping, QoS rules can
   be enforced on the access technology components, such as an IEEE
   802.11e Wireless LAN controller.
