Quality of Service Option for Proxy Mobile IPv6
draft-ietf-netext-pmip6-qos-02.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.
