Mapping Quality of Service (QoS) Procedures
of Proxy Mobile IPv6 (PMIPv6) and WLAN
Abstract
This document provides guidelines for achieving end-to-end Quality of
Service (QoS) in a Proxy Mobile IPv6 (PMIPv6) domain where the access
network is based on IEEE 802.11. RFC 7222 describes QoS negotiation
between a Mobile Access Gateway (MAG) and Local Mobility Anchor (LMA)
in a PMIPv6 mobility domain. The negotiated QoS parameters can be
used for QoS policing and marking of packets to enforce QoS
differentiation on the path between the MAG and LMA. IEEE 802.11 and
Wi-Fi Multimedia - Admission Control (WMM-AC) describe methods for
QoS negotiation between a Wi-Fi Station (MN in PMIPv6 terminology)
and an Access Point. This document provides a mapping between the
above two sets of QoS procedures and the associated QoS parameters.
This document is intended to be used as a companion document to RFC
7222 to enable implementation of end-to-end QoS.
