Mapping Diffserv to IEEE 802.11
Abstract
As Internet traffic is increasingly sourced from and destined to
wireless endpoints, it is crucial that Quality of Service (QoS) be
aligned between wired and wireless networks; however, this is not
always the case by default. This document specifies a set of
mappings from Differentiated Services Code Point (DSCP) to IEEE
802.11 User Priority (UP) to reconcile the marking recommendations
offered by the IETF and the IEEE so as to maintain consistent QoS
treatment between wired and IEEE 802.11 wireless networks.
