Abstract

   As internet traffic is increasingly sourced-from and destined-to
   wireless endpoints, it is crucial that Quality of Service be aligned
   between wired and wireless networks; however, this is not always the
   case by default.  This document specifies a set Differentiated
   Services Code Point (DSCP) to IEEE 802.11 User Priority (UP) mappings
   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.
