             Guidelines for DiffServ to IEEE 802.11 Mapping
                    draft-ietf-tsvwg-ieee-802-11-00

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 is due to the fact that two independent
   standards bodies provide QoS guidance on wired and wireless networks:
   specifically, the IETF specifies standards and design recommendations
   for wired IP networks, while a separate and autonomous standards-
   body, the IEEE, administers the standards for wireless 802.11
   networks.  The purpose of this document is to propose a set
   Differentiated Services Code Point (DSCP) to IEEE 802.11 User
   Priority (UP) mappings to reconcile the marking recommendations
   offered by these two standards bodies, and, as such, to optimize
   wired-and-wireless interconnect QoS.
