The work of task group e reflects the IEEE principle of avoiding the invention of new
standards when existing ones can be reused. This fact is evidenced in the parts of 802.11e
dedicated to priority queues and traffic classes. These concepts are the same ones used in
earlier IEEE and IETF standards related to QoS (see [9]). For instance, the 802.11e standard
uses the priority values 0 to 7, which are identical to the IEEE 802.1P priority tags. Task
group e uses the definition of Traffic Specification (TSPEC) for traffic classes identical to
