WMM (Wi-Fi Multimedia) – Enabled on individual WLAN Services, is a
standard that provides multimedia enhancements that improve the user
experience for audio, video, and voice applications. WMM is part of the
802.11e standard for QoS.
IP ToS (Type of Service) or DSCP (Diffserv Codepoint) – The ToS/DSCP
field in the IP header of a frame is used to indicate the priority and Quality of
Service for each frame. The IP TOS and/or DSCP is maintained within CTP
(CAPWAP Tunneling Protocol) by copying the user IP QoS information to the
CTP header—this is referred to as Adaptive QoS.
6.9.4.2 Defining the service class
Service class is determined by the combination of the following operations:
The class of treatment given to a packet. For example, queuing or per hop
behavior (PHB).
The packet marking of the output packets (user traffic and/or transport).
Table 23 Service classes
The service class is equivalent to the 802.1D UP (user priority).
