This MIB provides information about WLAN QoS configuration.

GLOSSARY

IEEE 802.11
Standard to encourage interoperability among
wireless networking equipment.

WMM
WMM is a wireless QoS protocol designed to preferentially
transmit packets with high priority, thus guaranteeing
better QoS services for voice and video applications in
a wireless network.

EDCA
Enhanced distributed channel access (EDCA) is a channel
contention mechanism designed by WMM to preferentially
transmit packets with high priority and allocate more
bandwidth to such packets.

AC
Access category (AC), is used for channel contention.
WMM defines four access categories; they are AC-VO (voice),
AC-VI (video), AC-BE (best-effort), and AC-BK (background)
in the descending order of priority.  When contending for a
channel, a high-priority AC preempts a low-priority AC.

CAC
Connection admission control (CAC) limits the number of
clients that are using high-priority ACs (AC-VO and AC-VI)
to guarantee sufficient bandwidth for existing high-priority
traffic.

U-APSD
Unscheduled automatic power-save delivery (U-APSD) is a new
power saving mechanism defined by WMM to enhance the power
saving capability of clients.

SVP
SpectraLink voice priority (SVP) is a voice priority protocol
designed by the Spectralink company to guarantee QoS for voice
traffic.
