Description
Define whether or not admission control mandatory (ACM) is to be supported
on APs configured with this EDCA profile.
WMM is an extension to the Carrier Sense Multiple Access with Collision
Avoidance (CSMA/CA) protocol's Distributed Coordination Function (DCF).
The collision resolution algorithm responsible for traffic prioritization depends
on the following configurable parameters for each AC:
arbitrary inter-frame space number (AIFSN)
minimum and maximum contention window (CW) size
For each AC, the backoff time is the sum of the AIFSN and a random value
between 0 and the CW value. The AC with the lowest backoff time is granted
the opportunity to transmit (TXOP). Frames with the highest priority AC are
more likely to get TXOP as they tend to have the lowest backoff times (a result
of having smaller AIFSN and CW parameter values). The value of the CW
varies through time as the CW doubles after each collision up to the maximum
CW. The CW is reset to the minimum value after successful transmission.
In addition, you can configure the TXOP duration for each AC.
