transmission of packets in each queue based on the requirements of the media being sent. Queues
automatically provide minimum transmission delay for Voice, Video, multimedia, and mission
critical applications, and rely on best-effort parameters for traditional IP data

CWmin CWmin
CWmin: Minimum Contention Window. This parameter is input to the algorithm that determines CWmin
the initial random backoff wait time ("window") for retry of a transmission. The value specified
here in the Minimum Contention Window is the upper limit (in milliseconds) of a range from
which the initial random backoff wait time is determined.
The first random number generated will be a number between 0 and the number specified here.
If the first random backoff wait time expires before the data frame is sent, a retry counter is
incremented and the random backoff value (window) is doubled. Doubling will continue until the
size of the random backoff value reaches the number defined in the Maximum Contention
Window. Valid values for the "cwmin" are 1, 3, 7, 15, 31, 63, 127, 255, 511, or 1024. The value for
"cwmin" must be lower than the value for "CWmax".
Cmax Cmax
Cmax：Maximum Contention Window. The value specified here in the Maximum Contention Cmax
Window is the upper limit (in milliseconds) for the doubling of the random backoff value. This
doubling continues until either the data frame is sent or the Maximum Contention Window size is
reached. Once the Maximum Contention Window size is reached, retries will continue until a
maximum number of retries allowed is reached. Valid values for the "cwmax" are 1, 3, 7, 15, 31,
63, 127, 255, 511, or 1024. The value for "cwmax" must be higher than the value for "CWmin".

AIFSN AIFSN：The Arbitration Inter-Frame Spacing Number specifies a wait time (in milliseconds) for
data frames.
