Minimum Contention Window. This parameter is input to the algorithm that determines 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.。
CWmax：Maximum Contention Window. The value specified here in the Maximum Contention

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".。

Priority
Low High throughput. Bulk data that requires
maximum throughput and is not time-sensitive is
sent to this queue (FTP data, for example).
Medium Medium throughput and delay. Most traditional
IP data is sent to this queue.
High Minimum delay. Time-sensitive video data is
automatically sent to this queue.
High Time-sensitive data like VoIP and streaming
media are automatically sent to this queue.
