5.5.1
AP EDCA Parameters
AP Enhanced Distributed Channel Access (EDCA) parameters affect traffic flowing from the EAP
device to the client station.
Figure 5-30 AP EDCA Parameters
Queue:
Queue displays the transmission queue. By default, the priority from high to
low is Data 0, Data 1, Data 2, and Data 3. The priority may be changed if you
reset the EDCA parameters.
Data 0 (Voice)
—
Highest priority queue, minimum delay. Time-sensitive
data such as VoIP and streaming media are automatically sent to this queue.
Data 1 (Video)
—
High priority queue, minimum delay. Time-sensitive video
data is automatically sent to this queue.
Data 2 (Best Effort)
—
Medium priority queue, medium throughput and
delay. Most traditional IP data is sent to this queue.
Data 3 (Background)
—
Lowest priority queue, high throughput. Bulk data
that requires maximum throughput and is not time-sensitive is sent to this
queue (FTP data, for example).
Arbitration Inter-
Frame Space:
A wait time for data frames. The wait time is measured in slots. Valid values
for
Arbitration Inter-Frame Space
are from 1 to 15.
Minimum
Contention
Window:
A list to the algorithm that determines the initial random backoff wait time
(window) for retry of a transmission.
This value can not be higher than the value for the
Maximum Contention
Window
.
Maximum
Contention
Window:
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.
This value must be higher than the value for the
Minimum Contention
Window.
Maximum Burst
The
Maximum Burst
is a AP EDCA parameter that applies only to traffic
flowing from the EAP devices to the client station. This value specifies (in
milliseconds) the maximum burst length allowed for packet bursts on the
wireless network. A packet burst is a collection of multiple frames
transmitted without header information. The decreased overhead results in
higher throughput and better performance.
The valid values are multiples of 32 between 0 and 8192.
