WG103 ProSafe 802.11g Wireless Access Point Reference Manual • Station EDCA Parameters. Specify the Station EDCA parameters for different types of data transmitted from the wireless client to the wireless access point. If WMM is disabled, you cannot configure Station EDCA parameters (see "Configure Basic QoS Settings" on page 2-11). 4. Click Apply to save your settings. Table 5-1. QoS Queues and Settings QoS Queue Data 0 (Best Effort) Data 1 (Background) Data 2 (Video) Data 3 (Voice) AIFS (Arbitration Inter-Frame Space) cwMin (Minimum Contention Window) cwMax (Maximum Contention Window) Max. Burst Length (AP EDCA parameters only) TXOP Limit (Station EDCA parameters only) Description 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). Medium priority queue, medium throughput and delay. Most traditional IP data is sent to this queue. High priority queue, minimum delay. Time-sensitive video data is automatically sent to this queue. High priority queue, minimum delay. Time-sensitive data such as VoIP and streaming media are automatically sent to this queue. Specifies a wait time (in milliseconds) for data frames. Valid values for AIFS are 1 through 255. Upper limit (in milliseconds) of a range from which the initial random backoff wait time is determined. 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. Upper limit (in milliseconds) for the doubling of the random backoff value. 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. 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. Valid values for maximum burst length are 0.0 through 999.9. Specifies in milliseconds the Transmission Opportunity (TXOP) for a client station to initiate transmissions on the wireless medium (WM). Decreasing this value increases the priority of the queue. Valid values for the maximum TXOP limit are 0.0 through 999.9. 5-8 Advanced Configuration v1.0, February 2009

Station EDCA Parameters.
Specify the Station EDCA parameters for different types of
data transmitted from the wireless client to the wireless access point. If WMM is disabled,
you cannot configure Station EDCA parameters (see
“Configure Basic QoS Settings” on
page 2-11
).

Table 5-1. QoS Queues and Settings
QoS Queue
Description
Data 0 (Best Effort)
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).
Data 1 (Background)
Medium priority queue, medium throughput and delay. Most traditional
IP data is sent to this queue.
Data 2 (Video)
High priority queue, minimum delay. Time-sensitive video data is
automatically sent to this queue.
Data 3 (Voice)
High priority queue, minimum delay. Time-sensitive data such as VoIP
and streaming media are automatically sent to this queue.
AIFS (Arbitration Inter-Frame
Space)
Specifies a wait time (in milliseconds) for data frames. Valid values for
AIFS are 1 through 255.
cwMin (Minimum Contention
Window)
Upper limit (in milliseconds) of a range from which the initial random
backoff wait time is determined. 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.
cwMax (Maximum Contention
Window)
Upper limit (in milliseconds) for the doubling of the random backoff
value. 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.
Max. Burst Length
(AP EDCA parameters only)
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. Valid values
for maximum burst length are 0.0 through 999.9.
TXOP Limit
(Station EDCA parameters only)
Specifies in milliseconds the Transmission Opportunity (TXOP) for a
client station to initiate transmissions on the wireless medium (WM).
Decreasing this value increases the priority of the queue. Valid values
for the maximum TXOP limit are 0.0 through 999.9.
