NETGEAR WG302v2 manual QoS Queues and Parameters, QoS Queue Description

NETGEAR ProSafe 802.11g Wireless Access Point WG302v2 Reference Manual

SpectraLink Voice Priority (SVP) is a QoS approach for Wi-Fi deployments. SVP is an open specification that is compliant with the IEEE 802.11b standard. SVP minimizes delay and prioritizes voice packets over data packets on the Wireless LAN, thus increasing the probability of better network performance.

•Modify AP EDCA Parameters. Specify the AP EDCA parameters for different types of data transmitted from the WG302v2 to the wireless client.

•Modify Station EDCA Parameters. Specify the Station EDCA parameters for different types of data transmitted from the wireless client to the WG302v2. If WMM is disabled, you cannot configure Station EDCA parameters.

Table 4-2describes the settings for QoS Queues.

Table 4-2 QoS Queues and Parameters

QoS Queue	Description
Data 0 (Voice)	High 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).
AIFS (Arbitration	Specifies a wait time (in milliseconds) for data frames. Valid values for AIFS are
Inter-Frame Space)	1 through 255.
cwMin (Minimum	Upper limit (in milliseconds) of a range from which the initial random backoff wait
Contention Window)	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	Upper limit (in milliseconds) for the doubling of the random backoff value. Valid
Contention Window)	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	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.
