8 Configuring Advanced Settings Table 55. QoS Settings Field Max. Burst Length WMM Mode Queue AIFS (Inter-Frame Space) Description AP EDCA Parameter Only (The Max. Burst Length applies only to traffic flowing from the access point 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. Valid values for maximum burst length are 0 through 999. Wi-Fi MultiMedia (WMM) is enabled by default. With WMM enabled, QoS prioritization and coordination of wireless medium access is on. With WMM enabled, QoS settings on the D-Link Unified Access System control downstream traffic flowing from the access point to client station (AP EDCA parameters) and the upstream traffic flowing from the station to the access point (station EDCA parameters). Disabling WMM deactivates QoS control of station EDCA parameters on upstream traffic flowing from the station to the access point With WMM disabled, you can still set some parameters on the downstream traffic flowing from the access point to the client station (AP EDCA parameters). To disable WMM extensions, click Disabled. To enable WMM extensions, click Enabled. Queues are defined for different types of data transmitted from stationto-AP: 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) Highest 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). The Arbitration Inter-Frame Spacing (AIFS) specifies a wait time (in milliseconds) for data frames. Valid values for AIFS are 1 through 255. Configuring QoS 165
