ProSAFE Wireless Controller Manage Quality of Service for an Advanced Profile Group Quality of Service (QoS) management lets you fine-tune priorities for different types of traffic. Quality of Service Concepts Quality of Service (QoS) works by default for the advanced profile groups. Change QoS only if a specific reason exists, such as when specifications of a device vendor require you to use different QoS settings. Using QoS Wi-Fi MultiMedia (WMM) ensures that the applications that require better throughput and performance are provided special queues with higher priority. For example, video and audio applications are given higher priority over applications such as FTP. WMM defines the following four queues in decreasing order of priority: • Voice. The highest priority queue with minimum delay, which makes it ideal for applications such as voice over IP (VoIP) and streaming media. • Video. The second highest priority queue with low delay is given to this queue. Video applications are routed to this queue. • Best Effort. The medium priority queue with medium delay is given to this queue. Most standard IP applications use this queue. • Background. Low priority queue with high throughput. Applications, such as FTP, that are not time-sensitive but require high throughput can use this queue. QoS prioritization and coordination of WiFi medium access is enabled automatically. QoS settings on the access point control downstream traffic that flows from the access point to the client station (AP Enhanced Distributed Channel Access [EDCA] parameters) and the upstream traffic that flows from the client station to the access point (Station EDCA parameters). The Advanced QoS Settings page lets you change the QoS settings per profile group and per radio for upstream traffic flowing from the station (that is, the WiFi client) to managed access points and the downstream traffic flowing from managed access points to the station. These settings are applied only to managed access points that are capable of supporting these settings. Disabling WMM deactivates QoS control of station EDCA parameters for upstream traffic flowing from the client station to the access point. (You can change the settings for the station EDCA parameters, but these settings do not take effect until you enable WMM.) However, when WMM is disabled, you can still set some parameters for downstream traffic flowing from the access point to the client station (AP EDCA parameters), and these settings do take effect even when WMM is disabled.
