Configuring QoS

Quality of Service (QoS) provides you with the ability to specify parameters on multiple queues for increased throughput and better performance of differentiated wireless traffic like Voice-over-IP (VoIP), other types of audio, video, and streaming media as well as traditional IP data over the D-Link Unified Access System.

For detailed information about QoS and how it is used in the D-Link Unified Access System, see Appendix D, “Understanding Quality of Service” on page 203.

Figure 72. QoS Configuration

Configuring Quality of Service (QoS) on the D-Link Unified Access System consists of setting parameters on existing queues for different types of wireless traffic, and effectively specifying minimum and maximum wait times (through Contention Windows) for transmission. The settings described here apply to data transmission behavior on the access point only, not to that of the client stations.

AP Enhanced Distributed Channel Access (EDCA) Parameters affect traffic flowing from the access point to the client station. Station Enhanced Distributed Channel Access (EDCA) Parameters affect traffic flowing from the client station to the access point.

NOTE:QoS is configured per radio interface.
