Traffic Priority

The switch provides Quality of Service (QoS) by prioritizing each packet
based on the required level of service, using two distinct categories with
Weighted Fair Queuing. It uses IEEE 802.1Q and 802.1p tags to prioritize
incomming traffic based on input from the end-station application
driver. These functions can be used, for example, to provide
independent priorities for real-time video, real-time voice, guaranteed-
delivery data, or best-effort data.
