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.
