Achieving the required QoS becomes the secret to a successful end-to-end business solution. Therefore,
QoS is the set of techniques to manage network resources.
QoS class
Every incoming frame is classified to a QoS class, which is used throughout the device for providing
queuing, scheduling and congestion control guarantees to the frame according to what was configured
for that specific QoS class. There is a one to one mapping between QoS class, queue and priority. A QoS
class of 0 (zero) has the lowest priority.
