Quality of Service Overview

QoS is all about managing the bandwidth in a manner that aligns the delivery characteristics of a given flow with the available port resources. In a QoS context, a flow is a stream of IP packets that are classified with the same class of service as it transits the interface. QoS manages bandwidth for each flow by taking advantage of its ability to:

These QoS abilities collectively make up a Class of Service (CoS). The remainder of this section will briefly describe CoS and its components.
