When applying [Quality of Service](/qos), it is possible to implement a [CBWFQ](/qos-cbwfq) in combination with [traffic shaping](/qos-traffic-shaping) to deliver a more effective bandwidth management.  

CBWFQ ensures fair bandwidth distribution among different traffic classes while shaping controls the traffic rate to prevent congestion. Shaping can be applied to traffic classes defined by CBWFQ. This means you can classify traffic using CBWFQ and then apply shaping to each class as needed.
