Drag & Drop
cloud-based weighted fair queueing

policing
shaping
categorizes packets based on the value of a traffic descriptor
guarantees minimum bandwidth to specific traffic classes when an interface is congested
prevents congestion by reducing the flow of outbound traffic
outcome of overutilization
uses defined criteria to limit the transmission of one or more classes of traffic
Explanation

QoS classification identifies traffic by matching packet descriptors such as markings or header fields. CBWFQ guarantees minimum bandwidth for configured classes when a link is congested. Shaping reduces and smooths outbound traffic to help prevent congestion, typically by buffering excess packets. Congestion is the result of overutilized network resources. Policing limits traffic that exceeds a defined rate or class policy, usually by dropping or remarking packets.
