Traffic policing can propagates bursts. When the traffic rate reaches the configured maximum rate, excess traffic is
dropped (or remarked). The result is an output rate that appears as a saw-tooth with crests and troughs. In contrast to
policing, traffic shaping retains excess packets in a queue and then schedules the excess for later transmission over
increments of time. The result of traffic shaping is a smoothed packet output rate.
