Enumerate about the Traffic policing
Traffic policing happens when a flow of data is regulated so that cells (or frames or packets) that exceed a performance level are discarded or tagged. It might be desirable to supplement a traffic-policing policy with a traffic-shaping policy. Traffic shaping is used to smooth out a traffic flow and decrease cell clumping. This can result in a fairer allocation of resources and a decreased average delay time.
