Both shaping and policing mechanisms are used in a network to control the rate at
which traffic is admitted into the network. Both mechanisms use classification, so
they can differentiate traffic. They also use metering to measure the rate of traffic
and compare it to the configured shaping or policing polic y.
The difference between shaping and policing can be described in terms of their
n Shaping meters the traffic rate and delays excessive traffic so that it stays
within the desired rate limit. With shaping, traffic bursts are smoothed out
producing a steadier flow of data. Reducing traffic bursts helps reduce
congestion in the core of...
