Traffic Policing
Traffic policing is the limiting of the input or output transmission rate of a class of traffic on the basis of
user-defined criteria. Traffic policing methods measure traffic flows against user-defined criteria and
identify it as either conforming, exceeding or violating the criteria.

The VMG supports three incoming traffic metering algorithms: Token Bucket Filter (TBF), Single Rate Two
Color Maker (srTCM), and Two Rate Two Color Marker (trTCM). You can specify actions which are
performed on the colored packets. See Section 10.8 on page 158 for more information on each
metering algorithm.
