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 GPON Device 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 146 for more
information on each metering algorithm.
