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 ZyXEL 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 170 for more information on each metering
algorithm.
