queues). Your Device uses the Token Bucket algorithm to allow a certain amount
of large bursts while keeping a limit at the average rate.

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.
(Before Traffic Policing)
The 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 16.8 on page 210
