 Chapter 10 Quality of Service (QoS)

VSG1432-B101 Series User’s Guide

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 

 for more information on each metering 

algorithm.
