This shows the traffic metering algorithm used in this policer.
The Simple Token Bucket algorithm uses tokens in a bucket to control when traffic can be
transmitted. Each token represents one byte. The algorithm allows bursts of up to b bytes
which is also the bucket size.
The Single Rate Three Color Marker (srTCM) is based on the token bucket filter and
identifies packets by comparing them to the Committed Information Rate (CIR), the
Committed Burst Size (CBS) and the Excess Burst Size (EBS).
The Two Rate Three Color Marker (trTCM) is based on the token bucket filter and
identifies packets by comparing them to the Committed Information Rate (CIR) and the
Peak Information Rate (PIR).
