Abstract
Methods and apparatus are provided for applying color based policing at a network node. Committed information rate (CIR) and peak information rate (PIR) buckets used to monitor transmission rates are augmented using CIR overflow and PIR overflow buckets. The CIR and PIR overflow buckets hold tokens provided to CIR and PIR buckets that exceed the associated burst limits. Based on the availability of tokens and the color associated with a received packet, an action can be applied to the packet that promotes the color associated with the packet.
