Name	Type	Description
DualRateThreeColorClassifier	simple module	This packet classifier module classifies packets using two token buckets. Each packet is classified depending on which token bucket is the first one that contains the required number of tokens for the packet.

// This packet classifier module classifies packets using two token buckets.
// Each packet is classified depending on which token bucket is the first one
// that contains the required number of tokens for the packet.
//
// The first token bucket is filled with tokens using the committed information
// rate. The maximum number of tokens is determined by the committed burst size.
// The second token bucket is filled with tokens using the excess information
// rate. The maximum number of tokens is determined by the excess burst size.
// Excess tokens from the first token bucket overflow into the second token bucket.
//
// By default, packets consume 1 token per byte.
