WrrClassifier

simple module

This module implements weighted round-robin classifier.

There is a weight associated with each output gate. Initially each output gate gets as many tokens as their weight. When a packet is pushed then the first output gate is selected that has a packet and enough tokens, and one token is consumed. When there is not enough tokens to classify a packet, then each token bucket is filled up.

Extends

Name	Type	Description
PacketClassifierBase	simple module	This is a base module for various packet classifier modules. Derived modules must implement a single packet classifier function which determines the index of the output gate for the next pushed packet.

Parameters
