AF&CODEL queue mechanism: Enqueue Packet enqueue Sample packet (sample interval 1/500 packets) Y N Update shadow buffer(SB, size 2000) and flow table (FT, size 100) Enqueue
AF&CODEL queue mechanism: Dequeue Packet dequeue Within interval(100ms) Min Queuing delay > Fair_targetof the flow N Y Drop Stop drop Dequeue next packet Schedule next drop
Fair Target of the Flow Fair target = flow’s share ^ -3 Fair target Flow’s share
