  1. Design and Evaluation:Approximate Fair & Control DelayQueue Management Schemes over High Speed Networks Lin Xue 2012.12

  2. 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

  3. 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

  4. Fair Target of the Flow Fair target = flow’s share ^ -3 Fair target Flow’s share

  5. FIFO Result (1 CUBIC & 1 RENO) Cwnd RTT

  6. AF-CODEL Result (1 CUBIC & 1 RENO) Cwnd RTT

  7. 1 CUBIC, 1 HSTCP, 1 RENO (RTT=120ms) Fairness Delay

  8. 10 CUBIC, 10 HSTCP, 10 RENO (RTT=120ms) Fairness Delay

  9. 10 CUBIC, 10 HSTCP, 10 RENO (RTT=60ms) Fairness Delay

  10. 10 CUBIC, 10 HSTCP, 10 RENO with background traffic (RTT=120ms) Fairness Delay
