It -accomplishes this by measuring the time spent transmitting to or -receiving from a station at TX and RX completion, and accounting this to -a per-station, per-QoS level airtime deficit. Then, an FQ-CoDel based -deficit scheduler is employed at packet dequeue time, to control which -station gets the next transmission opportunity. - -Airtime fairness can significantly improve the efficiency of the network -when station rates vary. The following throughput values are from a -simple three-station test scenario, where two stations operate at the -highest HT20 rate, and one station at the lowest, and the scheduler is -employed at the access point: - - Before / After -Fast station 1: 19.17 / 25.09 Mbps -Fast station 2: 19.83 / 25.21 Mbps -Slow station: 2.58 / 1.77 Mbps -Total: 41.58 / 52.07 Mbps - -The benefit of airtime fairness goes up the more stations are present. -In a 30-station test with one station artificially limited to 1 Mbps, -we have seen aggregate throughput go from 2.14 to 17.76 Mbps. - -Signed-off-by: Toke Høiland-Jørgensen <toke@toke.dk> -Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com> ---- - |
