| 10 | /* Random Early Detection (RED) algorithm. | ||
| 11 | ======================================= | ||
| 12 | |||
| 13 | Source: Sally Floyd and Van Jacobson, "Random Early Detection Gateways | ||
| 14 | for Congestion Avoidance", 1993, IEEE/ACM Transactions on Networking. | ||
| 15 | |||
| 16 | This file codes a "divisionless" version of RED algorithm | ||
| 17 | as written down in Fig.17 of the paper. | ||
| 18 | |||
| 19 | Short description. | ||
| 20 | ------------------ | ||
| 21 | |||
| 22 | When a new packet arrives we calculate the average queue length: | ||
| 23 | |||
| 24 | avg = (1-W)*avg + W*current_queue_len, | ||
| 25 | |||
| 26 | W is the filter time constant (chosen as 2^(-Wlog)), it controls | ||
| 27 | the inertia of the algorithm. To allow larger bursts, W should be | ||
| 28 | decreased. | ||
| 29 | |||
| 30 | if (avg > th_max) -> packet marked (dropped). | ||
| 31 | if (avg < th_min) -> packet passes. | ||
| 32 | if (th_min < avg < th_max) we calculate probability: | ||
| 33 | |||
| 34 | Pb = max_P * (avg - th_min)/(th_max-th_min) | ||
| 35 | |||
| 36 | and mark (drop) packet with this probability. | ||
| 37 | Pb changes from 0 (at avg==th_min) to max_P (avg==th_max). | ||
| 38 | max_P should be small (not 1), usually 0.01..0.02 is good value. | ||
| 39 | |||
| 40 | max_P is chosen as a number, so that max_P/(th_max-th_min) | ||
| 41 | is a negative power of two in order arithmetics to contain | ||
| 42 | only shifts. | ||
| 43 | |||
| 44 | |||
| 45 | Parameters, settable by user: | ||
| 46 | ----------------------------- | ||
| 47 | |||
| 48 | qth_min - bytes (should be < qth_max/2) | ||
| 49 | qth_max - bytes (should be at least 2*qth_min and less limit) | ||
| 50 | Wlog - bits (<32) log(1/W). | ||
| 51 | Plog - bits (<32) | ||
| 52 | |||
| 53 | Plog is related to max_P by formula: | ||
| 54 | |||
| 55 | max_P = (qth_max-qth_min)/2^Plog; | ||
| 56 | |||
| 57 | F.e. if qth_max=128K and qth_min=32K, then Plog=22 | ||
| 58 | corresponds to max_P=0.02 | ||
| 59 | |||
| 60 | Scell_log | ||
| 61 | Stab | ||
| 62 | |||
| 63 | Lookup table for log((1-W)^(t/t_ave). | ||
| 64 | |||
| 65 | |||
| 66 | NOTES: | ||
| 67 | |||
| 68 | Upper bound on W. | ||
| 69 | ----------------- | ||
| 70 | |||
| 71 | If you want to allow bursts of L packets of size S, | ||
| 72 | you should choose W: | ||
| 73 | |||
| 74 | L + 1 - th_min/S < (1-(1-W)^L)/W | ||
| 75 | |||
| 76 | th_min/S = 32 th_min/S = 4 | ||
| 77 | |||
| 78 | log(W) L | ||
