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 | |||

61 | Stab | ||
62 | |||
63 | Lookup table for log((1-W)^(t/t_ave). | ||

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 | ||
