Self-Tuning Random Early Detection Algorithm to Improve Performance of Network Transmission

Algorithm 1

Self-tuning RED algorithm.

set 𝑤 by the inequality(3.12)

every 𝑞_ave update

 Sum = sum + 𝑞_ave;

 𝑛=𝑛+1;

 If now > 𝐿 time + δt

 𝑞^∼_ave = sum/n;

 update 𝑝_max by formula  (3.6)

 sum = 0;

 𝑛 = 0;

 𝐿 time = now;

Parameters:

now: current time

𝐿 time: the last time 𝑝_max was calculated

δt: sampling period

sum: the sum of 𝑞_ave in the period of δt

𝑛: the total number of 𝑞_ave sampled during δt
