An Exponential Active Queue Management Method Based on Random Early Detection

Algorithm 3

RED_E technique detailed pseudocode.

(1)	Initialisation stage
(2)	For every arriving packet at a RED-Exponential router buffer
	Calculate the for this packet at the RED-Exponential router buffer
	Examine the queue status at a router buffer, is it empty or not
	if the queue at a RED-Exponential router buffer is empty then
	Compute , where
	Else
(3)	Determine a congestion status at the RED-Exponential router buffer
	if value is less than value then
	Calculate value for the arriving packet as follows:
	else if value is greater than or equal to value and less than value then
	Mark/Drop the arriving packet probabilistically regarding to value due to occurrence of congestion
	else
	Mark/Drop every arriving packet due to occurrence of heavy congestion
(4)	When the RED-Exponential router buffer becomes empty
