An Adaptive Active Queue Management Algorithm-Self-Adaptive BLUE
|
Abstract:
As a classical Active Queue Management (AQM) algorithm, compared with RED (Random Early Detection), BLUE has many advantages. BLUE uses packet loss and link idle events to manage congestion. However, there are still some insufficiencies in parameter setting for BLUE. Especially when TCP connections changed dramatically will lead to queue overflow and underflow. Based on the study of BLUE, a novel self-adaptive BLUE is proposed. NS simulation results show that the algorithm can effectively stabilize the queue occupation independent of the number of active TCP connections and mitigate the queue overflow and underflow, it can improve link utilization and decrease packet loss rate at the same time.
