Abstract :
Using ns-2 simulations, this paper evaluates an adaptive explicit congestion notification (AECN) router. By receiving round-trip time (RTT) source hints from each TCP flow, AECN divides flows into flow groups based on RTT ranges. AECN uses distinct flow group drop probabilities and a mark front scheme to provide higher goodput and better fairness than random early detection (RED) and explicit congestion notification (ECN) routers.
