Abstract :
Random early detection (RED) has been proposed to avoid impending Internet congestion and simultaneously achieve high throughput and low average delay. However, it has been found that the interaction between a RED gateway and TCP connections may exhibit complicated nonlinear (in particular, chaotic) behavior and lead to network instability. In this paper a time-delayed state feedback controller is implemented to enhance the stability of RED. We validate the algorithm by extensive ns-2 simulations.
