Experimental study of RED Performance by regulating Upper Threshold Parameter

achieve high throughput and low average delay by stabilizing the average queue size by mapping the congestion level into packet drop probability [PDP]. Random Early Detection [RED] is widely used AQM mechanism for detection and avoidance of incipient congestion, but it is very sensitive to its parameter setting that can degrade network performance. This paper describes a new enhanced mechanism to reduce parameter sensitivity and to improve the network performance in a congested network. This mechanism has been tested in different network scenarios to test its validity and results shows that proposed mechanism have improved packet delivery ratio and throughput in a congested network. 1
