A modification of RED called the Gentle RED (GRED) has been proposed by adding the Gentle parameter to the original implementation of RED. This parameter has been turned on by default in the NS2 simulator versions 2.1b and later; claiming that it helps in smoothing out traffic in routers and increases network performance. In this article we revisit this parameter and show, through simulation, that this parameter should be turned off in current simulations of RED using the NS2 simulator and it should be replaced by any adaptation parameter such as the Adaptive parameter in ARED.

This paper presents the Weighted Random Early Detection (WTRED) strategy for congestion handling ... more This paper presents the Weighted Random Early Detection (WTRED) strategy for congestion handling in TCP networks. WTRED provides an adjustable weight parameter to increase the sensitivity of the average queue size in RED gateways to the changes in the actual queue size. This modification, over the original RED proposal, helps gateways minimize the mismatch between average and actual queue sizes in router buffers. WTRED is compared with RED and FRED strategies using the NS-2 simulator. The results suggest that WTRED outperforms RED and FRED. Network performance has been measured using throughput, link utilization, packet loss and delay.
