Keeping a small-size average queue size (which will in turn, offer a minimised delay performance) is regarded an important goal of Active Queue Management (AQM) algorithms implemented in internet routers. The long-established Random Early Detection (RED) algorithm is unable to achieve this desired objective. Herein, we present an enhanced RED algorithm, named Double Linear RED (DL-RED) which utilises a linear packet dropping function for light- and moderate- network traffic load scenarios and another linear packet dropping function for a heavy network traffic load scenario. The effectiveness of DL-RED was evaluated and compared with two other well-researched algorithms using the ns-3 simulation platform. Experimental results proved that DL-RED performed better than both prior algorithms with reference to delay and throughput. Importantly, a little effort is required to amend the packet dropping probability profile of RED's algorithm implementation with DL-RED.
