Active Queue Management (AQM) can potentially reduce packet drop rate in the Internet. This is used by routers to control congestion, where packets are dropped before queue become full. In order to improve the performance of congestion routers, a new framework of AQM, namely NEWQUE active queue management algorithm supporting Explicit Congestion Notification (ECN), is proposed. The objective of the new algorithm is to improve performance of congested routers by keeping low queuing delay, packet drop rate low, link utilization high, and link utilization stable. The NEWQUE AQM is implemented with help of ns2 simulator. The simulation shows that the proposed design outperforms the peer AQM schemes in terms of packet loss, link utilization and queuing delay.
