Active Queue Management Algorithm Based on Congestion Forecast Threshold

Lai Jun Ye Wu Feng Sui-li(School of Electronic and Information Engineering,South China University of Technology,Guangzhou 510640,Guangdong,China)  
In order to solve the problem of sharp decline in performance which exists in Drop Tail gateways and to find a novel algorithm that is easy to implement and can adapt parameters according to the variation of network,an active queue management(AQM) algorithm with explicit congestion notification(ECN) named bandwidth-delay product queue(BDPQ) is proposed.In this algorithm,the congestion in the buffer of the bottleneck gateway is monitored according to the current queue length,and the bandwidth-delay product is used as the threshold for congestion detection.If the queue length exceeds the threshold,the dequeuing packets will be marked according to the ECN policy to notify the congestion to the TCP source.Simulated results show that the proposed algorithm is of high link utilization,short mean queue,low loss rate and good fairness.
