A new AQM algorithm for enhancing internet capability against unresponsive flows

Abstract

The unresponsive flows to the network congestion control are dangerous to the equilibrium and the Quality-of-Service (QoS) of the whole Internet. In this paper, a new network queue management algorithm- CCU (Compare and Control Unresponsive flows) is proposed in order to strengthen the robustness of Internet against unresponsive flows. As a sort of active queue management (AQM) algorithm, CCU relies on the detection and punishment of unresponsive flow and gets the elastics control of unresponsive flows, which benefit the buffer queue with the high performance. Via the comparison and evaluation experiments, it has been proved that CCU can detect and restrain unresponsive flows more accurately compared to other AQM algorithms. © Springer-Verlag Berlin Heidelberg 2005.
