Overview of fuzzy-RED in diff-serv networks

Abstract

The rapid growth of the Internet and increased demand to use theInternet for time-sensitive voice and video applications necessitate the designand utilization of new Internet architectures with effective congestion controlalgorithms. As a result the Diff-Serv architectures was proposed to deliver(aggregated) QoS in TCP/IP networks. Network congestion control remains acritical and high priority issue, even for the present Internet architecture. In thispaper we present Fuzzy-RED, a novel approach to Diff-Serv congestioncontrol, and compare it with a classical RIO implementation. We believe thatwith the support of fuzzy logic, we are able to achieve better differentiation forpacket discarding behaviors for individual flows, and so provide better qualityof service to different kinds of traffic, such as TCP/FTP traffic and TCP/Webliketraffic, whilst maintaining high utilization (goodput). © Springer-Verlag Berlin Heidelberg 2002.
