Service Differentiation in ECN Networks Using Weighted Window-Based Congestion Control for Various Packet Marking Algorithms

Abstract

We investigate the service differentiation, in terms of average throughput, and the performance achieved using weighted window-based congestion control in networks supporting Explicit Congestion Notification (ECN). Our results show how service differentiation, queueing delay, and average throughput are affected by the increase and decrease rules of the end-system congestion control algorithms, and how they depend on the marking algorithms operating in the routers. The end-system algorithms we investigate include algorithms that achieve an average hroughput proportional to some willingness-to-pay, and the marking algorithms include RED, virtual queue marking, and load-based marking.KeywordsQueue LengthTransmission Control ProtocolCongestion ControlRound Trip TimeAverage ThroughputThese keywords were added by machine and not by the authors.
