Abstract
We investigate the service differentiation, in terms of average throughput, and performance achieved using weighted window-based algorithms 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 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 throughput proportional to some willingness-to-pay, and the marking algorithms include RED, virtual queue marking, and load-based marking.
Keywords: service differentiation, window-based congestion control, packet marking
