A combined delay and throughput proportional scheduling scheme for differentiated services

Abstract--The proportional differentiation model is a newly introduced approach for differentiated services networks. This paper proposes and evaluates a scheduling mechanism for the combined control of delay and throughput metrics, according to the proportional differentiation model. The scheme is based on the well known Little's Law. A moving window averaging mechanism and an active queue management scheme are simultaneously, and respectively used to achieve control over the relative throughputs as well as the relative delays between classes. The scheme does away with measurement of the actual packet delays, and state information is minimized. Some feasibility bounds are presented, and a simulation study shows the effectiveness of this scheme.
