Impact of Arrival and Service Characteristics on the Packet Queueing Performance

Abstract: It is known that the performance of queueing mechanisms in computer network nodes deteriorates when traffic is strongly autocorrelated, or has the batch structure, or when the service time is of high variability. It is not obvious however, which of those three factors plays the dominant role in this deterioration. In this paper, using realistic traffic parameterizations with different system loads and buffer sizes, we are trying to determine, which of the three prevails in making queues longer and packet losses higher.
