Previous studies of Internet traffic have shown that a very small percentage of flows consume most of the network bandwidth. It is important to understand the characteristics of such flows for traffic monitoring and modeling purposes. Several prior researchers have characterized such flows using different classification schemes: by size as elephant and mice; by duration as tortoise and dragonfly; and by burstiness as alpha and beta traffic. However, it is not clear how these different definitions of flows are related to each other. In this paper, using data recorded from two different operational networks, the authors study these "Heavy-hitter" flows in four different dimensions, namely size, duration, rate and burstiness, and examine how they are correlated.
