For network monitoring, management and operations it is important to understand the nature of the network traffic flowing
at a point in the network. Torrent, the set of all flows on a network link and s-torrents, logical sets of flows of network traffic are very useful in this context. However detecting and measuring torrent and the constituent s-torrents automatically is a challenge. In this work we describe a novel method to detect and measure torrents. We show the usefulness of the method in obtaining a more effective and deeper insight into the network’s behavior and utilization.
