Flow concurrency is the measure of the number of active flows at a given point in time at a given point in the network, and can be used as a complement to traffic volume to understand the dynamics of a measured network. It is of particular interest given the spread of devices through the network which keep per-flow state. In this paper, the authors first present a simple methodology for measuring flow concurrency using network flow data, then apply this methodology to a long-term data archive captured at the border of a national-scale research network to measure flow concurrency in selected example network configurations (e.g., at a content consumer network, on a content provider network, at an interconnect point).
