In this demo we will demonstrate the possibility of using OpenFlow traffic measurements for link dimensioning purposes. Our solution runs on top of the Ryu OpenFlow controller and retrieves per-flow statistics metered at the OpenFlow switch. The statistics are obtained by using messages defined by the OpenFlow protocol. These statistics are then applied to a flow-based link dimensioning approach, originally proposed to operate with NetFlow input. By demonstrating our solution in a testbed, we are able to compare the OpenFlow-based approach with a NetFlow-based one and with the actual traffic demands calculated directly from the packet traces. With that, we show how quality of OpenFlow measurements affects the link dimensioning and how feasible their use in such applications is.
