Abstract
A network traffic monitoring process of a communications network including: receiving data packets from a software-defined networking (SDN) flow switch; processing header of the received packets to identify its subsets belonging to respective network flows; detecting large network flows by determining a corresponding cumulative amount of data contained in the received packets for each of the network flow until it reaches or exceeds a predetermined threshold amount of data; for each detected large network flow, sending flow identification data to the SDN flow switch to identify further packets of the large network flow and to stop sending them to the network traffic monitoring component; periodically receiving from the SDN flow switch and processing the corresponding counter data and corresponding timestamp data to generate temporal metrics of the large network flow; and processing the generated temporal metrics with a trained classifier to classify the large network flow.
