Monitoring ISP Networks Without DPI

Timo Klos and Stefan Meinders

In this presentation, we will review trends in Over-the-Top (OTT) traffic usage, user behavior and rapidly growing volumes of video streaming from services such as Netflix. The amount of video traffic carried by networks and its interconnections is significant. Delivery methods and encryption are challenges for today’s methods of network analysis—as are unexpected network changes that can drastically impact subscribers, transit costs, and network overload. Recent research unveiled that existing monitoring tools cannot cope with these variations in traffic delivery, caching strategies, and encryption. Finally, we describe how the use of “big data” techniques and multi-dimensional databases combined with global internet service mapping provides new insights into traffic delivery, consumption, and quality.
