Funding Information:
Traffic visibility, and specifically measurements and monitoring in IP networks has become a very difficult task due to the overwhelming amounts of traffic and flows. One of the earliest network measurements tools was Cisco Netflow [1], which allowed IP flow level measurement. Netflow provided a variety of monitoring capabilities yet suffered from high processing and collection overheads, which were partially decreased using sampling in the variant Sampled Netflow, yet this variant provided reduced accuracy caused This research was supported by European Research Council (ERC) Starting Grant no. 259085, and the Neptune Consortium, administered by the Office of the Chief Scientist of the Israeli ministry of Industry, Trade, and Labor, and the Ministry of Science and Technology, Israel.
