Statistical summaries of traffic in IP networks are at the heart of network operation and are used to recover information on the traffic of arbitrary subpopulations of flows. It is therefore of great importance to collect the most accurate and informative summaries given the router's resource constraints. Cisco's sampled NetFlow, based on aggregating a sampled packet stream into flows, is the most widely deployed such system.
