Traffic measurements are increasingly sampled due to ever growing line rates and concomitant traffic volumes. On the other hand, measurement-based applications increasingly depend on fine grained traffic characterization. Can these applications work effectively with existing sampled measurements? And if not, can we better match sampling techniques to applications? This talk describes the challenges and limitations for using sampled traffic measurements, and some recent approaches that move beyond traffic sampling methods in predominant use today.
