We divide the experimental evaluation into two parts. The first group of experiments evaluates the efficacy of the core flow slicing algorithm and the multi-factor smart sampling algorithm. The second group compares the Flow Slices solution with Adaptive NetFlow (ANF) to show the efficacy of Flow Slices both in terms of memory usage and accuracy of estimates. For our evaluations, we obtained traces on an OC-48 link from CAIDA [4].
