This paper concerns the problem of estimating the Internet flow duration distribution from indirect measurements due to network constraints. The aim is to estimate the distribution from observing: the possible superpositions (collisions) of sampled flow durations, the flow arrivals-to-departures times without identification of sampled flows and the number of sampled flows in progress. For each type...
We introduce a new method of data collection for flow size estimation, the optimized flow sampling sketch, which combines the optimal properties of flow sampling with the computational advantages of a counter array sketch. Using Fisher information as a definitive basis of comparison, we show that the statistical efficiency of the method is within a constant factor of that of flow sampling, which is...
