Abstract:
1. A system for a sample-analysis of data comprising a multitude of data packets, the system comprising: an input of a monitoring system receiving from a network data from which a parent population number (N) of data packets is provided, a sampling device the monitoring system setting a sample number (n), the sampling device sampling a sample group with the sample number (n) of data packets from the parent population number (N) of data packets, a classification device of the monitoring system classifying the sample group by classification rules into sample-flow-groups (f a computing device of the monitoring system determining sample-flow-mean-sizes (μ the computing device determining sample-flow-variances (v determining sample-flow-ratios (p the computing device calculating an estimated flow size (Sum the computing device calculating a variance (V[Sum and N M μ N denotes the parent population number (N), p n denotes the sample number (n), n x wherein the variance (V[Sum f ]) of the estimated flow size (Sum f ) is calculated by and V P
