On the Statistics of QoS Parameters over Heterogeneous Networks⋆

چکیده
Offering real services with a specific Quality of Service (QoS) guarantee over heterogeneous networks is very challenging. To make it feasible a complete and robust real performance assessment of these scenarios is of paramount importance. This paper deals with a performance evaluation and measurement of a number of heterogeneous endto-end (e2e) paths taking into account a wide range of statistics. An active measurement approach of UDP QoS parameters has been adopted for the studying of (i) proprieties we called concise statistics (mean, standard deviation, inter quantile range, minimum, maximum, and median) and (ii) detailed statistics (Probability Density Function, Auto Correlation Function, Entropy, and log-log Complementary Cumulative Distribution Function). Used tools and traces are publicly available at www.grid.unina.it/Traffic/.
