Abstract
A method of detecting anomalies in a communication system, includes: providing a first packet flow portion and a second packet flow portion; extracting samples of a numerical feature associated with a traffic status of the first and second packet flow portions; computing from said extracted samples a first statistical dispersion quantity and a second statistical dispersion quantity of the numerical feature associated with the first and second packet flow portions, respectively; computing from the dispersion quantities a variation quantity representing a dispersion change from the first packet flow portion to the second packet flow portion; comparing the variation quantity with a comparison value; and detecting an anomaly in the system in response to said comparison.
