The invention relates to a system and non-intrusive method for measuring loss rates and transfer durations for data flows that are sent by a telecommunication network in packet mode. The inventive method is characterized in that it comprises the following steps: classification of the data packet in a homogeneous flow; calculation of an identification signature for each data packet; counting of the packets in the flow; measurement of unidirectional transfer times per flow or information flow group and measurement of the loss rate for said packets.
L'invention concerne un système et un procédé non-intrusif de mesure des taux de perte et des durées de transfert des flux de données acheminés via un réseau de télécommunication en mode paquet. Le procédé selon l'invention est caractérisé en ce qu'il comporte les étapes suivantes: classification des paquets de données dans un flux homogène; calcul d'une signature d'identification de chaque paquet de données; comptage des paquets dans le flux; mesure, d'une part, des délais de transfert unidirectionnels par flux ou groupe de flux d'information et, d'autre part, du taux de perte de paquets.
