The present invention provides a traffic analyzing system on a communications link having analyzer circuits connected to each other by a number of links, where each analyzer circuit has a data rate lower than the data rate of the communications link, and are adapted to perform respective different levels of analysis on packets. The information extracted from the packets analyzed at a first level of analysis by a first analyzer circuit is forwarded to a second level of analysis performed at a second analyzer circuit, where the additional analysis performed by the second analyzer circuit depends on the analysis performed by the first analyzer circuit. Such a system and associated method allows for an efficient, practical, and improved traffic flow analyses for computer networks to evaluate high-speed and heavy traffic flow, as well as for improved protocol analysis for emerging technologies.

Système d'analyse de trafic sur liaison de communications à circuits d'analyse reliées entre eux par différentes liaisons, chaque circuit ayant un débit binaire inférieur à celui de la liaison de communications, et capable d'assurer différents niveaux d'analyse sur les paquets. L'information extraite des paquets analysés à un premier niveau par un premier circuit d'analyse est ransmise à un second niveau d'analyse conduit par une second circuit d'analyse, et l'autre analyse effectuée par le second circuit dépend de celle effectuée par le premier. Le système décrit et le procédé connexe assurent des analyses de flux de trafic efficaces, pratiques et améliorées pour les réseaux informatiques, permettant une évaluation de flux haute vitesse et fort trafics, et une analyse de protocole améliorée pour les technologies émergentes..
