The present invention relates to an arrangement comprising means for handling switching of data packets or flows of data packets in a communication system supporting communication of packet data to functional units or processing arrangements for performing operations on the data packets. It comprises core processing means (10) with classifying means (13) for classifying packets/packet flows and defining the processing flow sequences applicable for the packets/packet flows, distributing means (12;19;22) for distributing or switching the packets/packet flows to the appropriate functional units or processing arrangements according to the applicable flow sequence, indication providing means for indicating the current position of the respective packets/packet flows in the respective applicable processing flow sequence and means (11) for detecting or retrieving packet flow sequence information such that re-classification of already classified packets can be avoided.

La présente invention concerne un dispositif comprenant des moyens de gestion de commutation de paquets de données ou de flux de paquets de données dans un système de communication supportant la communication de données par paquets vers des unités fonctionnelles ou des dispositifs de traitement pour la mise en oeuvre d'opérations sur les paquets de données. Ledit dispositif comprend un moyen de traitement central (10) présentant un moyen de classification (13) permettant de classifier des paquets/flux de paquets et de définir les séquences de flux de traitement applicables pour les paquets/flux de paquets, des moyens de distribution (12 ;19 ; 22) permettant de distribuer ou de commuter les paquets/flux de paquets vers les unités fonctionnelles ou les dispositifs de traitement appropriés en fonction de la séquence de flux applicable, un moyen de fourniture d'indications permettant d'indiquer la position courante des paquets/flux de paquets respectifs dans la séquence de flux de traitement respective et un moyen (11) permettant de détecter ou de récupérer des informations de séquence de flux de paquets de sorte qu'une nouvelle classification de paquets déjà classifiés peut être évitée.
