Abstract

Selon divers modes de réalisation, un dispositif électronique comprend un processeur, une mémoire et un module de communication. Le processeur peut : analyser un paquet de façon à identifier des caractéristiques du paquet ; sur la base des caractéristiques du paquet, déterminer s'il s'agit d'une opération de traitement d'un paquet initial ; s'il s'agit de l'opération de traitement d'un paquet initial, traiter le paquet sur la base d'une liste de règles définie au cours d'une session de protocole de commande de transfert de paquet (PFCP) ; puis générer des données de règles pour chaque flux de paquets et stocker les données de règles générées dans la mémoire.
