Abstract

L'invention concerne un procédé de traitement de flux de données reçues et transmises par paquets dans un processeur de paquets. Ce procédé consiste (A) à recevoir un flux de paquets dans un pipeline, chaque paquet comprenant essentiellement un en-tête et une section de charge utile, à analyser l'en-tête du paquet pour en déterminer la validité, les informations de synchronisation et les informations d'adressage, à effectuer, parallèlement à l'analyse de l'en-tête, un contrôle de validité de la charge utile, à procéder éventuellement à un décryptage de la charge utile si celle-ci est cryptée, et, si au moins l'un des contrôles échoue au cours des étapes susmentionnées, à mettre fin au traitement du paquet. Ledit procédé consiste également (B) à créer un pipeline de transmission, à recevoir, par l'intermédiaire de ce pipeline, une charge utile en provenance d'un hôte et au moins une adresse de destination, à créer un en-tête associé et à ajouter des informations de validité à cet en-tête, à associer ledit en-tête à la charge utile et à les réacheminer dans le pipeline, à décrypter éventuellement la charge utile, et, si une erreur survient au cours des opérations susmentionnées, à mettre fin au traitement dudit paquet à transmettre.
