Abstract

L'invention concerne des appareils et des techniques de distribution à temps de paquets de données par l'intermédiaire d'une série de noeuds de calcul dans un réseau. Un noeud reçoit un paquet de données d'une interface réseau d'entrée, applique une heure admissible la plus précoce pour la transmission du paquet de données à un noeud suivant sur la base de données extraites d'un champ d'information dans le paquet de données, détermine une heure de transmission pour le paquet de données qui n'est pas antérieure à l'heure admissible le plus précoce pour la transmission, stocke, dans le champ d'information du paquet de données, une indication d'un retard minimum pour le paquet de données au niveau du noeud suivant, et transmet le paquet de données au noeud suivant par l'intermédiaire d'une interface réseau de sortie.
