Abstract

Selon l'invention, les listes d'attente de communication multiples facilitent la gestion du trafic de données d'entrée et de sortie d'un dispositif numérique d'un réseau. Une fonction de tri configurable trie les données selon des caractéristiques multiples en listes d'attente logistiques. Un contrôleur configurable établit un ordre de priorité des données en une liste d'attente d'activation qui transmet les données à un réseau ou au dispositif informatique numérique. Cette invention ne nécessite pas d'administration ou de systèmes matériels ou logiciels supplémentaires. Elle ne dépend pas des schémas d'assignation de descripteurs et de schémas d'ordres de priorité et n'interfère pas avec ceux-ci. Cette invention utilise des application de carte et de pilote de périphérique de réseau associées à des systèmes pouvant produire et/ou recevoir un volume de trafic important et/ou varié.
