Abstract

Un système, un procédé et un appareil permettant d'améliorer l'efficacité de compression d'un protocole de communication pour une utilisation sur des liaisons de communication à largeur de bande limitée (250, 255, 550). D'une part, l'invention utilise la connaissance de la structure et le contenu des protocoles de communication pour constituer un dictionnaire statique (220, 420, 430) ou un arbre code binaire statique, ce qui permet d'améliorer considérablement l'efficacité de compression. D'autre part, l'invention permet d'obtenir un dictionnaire statique et dynamique combiné (520, 540) ou un arbre code binaire pour réaliser une compression de protocole de communication. L'arbre code binaire statique ou le dictionnaire statique (220, 420, 430) est construit par l'étude de flux de protocoles de données dans leurs conditions d'utilisation prévues.
