Abstract

La présente invention concerne un procédé et un dispositif d'allocation d'adresse de protocole Internet (IP). Le procédé consiste : à diviser une carte réseau physique dans un équipement de locaux de client (CPE) en une première carte réseau logique et en une seconde carte réseau logique en tant que premier mode préétabli ; lorsqu'un terminal de client demande d'accéder au CPE, à allouer une adresse IP de réseau privé du CPE pour un terminal de client par l'intermédiaire d'un premier pont entre réseaux connecté à la première carte réseau logique, ou à allouer une adresse IP de réseau public au terminal de client par l'intermédiaire d'un second pont entre réseaux connecté à la seconde carte réseau logique. La présente invention traite un problème dans l'état de la technique associé dans lequel, lorsqu'une partie de terminaux de client accède uniquement à une ressource publique, les autres terminaux de client ne peuvent pas accéder à une ressource dans un produit de routeur, permettant ainsi d'améliorer l'expérience d'utilisateur.
