Abstract

L'invention concerne un procédé et un appareil comprenant la configuration d'une liaison physique unique entre une passerelle et un boîtier décodeur sous forme de deux liaisons logiques entre ladite passerelle et ledit boîtier décodeur, la réception de données en provenance du boîtier décodeur, la mise à jour d'un en-tête des données en définissant un identifiant basé sur un port à la première valeur, la détermination du fait qu'une adresse dans l'en-tête des données est une adresse de la passerelle, la transmission des données à un port du réseau étendu en pont, si l'adresse dans l'en-tête des données n'est pas une adresse de la passerelle, la mise à jour de l'identifiant basé sur un port à une seconde valeur, si l'adresse dans l'en-tête des données est l'adresse de la passerelle, et la transmission des données à un port internet du réseau étendu.
