Abstract

L'invention concerne un procédé et un système de gestion de communication de dispositif de réseau local, ainsi qu'un dispositif de passerelle. Un dispositif de passerelle préétablit une table de gestion de communication d'une relation de mappage entre des informations d'attribut de dispositif concernant un dispositif LAN, un type de dispositif et une connexion WAN utilisée par le dispositif LAN pour accéder à une ressource de réseau. Lorsque le dispositif LAN envoie des informations de communication au dispositif de passerelle, le dispositif de passerelle peut déterminer la connexion WAN utilisée pour envoyer les informations de communication en fonction de la table de gestion de communication et des informations d'attribut de dispositif transportées dans les informations de communication, et envoie les informations de communication.
