Abstract

La présente invention concerne un procédé de communication de dispositif réseau et un dispositif réseau. Le procédé comprend les étapes suivantes : lors de l'accès à un réseau, un dispositif réseau obtient un message de découverte de voisin (ND) envoyé par un dispositif voisin, le message de ND portant des informations d'un serveur de gestion de réseau et les informations comprenant une adresse de protocole Internet (IP) ou un localisateur uniforme de ressources (URL) ou un nom de domaine ; le dispositif réseau obtient les informations du serveur de gestion de réseau, sur la base du message de ND ; et le dispositif réseau communique avec le serveur de gestion de réseau à l'aide des informations du serveur de gestion de réseau. Le procédé de configuration automatique de dispositif réseau et le dispositif réseau de la présente invention activent automatiquement une configuration d'initialisation pour un dispositif réseau, réalisant ainsi une configuration automatique du dispositif réseau, ce qui réduit la complexité d'une gestion globale du travail et simplifie considérablement les surcharges de gestion de la configuration automatique.
