Abstract

Selon un mode de réalisation, la présente invention concerne un procédé et un dispositif terminal permettant de traiter un paquet de protocole de routage. Le procédé est appliqué à un premier dispositif de bord de réseau d'un premier centre de données (DC). Avant que le premier dispositif de bord de réseau annonce un paquet de protocole de routage à un second dispositif de bord de réseau, ajouter un premier identifiant d'attribut de connexion de réseau au paquet de protocole de routage, et après que le paquet de protocole de routage est utilisé pour permettre au second dispositif de bord de réseau d'acquérir des informations concernant le premier paquet de protocole de routage, déterminer, selon la première séquence d'identifiants d'attribut de connexion du paquet de protocole de routage, s'il existe la possibilité d'une boucle dans la route du paquet de protocole de routage. Dans le mode de réalisation de la présente invention, un dispositif de bord de réseau de limite peut déterminer automatiquement, selon l'identifiant d'attribut de connexion de réseau transporté par le paquet de protocole de routage reçu, s'il existe la possibilité d'une boucle dans la route du paquet de protocole de routage, de sorte que des boucles de paquets de protocole de routage soient évitées, évitant ainsi des boucles de paquets de données.
