Abstract

L'invention appartient au domaine technique des communications sans fil et concerne en particulier un procédé, un routeur, et un processeur de réseau pour contrôler l'état d'un port. L'invention résout un problème de complexité lié à la suppression d'un état fermé d'un dispositif détaché. L'invention fournit un procédé de commande de l'état d'un port. Le procédé comprend les étapes suivantes: un premier port dans un état fermé d'un premier dispositif reçoit un paquet d'instruction envoyé par un second port d'un second dispositif, et le premier port envoie le paquet d'instruction à un processeur de réseau (NP) du premier dispositif ; le NP détermine si le paquet d'instruction est un paquet ordonnant la suppression d'un état fermé d'un port ; dans l'affirmative, il envoie le paquet d'instruction à une CPU du premier dispositif ; et la CPU reçoit le paquet d'instruction envoyé par le NP et ordonne alors la suppression de l'état fermé du premier port. Le procédé contrôle l'état d'un port en envoyant un paquet d'instruction, et peut exécuter une opération à distance pour supprimer un état fermé d'un port de dispositif sans qu'un opérateur doive accéder à une salle des machines abritant le dispositif pour exécuter l'opération, ce qui simplifie l'opération et économise du temps et de la main-d'œuvre.
