Abstract

L'invention concerne un procédé de surveillance de dispositif de réseau, un système, un dispositif de routage et un support de stockage, ledit procédé comprenant les étapes suivantes : surveillance d'une liaison de données de liaison montante d'un dispositif de réseau surveillé, et interception d'un paquet de données de liaison montante à partir de la liaison de données de liaison montante ; analyse du paquet de données de liaison montante pour identifier le dispositif de réseau d'origine qui a téléversé le paquet de données de liaison montante ; interrogation, à partir d'une première table de routage de transmission, d'une pluralité de dispositifs de gestion de réseau cible qui surveillent le dispositif de réseau d'origine ; transmission du paquet de données de liaison montante à chacun desdits dispositifs de gestion de réseau cible de sorte que chaque dispositif de gestion de réseau cible surveille le dispositif de réseau d'origine. Le procédé décrit surmonte la limitation de l'état de la technique selon lequel un dispositif de réseau peut uniquement être surveillé par un dispositif de gestion de réseau, et peut éviter la nécessité de modifier les adresses de réseau des dispositifs de gestion de réseau sur chaque dispositif de réseau un à la fois en vue d'ajouter des dispositifs de gestion de réseau, et peut également éviter le réglage de l'adresse réseau de chaque dispositif de réseau correspondant au dispositif de gestion de réseau lors de l'ajout de dispositifs de réseau à surveiller, ce qui réduit le coût de mise en place d'une surveillance de dispositif de réseau.
