Abstract

L'invention concerne un procédé et un dispositif pour modifier de manière sélective des données de fonctionnement d'un composant de réseau dans un réseau comprenant au moins deux composants, des données, notamment des données de communication, pouvant être traitées dans chaque composant de réseau et les composants de réseau pouvant être regroupés pour former un groupement au sein du réseau. La modification de données de fonctionnement d'un composant de réseau dans un groupement influence traditionnellement le traitement des données du groupement dans son ensemble. Une détermination de classification permet d'après le procédé selon l'invention de sélectionner de manière ciblée uniquement les composants de réseau effectivement à modifier et de les séparer du réseau pour la modification des données de fonctionnement. Une application appelant le composant de réseau à modifier est informée de la modification des données de fonctionnement et interrompt la communication avec le composant de réseau à modifier pour la durée de la modification des données de fonctionnement. Le traitement des données au sein du groupement et avec ce dernier est ainsi influencé seulement dans une mesure très limitée par la modification des données de fonctionnement d'un composant de réseau.
