Abstract

La présente invention concerne un procédé permettant de commander le flux de l'alarme. Ledit procédé utilise d'abord un équipement de gestion pour informer un équipement géré des capacités de traitement de l'alarme de l'équipement de gestion, puis l'équipement géré soumet l'alarme à l'équipement de gestion en adoptant le flux de l'alarme correspondant selon les capacités de traitement d'alarme de l'équipement de gestion. L'invention porte aussi sur un équipement de gestion, un équipement géré et un système permettant de commander le flux de l'alarme.
