Abstract

La présente invention se rapporte à un procédé et à un système adaptés pour gérer un message Trap sur la base du protocole simple de gestion de réseau (SNMP, Simple Network Management Protocol). Le procédé selon l'invention comprend les étapes suivantes : après avoir détecté un événement d'alarme d'interface, un élément de réseau SNMP envoie un message Trap à un gestionnaire de réseau SNMP, ledit message Trap contenant des informations relatives à la position où l'événement d'alarme s'est produit ; sur la base des informations relatives à la position où l'événement d'alarme s'est produit, ces informations étant contenues dans le message Trap, le gestionnaire de réseau SNMP acquiert, auprès de l'élément de réseau SNMP, des informations relatives à l'interface sur laquelle l'événement d'alarme interface s'est produit ; et il compare les informations relatives à l'interface aux informations d'alarme qui sont contenues dans le message Trap ; d'autre part, si les informations relatives à l'interface sont identiques aux informations d'alarme, le gestionnaire de réseau SNMP vérifie que le message Trap est valide ; enfin, le gestionnaire de réseau SNMP déclenche une alarme. La solution technique de l'invention garantit que les messages Trap sont corrects, dans le contexte de la gestion SNMP. Elle améliore en outre la fiabilité de la transmission de messages Trap.
