Abstract

La présente invention se rapporte à un procédé, à un appareil et à un système adaptés pour surveiller un flux de service. Le procédé selon l'invention comprend les étapes suivantes : un dispositif de surveillance de flux de service détermine un paramètre de surveillance de bande passante d'un premier flux de service d'un premier service ; et le dispositif de surveillance de flux de service transmet le paramètre de surveillance de bande passante du premier flux de service à un dispositif de règle de politique, de telle sorte que le dispositif de règle de politique configure une règle de surveillance de bande passante pour le premier flux de service et transmette la règle de surveillance de bande passante à un dispositif de création de rapport d'événement. L'invention est caractérisée en ce que la règle de surveillance de bande passante est une règle basée sur le paramètre de surveillance de bande passante du premier flux de service et qu'elle est utilisée pour déterminer si la bande passante du premier flux de service est anormale, ou non. Dans les modes de réalisation de la présente invention, le paramètre de surveillance de bande passante du premier flux de service est transmis au dispositif de règle de politique, de telle sorte que le dispositif de règle de politique configure la règle de surveillance de bande passante correspondante et que le dispositif de création de rapport d'événement surveille la bande passante du premier flux de service sur la base de la règle de surveillance de bande passante. De cette manière, le dispositif de création de rapport d'événement peut surveiller l'exception de bande passante du premier flux de service, et le gaspillage des ressources allouées peut ainsi être évité.
