Abstract

Des modes de réalisation de la présente invention peuvent être appliqués au domaine de la surveillance d'état de la technologie infonuagique, et portent sur un procédé de surveillance de qualité d'un service en nuage, et un produit associé. Le procédé consiste à : recevoir un paquet de test de réseau envoyé d'un client à un hôte en nuage dans un serveur, et envoyer le paquet de test de réseau à l'hôte en nuage ; recevoir des données de résultat du paquet de test de réseau renvoyées par l'hôte en nuage, et envoyer les données de résultat au client ; s'il existe des paquets de test de réseau envoyés au serveur par le client et par des clients autres que le client, intercepter les paquets de test de réseau envoyés à l'hôte en nuage par le client et par les clients autres que le client ; et collecter des statistiques concernant les paquets de test de réseau envoyés à l'hôte en nuage pour obtenir un résultat statistique, dans le cas où le résultat statistique relève d'une règle prédéterminée de détection de l'hôte en nuage d'une manière centralisée, détecter le serveur pour obtenir un résultat de détection, et envoyer le résultat de détection au client. D'une part, des raisons peuvent être déterminées avec précision pour des défauts de qualité d'un service en nuage afin de garantir la qualité du service en nuage, et d'autre part, la possibilité de subir une attaque par un paquet de test de réseau peut être réduite et ainsi la sécurité est améliorée.
