Abstract

L’invention concerne un procédé et un client destinés à l’implémentation de la détection des performances du service DHCP, comprenant les étapes suivantes : tout d’abord, le côté client DHCP transmet le message de demande de configuration au serveur DHCP à tester ; ensuite, en fonction de l’état du message de réponse reçu par le côté client DHCP à partir du serveur DHCP à tester, on détermine le résultat de la détection des performances du service DHCP. La présente invention peut réaliser de manière efficace la détection et la surveillance du protocole DHCPv6 dans le réseau IPv6. Elle peut connaître à temps l’état de fonctionnement du serveur DHCPv6 dans le réseau, découvrir à temps toute anormalité survenant, et intervenir auprès de l’utilisateur pour la résoudre. Il est donc important que la présente invention maintienne le fonctionnement normal du protocole DHCPv6 dans le réseau et procure le service DHCPv6 stable à partir du fournisseur au client.
