One embodiment of the present invention provides a system for updating resource records in a name-server database. During system operation, a network node creates an update-request message containing a set of resource-record updates, and a requested lease, which specifies the length of time for which the name server is being requested to store the resource-record updates. Next, the network node sends the update-request message to a name server, which is part of a distributed system that provides a global naming service. The network node then receives a response message from the name server, wherein the response message contains a granted lease, which specifies the length of time for which the name-server database will store the resource-record updates.

Un mode de réalisation porte sur un système de mise à jour d'enregistrements de ressources dans une base de données de serveurs de noms. Pendant le fonctionnement du système, un noeud de réseau crée un message de demande de mise à jour contenant un ensemble de mises à jours d'enregistrements de ressources, et une demande de bail, qui précise la durée pendant laquelle le serveur de noms doit stocker les mises à jour d'enregistrements de ressources. Par la suite, le noeud de ressources envoie le message de demande de mise à jour à un serveur de noms qui fait partie d'un système réparti fournissant un service de dénomination global. Le noeud de réseau reçoit alors un message de réponse du serveur de noms, ce message de réponse contenant un bail accordé, qui précise la durée pendant laquelle la base de données de serveurs de noms stockera les mises à jour d'enregistrements de ressources.
