METHOD AND APPARATUS FOR UPDATING RESOURCE RECORDS IN A NAME-SERVER DATABASE

摘要

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.
