NETWORK MEASUREMENT-BASED ADDRESS SELECTION METHOD FOR DNS NODE

摘要

The present invention relates to a network measurement-based address selection method for a DNS node. The method comprises: first, dividing a DNS service region into a plurality of user regions according to a feature of users, the feature of the users being preferably a geographic feature; second, measuring network delays between the user regions, and obtaining a DNS node address selection scheme with a highest efficiency by minimizing an average delay of the users; obtaining a DNS node address selection scheme with a highest fairness by minimizing a maximum delay of the users; and then, obtaining a DNS node address selection scheme on which both efficiency and fairness are considered. In the present invention, network address selection of a DNC authoritative server is optimized based on actual internet data, a DNS address selection model based on a network delay is established, a model solution method is provided, a resolution delay can be effectively shortened, and user experience can be improved.
