Abstract

The invention discloses a method, device and apparatus for deploying client subsystem functions and a medium. The method comprises the steps that a local DNS (Domain Name System) acquires subregions of clients according to client addresses sending DNS query requests; the local DNS judges whether the DNS query requests are the first-time requests in the subregions of clients or not; if the DNS query requests are the first-time requests in the subregions of the clients, the local DNS fetches subregion mapping addresses corresponding to the subregions of the clients; the local DNS sends updated DNS query requests to an authoritative server; the authoritative server determines resolution addresses based on the subregion mapping addresses corresponding to the subregions of the clients; the local DNS caches response messages and sends the response messages to the clients; and if the DNS query requests are not the first-time requests and the duration between this-time requests and the last-time requests does not exceed TTL, the local DNS queries the response messages in cache subregions and sends the response messages to the clients. According to the method, device and apparatus for deploying the client subsystem functions and the computer readable memory medium provided by the embodiment of the invention, the resource consumption of related servers can be reduced.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a method, device, device and computer-readable storage medium for deploying functions of a client subsystem in a domain name system. Background technique [0002] With the rapid growth of users, many Internet content providers generally use a content delivery network (Content Delivery Network, CDN) to provide content services to users. Internet content providers generally implement CDN scheduling through authoritative servers. The authoritative server can return different domain name system (Domain Name System, DNS) resolution addresses for the same domain name according to the topological location of the user network, and dispatch user access to the most optimized CDN content node. [0003] A new option is added to the extended header of the DNS message, which carries the address information of the initial DNS requester, and the content in the option can be relayed to the autho...
