Definitions

  • the authoritative DNS server (114) sends a DNS response (responsive to the fourth DNS query) to the local DNS (104) .
  • the authoritative DNS server may be configured to send a DNS response to the local DNS.
  • the DNS response includes the selected canonical domain name in a resource record.
  • the resource record that includes the selected canonical domain name may be sent by the authoritative DNS server to the local DNS server as a “CNAME” resource record.
  • the authoritative DNS server may be configured to interact with other DNS counterparts in full compliance with the DNS standards, such as when communicating with other DNS servers such as the local DNS server that sent the alias domain name in DNS queries to the authoritative DNS server.
  • Some or all of the components, devices, systems, modules, etc., in the example configuration of FIG. 3A may be operatively linked through one or more computer networks such as one or more of wide area networks, local area networks, customer premises transport networks, wireless networks, wireline based networks, optical networks, carrier networks, etc.
  • the authoritative DNS server (114) may be configured to determine whether a resource record for the domain name has been defimed in a local DNS cache, a zone file, a configuration data store, etc., of the authoritative DNS server (114) .
  • the authoritative DNS server (114) determines that a “CX” resource record (e.g., 400 of FIG. 4, etc. ) for the domain name (as an alias domain name) has been defined in a local DNS cache, a zone file, a configuration data store, etc., of the authoritative DNS server (114) .
  • the resource record (400) defines a mapping from the domain name “www. sina. com.
  • the CDN client system (352) can effectively redirect content access requests subsequent to the DNS queries to the CDNs (356) represented by the canonical domain names as defined with the “CX” resource record (400) .
  • a computing device comprising one or more processors and one or more storage media storing a set of instructions which, when executed by the one or more processors, cause performance of any of the foregoing methods.

Abstract

Un serveur de système de noms de domaine (DNS) est configuré avec un mappage d'un nom de domaine par pseudonyme sur une pluralité de noms de domaine canoniques. Une interrogation DNS pour le nom de domaine par pseudonyme est reçue par le serveur DNS. En réponse à la réception de l'interrogation DNS, le serveur DNS sélectionne un nom de domaine canonique de la pluralité de noms de domaine canoniques, sur lequel le nom de domaine par pseudonyme est mappé.
