REQUEST ROUTING USING POPULARITY INFORMATION

摘要

A system, method and computer-readable medium for request routing based on content popularity information are provided. A client computing device transmits a first DNS query to a content delivery network service provider. The content delivery network service provider transmits an alternative resource identifier in response to the client computing device DNS query. The alternative resource identifier is selected as a function of popularity information pertaining to the requested resource. The client computing device then transmits a second DNS query to the content delivery network service provider. The content delivery network service provider can then either resolve the second DNS query with an IP address of a cache component or transmit another alternative resource identifier that will resolve to the content delivery network service provider. The process can repeat until a DNS nameserver resolves a DNS query from the client computing device.

主权项

1. A computer-implemented method comprising:
obtaining a DNS query at a first DNS nameserver from a client computing device, the DNS query including at least a portion of a first uniform resource locator associated with a resource, wherein a popularity identifier is included in a DNS portion of the at least a portion of the first uniform resource locator accessible to the first DNS nameserver, and wherein the popularity identifier is associated with the resource; processing the at least a portion of the first uniform resource locator at the first DNS nameserver to obtain the popularity identifier; obtaining an alternative resource identifier in response to the DNS query, wherein the alternative resource identifier is selected, at least in part, as a function of the popularity identifier; and transmitting the alternative resource identifier to the client computing device.
