US 11,606,331 B1 · Systems and methods for processing requests for content of a content distribution network

Abstract

Improved methods for retrieval of content from CDNs is provided that includes a rendezvous controller that receives information of an identification of content being requested and an estimated location of a content requesting device. Based on this information, the rendezvous system identifies a server within a CDN from which the requested content may be retrieved. The selected server may be based on a repeatable hash function such that the likelihood that the content being requested is cached at the selected server. Steering requests to a server of the CDN which may have the content cached may reduce the number of servers within the CDN with the same cached content, particularly for the highest requested content. The rendezvous system may then return a corresponding domain name associated with the selected server and that can be subsequently submitted to a DNS for resolution to the IP address of the identified server.

Claims13

Dependent claims

A method of processing content requests comprising:

receiving, at a networking device, a request for content comprising each of a content identifier associated with a content file and a location identifier associated with a geographic location of a content-receiving device;
generating, by the network device and based on the content identifier, a server identifier corresponding to a server in the geographic location;
transmitting, to a requesting device, a domain name comprising a server identifier corresponding to the server, an indication of the geographic location of the content-receiving device, and a shared domain identifier, wherein a domain name system (DNS) utilizes the domain name to obtain an identification of the server from a database associated with the shared domain identifier;
and
executing a hashing function with the content identifier as an input variable, wherein the output of the hashing function corresponds to the server identifier of the server.
