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.
