A communication system exchanges communications between end user devices, content delivery nodes (CDN) of a content delivery system, and a control system that selects CDNs of the content delivery system. The control system receives a domain name lookup request issued by an end user device for retrieving content cached by one or more CDNs of the content delivery system. The control system associates the end user device with a network performance profile to select a CDN of the content delivery system. The control system transfers a network address associated with the selected CDN for receipt by the end user device responsive to the domain name lookup request. |
