Abstract
A method, operable in a framework wherein resources of a content provider may be delivered to clients from at least two distinct content delivery networks (CDNs). Responsive to a client request, one of the CDNs is selected, the selection being based at least in part on one or more policies set by the content provider. The client is provided with information associated with the selected CDN. The information may be a domain name such as a CNAME for the selected CDN. The policies may include a load share policy that specifies a relative load share for each CDN, and the selecting may attempt to satisfy the load share policy. Updated content provider policies may be obtained, at regular intervals.
