Abstract
A framework for delivery of Internet content includes a subscriber server network; and at least one domain name server constructed and adapted to provide policy-based domain name service, wherein, in response to a request to resolve a hostname, the domain name server resolves the hostname to at least one address corresponding a server in the subscriber server network based on at least one policy consideration. The framework may include a content delivery network, distinct from the subscriber server network, wherein, in response to a request to resolve a hostname, the domain name server provides at least one addresses of a server in the content delivery network based at least on the location of the requestor and other policy considerations. An address returned by the domain name server is selected based on one or more of: (a) geographic policies; (b) load share policies; (c) overflow policies; and (d) network aware policies.
