Using virtual domain name service (DNS) zones for enterprise content delivery

摘要

A domain to be published to an enterprise ECDN is associated with a set of one or more enterprise zones configurable in a hierarchy. When a DNS query arrives for a hostname known to be associated with given content within the control of the ECDN, a DNS server responds by handing back an IP address, by executing a zone referral to a next (lower) level name server in a zone hierarchy, or by CNAMing to another hostname, thereby restarting the lookup procedure. At any level in the zone hierarchy, there is an associated zone server that executes logic that applies the requested hostname against a map. A name query to ECDN-managed content may be serviced in coordination with various sources of distributed network intelligence.
