Abstract
A content delivery network (CDN) performs time varying traffic allocation. The network includes: one or more edge servers that store content corresponding to a domain name that is associated with a content provider, and are configured to deliver the content to end users in response to requests received at the edge servers from the end users; analytics information characterizing the CDN; and a traffic engine that periodically evaluates a service function as having a serve value or a shunt value for the domain name, based at least in part on the analytics information. The traffic engine transmits one or more IP addresses of the edge servers to an interface to a domain name service (DNS) while the service function has the serve value for the domain name; and transmits alternate domain name information of a different network to the interface while the service function has the shunt value.
