Abstract
A domain name server includes a processor configured to receive a request from a requester for an edge cache address, identify a first edge cache serving content requests to an anycast address from the requester, and determine a load of first edge cache. The processor is further configured to provide unicast address of an alternate edge cache to requester in response to the request when the load exceeds a threshold or to provide anycast address to requester in response to request when the load is below the threshold.
