Abstract

A content delivery network includes first and second sets of cache servers, a domain name server, and an anycast island controller. The first set of cache servers is hosted by a first autonomous system and the second set of cache servers is hosted by a second autonomous system. The cache servers are configured to respond to an anycast address for the content delivery network, to receive a request for content from a client system, and provide the content to the client system. The first and second autonomous systems are configured to balance the load across the first and second sets of cache servers, respectively. The domain name server is configured to receive a request from a requestor for a cache server address, and provide the anycast address to the requestor in response to the request. The anycast island controller is configured to receive load information from each of the cache servers, determine an amount of requests to transfer from the first autonomous system to the second autonomous system; send an instruction to the first autonomous system to transfer the amount of requests to the second autonomous system.
