摘要： 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.

摘要： A content delivery system includes a cache server, a domain name server, and a redirector. The domain name server is configured to receive a request for a cache server address, and provide an IPv6 anycast address. The redirector is configured to receive a content request addressed to the IPv6 anycast address from a client system, receive load information from the cache server, and determine if the cache server is available. The redirector is further configured to forward the content request to the cache server when the cache server is available. The cache server is configured to receive the content request forwarded from the redirectors, send a response to the content request to a client system, the response including an IPv6 unicast address of the cache server as a source address, an IPv6 unicast address of the client system as a destination address, and the IPv6 anycast address as a home address, and provide the content to the requestor.
