The first and second servers are configured to respond to an anycast address and to first and second unicast addresses respectively. The route controller is configured to determine whether the first cache server is non-overloaded, overloaded, or offline, and may instruct the domain name server to provide to provide the second unicast address when the status is overloaded or offline. Routing of the anycast address may be modified so as to direct a content request sent to the anycast address to the second cache server when the status is offline. The domain name server may receive a request for a cache server address and provide the anycast address to the requestor when the status is non-overloaded, and provide the second unicast address when the status is offline or overloaded."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Integrated adaptive anycast for content distribution","description":"A system including first and second servers, a domain server, and a route controller is disclosed.
