摘要： A system includes first and second cache servers a domain name server, and a route controller. The cache servers are each configured to respond to an anycast address. Additionally, the first cache server is configured to respond to a first unicast address, and the second cache server is configured to respond to a second unicast address. The router controller configured to determine wither the status of the first cache server is non-overloaded, overloaded, or offline. The route controller is further configured to instruct the domain name server to provide the second unicast address when the status is overloaded or offline, and modify routing of the anycast address to direct a content request sent to the anycast address to the second cache server when the status is offline. The domain name server is configured to receive a request from a requestor for a cache server address. Additionally, the domain name server is configured to provide an anycast address to the requestor when the status of the first cache server is non-overloaded, and provide the second unicast address to the requestor when the status of the first cache server is offline or overloaded.

摘要： A cache server for providing content includes a processor configured to receive a first datagram from a client system sent to an anycast address, send a response datagram to the client system in response to the first datagram, receive a request datagram from the client system sent to the anycast address, and send a batch of content datagrams to the client system. The first datagram includes a universal resource locator corresponding to the content. The response datagram includes a content identifier for the content. The request datagram includes the content identifier, an offset, and a bandwidth indicator. The batch of content datagrams includes a portion of the content starting at the offset.

摘要： A system including first and second servers, a domain server, and a route controller is disclosed. 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.
