Patent number: 10594581Abstract: A system includes first and second cache servers, a domain name server, and a route controller. The cache servers respond to an anycast address. The first and second cache servers respond to first and second unicast addresses respectively. The router controller determines if the first cache server is non-overloaded, overloaded, or offline. The route controller instructs the domain name server to provide the second unicast address when the status is overloaded or offline, and modifies 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 receives a request from a requestor, and provides an anycast address to the requestor when the status of the first cache server is non-overloaded, and provides the second unicast address to the requestor when the status of the first cache server is offline or overloaded.Type: GrantFiled: July 23, 2018Date of Patent: March 17, 2020Assignee: AT&T Intellectual Property I, L.P.Inventors: Mario A. Santoro, Herani Brotman, Alan L. Glasser, James Miros, Oliver Spatscheck, Jacobus E. Van der Merwe

Patent number: 9667516Abstract: 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.Type: GrantFiled: October 2, 2015Date of Patent: May 30, 2017Assignee: AT&T INTELLECTUAL PROPERTY I, L.P.Inventors: Mario A.
