Patent number: 11323510Abstract: A load-balancing cluster includes a switch having a plurality of ports; and a plurality of servers connected to at least some of the plurality of ports of the switch. Each server is addressable by the same virtual Internet Protocol (VIP) address. Each server in the cluster has a mechanism constructed and adapted to respond to connection requests at the VIP by selecting one of the plurality of servers to handle that connection, wherein the selecting is based, at least in part, on a given function of information used to request the connection; and a firewall mechanism constructed and adapted to accept all requests for the VIP address for a particular connection only on the server that has been selected to handle that particular connection. The selected server determines whether it is responsible for the request and may hand it off to another cluster member.Type: GrantFiled: August 7, 2020Date of Patent: May 3, 2022Assignee: Level 3 Communications, LLCInventors: Maksim Yevmenkin, David Fullagar, Christopher Newton, Jeffrey Koller

Patent number: 10255229Abstract: Provided are computer-implemented methods and systems for performing media resource storage and management. The computer-implemented method and system implemented as a request manager is capable of monitoring requests for media resources in a content delivery network. For each monitored request, the request manager determines whether to generate a multifile for the requested media resource. For example, the request manager can first determine whether the media resource is eligible for multifile generation. If eligible, the request manager then determines whether the media resource has reached a popularity threshold. If the media resource has reached the popularity threshold, the request manager initiates generation of the multifile for the requested media resource. Generally, the generated multifile is stored in a storage system associated with the content delivery network.Type: GrantFiled: January 3, 2012Date of Patent: April 9, 2019Assignee: LEVEL 3 COMMUNICATIONS, LLCInventors: William Crowder, Jeffrey Koller, David Fullagar

Publication number: 20030065762Abstract: A framework for delivery of Internet content includes a subscriber server network; and at least one domain name server constructed and adapted to provide policy-based domain name service, wherein, in response to a request to resolve a hostname, the domain name server resolves the hostname to at least one address corresponding a server in the subscriber server network based on at least one policy consideration. The framework may include a content delivery network, distinct from the subscriber server network, wherein, in response to a request to resolve a hostname, the domain name server provides at least one addresses of a server in the content delivery network based at least on the location of the requestor and other policy considerations. An address returned by the domain name server is selected based on one or more of: (a) geographic policies; (b) load share policies; (c) overflow policies; and (d) network aware policies.Type: ApplicationFiled: September 30, 2002Publication date: April 3, 2003Applicant: Cable & Wireless Internet Services, Inc.Inventors: Paul E.
