Publication number: 20240106918Abstract: A content delivery network (CDN) includes a plurality of CDN components including at least one CDN rendezvous mechanism and at least one control core. The CDN components are controlled by control core data from the at least one control core. Some CDN components obtain CDN resources including control core data from at least some other CDN components. The CDN components use the CDN rendezvous mechanism to select one or more CDN components from which to obtain CDN resources.Type: ApplicationFiled: November 30, 2023Publication date: March 28, 2024Applicant: Level 3 Communications, LLCInventors: Laurence R. Lipstone, William Crowder, Jeffrey G. Koller, David Fullagar, Maksim Yevmenkin, Christopher Newton

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: 10911531Abstract: A network includes a first tier of servers, a second tier of servers and a third tier of servers. The first tier of servers comprises a plurality of primary servers capable of responding to requests. The plurality of primary servers includes at least one dynamic server having a load share characteristic that is dynamically altered during a first period in time and at least one static server having a constant load share characteristic during the first period in time. The second tier of servers includes at least two first layer overflow servers. Each of the first layer overflow servers is configured to provide response duties in the event that one or more of the primary servers is unavailable or overloaded. The third tier of servers comprising at least two second layer overflow servers.Type: GrantFiled: October 29, 2018Date of Patent: February 2, 2021Assignee: Level 3 Communications, LLCInventors: Paul E.
