Publication number: 20240056416Abstract: Improved methods for retrieval of content from CDNs is provided that includes a rendezvous controller that receives information of an identification of content being requested and an estimated location of a content requesting device. Based on this information, the rendezvous system identifies a server within a CDN from which the requested content may be retrieved. The selected server may be based on a repeatable hash function such that the likelihood that the content being requested is cached at the selected server. Steering requests to a server of the CDN which may have the content cached may reduce the number of servers within the CDN with the same cached content, particularly for the highest requested content. The rendezvous system may then return a corresponding domain name associated with the selected server and that can be subsequently submitted to a DNS for resolution to the IP address of the identified server.Type: ApplicationFiled: October 26, 2023Publication date: February 15, 2024Applicant: Level 3 Communications, LLCInventor: Kevin C.

Patent number: 11076181Abstract: A system and corresponding method facilitate resolution of discontinuities in manifest files used in the distribution of stored content. Resolution of discontinuities includes identifying each of a discontinuity in a first manifest file and a corresponding entry in a second manifest file for the same or substantially similar content segment stored at a different location. A combined manifest file is then generated by inserting the entry of the second manifest file or otherwise inserting the location information of the second manifest file entry into the first manifest file. The systems and methods herein may be implemented at various locations within a system for providing content to a client device and may be implemented at various times in the process of generating or distributing content.Type: GrantFiled: June 23, 2020Date of Patent: July 27, 2021Assignee: Level 3 Communications, LLCInventor: Kevin C.

Patent number: 10778801Abstract: Aspects of the present disclosure involve systems, methods, computer program products, and the like, for a content delivery network (CDN) architecture utilizing one or more proxy cache devices between a requesting device and an edge cluster of the CDN. The proxy cache device is a relatively high-speed device compared to various possible devices making up one or more edge clusters. Thus, if the proxy has cached the requested content, it is capable of directly servicing the client content request at a faster rate than providing the content from the edge cluster. Otherwise, the proxy cache may request the content from an edge cluster and store the content for quick retrieval in response to additional requests for the content. In one embodiment, the proxy cache may perform an analysis of the request or a series of requests to determine if the content is cached at the proxy cache device.Type: GrantFiled: July 24, 2019Date of Patent: September 15, 2020Assignee: Level 3 Communications, LLCInventors: Joseph C.

Patent number: 10708767Abstract: Provided is a content delivery method and architecture for delivering content from a node in a content delivery network (CDN) using an anycast address to direct a requesting device to access a content manifest. The manifest server of the CDN may select the provided manifest based on information received from the requesting device and/or any other network information, may alter attributes of the manifest itself, or direct the requesting device to a different device or manifest server of the CDN to obtain the manifest. The selection of the manifest, alteration of the manifest, or new location to obtain the manifest causes the connection for content to occur at one or more servers accessible through a unicast address, rather than an anycast address.Type: GrantFiled: February 18, 2020Date of Patent: July 7, 2020Assignee: Level 3 Communications, LLCInventors: Joelle T.
