  • Patent number: 9565157
    Abstract: Comprises identifying an end point or content server that can best serve an end user that sent a DNS request to an ISP DNS resolver, given a geographically distributed network of end points. In particular, the method further comprises using the end points themselves and a tracker to identify and notify to the end user the IP addresses of the least-loaded and closest end points that can best serve the content request.
    Type: Grant

  • Patent number: 8868682
    Abstract: A method of optimizing the design of a Tracker in P2P applications to support DVD features, the method including determining for each peer and video operation the time T and jump point Pj, generating a hash key HKj for each peer, the hash key having a value Kj=(Pj?T)/C, where C>=1 is the granularity of the system, and grouping the peers with the same hash-key, where the system is designed to provide good viewer experience while supporting DVD features like pause, forward and backward jump operations.

  • Publication number: 20140165118
    Abstract: The method comprises the management and delivery of a requested live stream using a P2P-based architecture, where peers exchanging content with one another are end points of a CDN. The delivery of the requested live stream to one or more end users is performed from one or more of said end points. The requested live stream is split into segments that the serving end points, preferably, obtains from neighbouring end points and/or from the origin server of the live stream using a scheduling algorithm and depending on the availability of segments thereof. The end point is designed for implementing the method of the invention.

  • Publication number: 20140149548
    Abstract: It comprises using buckets as logical containers for content files, and associating meta-data to said buckets, wherein said associating of meta-data comprises the association of two kinds of meta-data: file system meta-data and content distribution meta-data. The latter includes attributes or properties for specific use in a CDN system, and the method comprises using said content distribution meta-data for managing the content delivery in a CDN service.

  • Publication number: 20140052822
    Abstract: The system comprises a plurality of CDNs, each defining an operating business (OBi) having a its respective local origin server (OSi), and computing means for performing the interconnection of said plurality of CDNs, where said computing means comprises of a global origin server (OSG) that coordinates the formation of a global network by connecting to the local origin servers (OS{i}). The method comprises using a global origin server for coordinating the formation of a global network by its connection to CDN local origin servers.

  • Publication number: 20130132549
    Abstract: The method comprises modelling a delay-tolerant dynamic network comprising time-varying links transforming it into a static time-expanded network graph, and managing bulk data transfer on the basis of said static time-expanded network graph. The device comprises a scheduler unit with processing capabilities implementing an algorithm which processes arc costs (cijt) and storage costs (pit) as per the method of the first aspect of the invention.
