  • Patent number: 11677793
    Abstract: Stream-based data deduplication is provided in a multi-tenant shared infrastructure but without requiring “paired” endpoints having synchronized data dictionaries. Data objects processed by the dedupe functionality are treated as objects that can be fetched as needed. As such, a decoding peer does not need to maintain a symmetric library for the origin. Rather, if the peer does not have the chunks in cache that it needs, it follows a conventional content delivery network procedure to retrieve them. In this way, if dictionaries between pairs of sending and receiving peers are out-of-sync, relevant sections are then re-synchronized on-demand. The approach does not require that libraries maintained at a particular pair of sender and receiving peers are the same. Rather, the technique enables a peer, in effect, to “backfill” its dictionary on-the-fly. On-the-wire compression techniques are provided to reduce the amount of data transmitted between the peers.

  • Patent number: 11570234
    Abstract: An Internet infrastructure delivery platform (e.g., operated by a service provider) provides an overlay network (a server infrastructure) that is used to facilitate “second screen” end user media experiences. In this approach, first media content, which is typically either live on-demand, is being rendered on a first content device (e.g., a television, Blu-Ray disk or another source). That first media content may be delivered by servers in the overlay network. One or multiple end user second content devices are then adapted to be associated with the first content source, preferably, via the overlay network, to facilitate second screen end user experiences (on the second content devices).

  • Patent number: 9813284
    Abstract: A content delivery network (CDN) typically includes a mapping system for directing requests to CDN servers. One or more peer machines become associated with the CDN, and the CDN mapping system is then used to enable a given peer to locate another peer in the P2P network, and/or a CDN server. Using this hybrid approach, CDN customer content may be delivered from the CDN edge network, from the P2P network, or from both networks. In one embodiment, customer content is uploaded to the CDN and stored in the edge network, or in a storage network associated therewith. The CDN edge network is then used to prime the P2P network, which may be used to take over some of the content delivery requirements for the customer content. The decision of whether to use edge network or peer network resources for delivery may be based on load and traffic conditions.

  • Patent number: 9799033
    Abstract: Using cryptographic techniques, sensitive data is protected against disclosure in the event of a compromise of a content delivery network (CDN) edge infrastructure. These techniques obviate storage and/or transfer of such sensitive data, even with respect to payment transactions that are being authorized or otherwise enabled from CDN edge servers.

  • Publication number: 20170237705
    Abstract: Network architecture supports hosting and content distribution on a global scale. The architecture allows a Content Provider to replicate and serve its most popular content at an unlimited number of points throughout the world. The inventive framework comprises a set of servers operating in a distributed manner. The actual content to be served is preferably supported on a set of hosting servers (sometimes referred to as ghost servers). This content comprises HTML page objects that, conventionally, are served from a Content Provider site. A base HTML document portion of a Web page is served from the Content Provider's site while one or more embedded objects for the page are served from the hosting servers, preferably, those hosting servers near the client machine. By serving the base HTML document from the Content Provider's site, the Content Provider maintains control over the content.
