  • Publication number: 20120254343
    Abstract: Content delivery networks (CDNs) deliver content objects for others is disclosed. End user computers are directed to an edge server for delivery of a requested content object by a universal resource indicator (URI). When an edge server does not have a copy of the content object from the URI, information is successively passed to ancestor servers within a hierarchy until the content object is found. There can be different hierarchies designated for different URIs or times at which requests are received. Once the content object is located in the hierarchical chain, the content object is passed back down the chain to the edge server for delivery.

  • Patent number: 8274909
    Abstract: Techniques for modifying the performance of a transport layer protocol in response to a request for content are disclosed. A connection can be established between a content distribution server and an end user computer according to preconfigured parameters. When a request for content is received over the connection, the content distribution server can determine one or more parameters relating to the performance of the connection using information from the request. The content distribution server can modify the connection at the transport layer according to the one or more parameters. Thereafter, the transport layer can manage delivery of the requested content to the end user computer in accordance with the modified parameters. In various embodiments, the content distribution server includes a modified TCP protocol stack which adjusts timing, pacing, and buffer allocation associated with a connection in response to requests from an application-layer data source.

  • Patent number: 8255557
    Abstract: Techniques for the distribution of content objects in a content delivery network (CDN) are disclosed. In one embodiment, a CDN distribution server detects the availability of a content object and determines whether the content object is a candidate for distribution. The distribution server may detect the availability of the content object in response to a provider making new or updated content available at a content site or a location within the CDN. The distribution server obtains identifying information for a candidate content object and determines a select portion of the content object to be distributed within the CDN. The select portion can be a predetermined number of bytes located at a predetermined position in the content object, the size and location of which may be determined according to content-specific mapping data. The distribution server may push the select portion of the content object to one or more groups of CDN edge servers absent an end-user request.

  • Patent number: 8250368
    Abstract: A system and method for delivering content to end users encrypted within a content delivery network (CDN) for content originators is disclosed. CDNs transport content for content originators to end user systems in a largely opaque manner. Caches and origin servers in the CDN are used to store content. Some or all of the content is encrypted within the CDN. When universal resource indicators (URIs) are received from an end user system, the CDN can determine the key used to decrypt the content object within the CDN before delivery. Where there is a cache miss, an origin server can be queried for the content object, which is encrypted in the CDN.
