  • Publication number: 20120179839
    Abstract: A domain name service (DNS) resolver for returning Internet protocol (IP) addresses is provided in some embodiments of the invention. The DNS resolver includes a connection with an Internet application or device, wherein the connection receives domain name resolution requests that originates outside of the Internet. The DNS resolver also includes a direct DNS resolver that processes domain name resolutions without referring to the Internet after receiving a domain name resolution request and a recursing DNS resolver, wherein IP addresses are found by querying one or more DNS servers on the Internet after receiving domain name resolution requests. The DNS resolver includes an address store having a predetermined list of domain names and corresponding IP addresses that are specified from a point remote to the DNS resolver. The DNS resolver process the domain name resolutions for the predetermined list of domain names differently than other domain name resolutions.

  • Patent number: 8219645
    Abstract: One or more content delivery networks (CDNs) that deliver content objects for others is disclosed. Content is propagated to edge servers through hosting and/or caching. End user computers are directed to an edge server for delivery of a requested content object by a universal resource indicator (URI). When a particular edge server does not have a copy of the content object from the URI, information is passed to another server, the ancestor or parent server to find the content object. There can be different parents servers designated for different URIs. The parent server looks for the content object and if not found, will go to another server, the grandparent server, and so on up a hierarchy within the group. Eventually, the topmost server in the hierarchy goes to the origin server to find the content object. The origin server may be hosted in the CDN or at a content provider across the Internet.

  • Patent number: 8214450
    Abstract: According to the invention, a content delivery network (CDN) for delivering content objects from a content provider to a recipient is disclosed. The CDN includes a dynamic pricing engine and a second web location. The dynamic pricing engine is coupled to a first web location. The first web location, which is associated with a content provider, allows the recipient to order a content object. The delivery quote is solicited by the first web location for delivering a content object one or more times. The second web location delivers the content object to a recipient system of the recipient. The second web location is associated with the dynamic pricing engine. The dynamic pricing engine automatically produces the delivery quote, which is affected by at least one of the content object or a web location of the recipient system.

  • Publication number: 20120166591
    Abstract: A method and system for delivering content with a content delivery network (CDN) to a user computer is disclosed. After an initial request to a point of presence (POP) of the CDN for the location of the content object, an Anycast Internet protocol (IP) address is assigned. The user computer requests the content object which may find its way to the same or a different POP depending on what is closer in Internet terms. The request returns a POP-specific IP in a redirect such that the request resolves to the POP referenced in the immediately preceding sentence. One or more edge servers deliver the content object to the user computer.

  • Publication number: 20120166574
    Abstract: Techniques for partial object caching are disclosed. For example, a method includes receiving, at a content delivery network (CDN) from a end user device, a request for at least a portion of an object, retrieving the portion of the object from a content site and delivering the portion of the object to the end user device, and caching, in a partial object cache, the portion of the object. Further, the method may include receiving a subsequent request for the portion of the object, and retrieving, from the partial object cache the portion of the object and delivering the portion of the object in response to the subsequent request.

  • Patent number: 8204891
    Abstract: Various embodiments of the present invention include concept-service components of content-search-service systems which employ ontologies and vocabularies prepared for particular categories of content at particular times in order to score transcripts prepared from content items to enable a search-service component of a content-search-service system to assign estimates of the relatedness of portions of a content item to search criteria in order to render search results to clients of the content-search-service system. The concept-service component processes a search request to generate lists of related terms, and then employs the lists of related terms to process transcripts in order to score transcripts based on information contained in the ontologies.

  • Patent number: 8199752
    Abstract: Systems and methods for gathering distributed information to improve routing that uses Anycast for assigning deliveries between a number of geographically-distant points of presence (POPs) are disclosed. The POPs share the same Internet protocol (IP) address. According to Anycast resolution, the Internet aids in assigning a content request initially to a POP. Delivery statistics are gathered from deliveries a the number of POPs and possibly other sources. Where it is determined that Anycast found the wrong POP, the content request is reassigned to another POP.

  • Patent number: 8200958
    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.

    Abstract: A content distribution system for transporting audio or video licenses between content players that use digital rights management (DRM) is disclosed. The content distribution system includes at least a second license repository and an authentication engine. The second license repository receives second information describing a second plurality of content licenses. A first license repository stores a first plurality of content licenses. The first plurality of content licenses enable use of a plurality of content objects with a first content player within confines of DRM. The second license repository is geographically distant from the first license repository. The authentication engine authorizes the second plurality of content licenses of the second license repository. The second plurality of content licenses enable use of the plurality of content objects with the second content player within the confines of DRM.

  • Publication number: 20120066352
    Abstract: A system and method for delivering content objects over the Internet to an end user system with a content delivery network (CDN) is disclosed. Content objects may be dynamically served by loading and/or reconfiguring publishing points upon receipt of an end user request. When an end-user media player requests a content object, the request is assigned to an edge server within a particular POP of the CDN. An optional peer-discovery algorithm may determine a content source for the requested content object within the CDN. The peer-discovery algorithm determines whether the publishing point associated with the requested object is loaded into the edge server. Alternatively, the algorithm queries other edge servers within or remote from the POP to determine whether the request is mapped by other edge servers to a content source using their respective publishing points. The edge server may reconfigure its publishing point toward the content source.
