Abstract:
A system and method for accelerating web page delivery is disclosed in one embodiment. Web content requests are made to an edge server of a first point of presence (POP) of a content delivery network (CDN). The web content has embedded resource links. The first POP can rewrite the embedded resource links to route requests for the embedded resource links to any POP in the CDN or even the origin server. In some embodiments, the first POP can decide if the first POP and/or another POP referenced in a rewritten embedded resource link should cache and/or accelerate the resource referenced in the embedded resource link.
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.
Abstract:
Techniques for delivering content to an end user device are disclosed. A policy server performs an ingest process in which multiple versions of a content object are created. The multiple versions of the content object are associated with a single network identifier which can be distributed to publishers of the content object. When the content object is requested using the single network identifier, the policy server determines a preferred version and delivery orchestration scheme from among the multiple versions for delivery to an end user device based on several criteria. The policy server may thereafter orchestrate delivery of the preferred version of the content object to the end user device. The single network identifier may be associated with an edge location in a content delivery network (CDN) and the policy server may orchestrate delivery in cooperation with servers at the CDN edge location.
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. The system and method allow for dynamically storing and distributing a portion of content streams. When a content object is requested by an end user media player, the request is assigned to an edge server within the CDN. Characteristics of the content object are used to determine the portion of the content object where the portion is less than all of the requested content. The portion of content object is then retrieved from the content and is stored within the CDN. The portion of requested content is streamed to the end user media player. Ultimately, the whole content is streamed to the end user media player if the remainder of content is requested by the end user media player.
Abstract:
A method, apparatus and system for data transfer is disclosed. For example, settings from multiple entities arranged in a multi-tier control plane are used to set data transfer policies. The policies are use to govern data transfers such as between end users or from an origin server.
Abstract:
According to the invention, a content delivery network (CDN) for delivering content objects over the Internet is disclosed. The CDN includes a point of presence (POP), a content object request interface, and a routing function. At least one POP is coupled to a plurality of full-route networks. The content object request interface receives requests for content objects for delivery to a number of end users using a plurality of terminal networks. The routing function that routes content objects in at least two modes, where a first mode routes content objects based upon a first route path chosen based upon delivery efficiency, and a second mode routes at least some content objects using a second route path when at least of a portion of the first route path reaches a level of use. The first and second route paths egress to different full-route networks.

Abstract:
Techniques for generating automated tags for a video file are described. The method includes receiving one or more manually generated tags associated with a video file, based at least in part on the one or more manually entered tags, determining a preliminary category for the video file, and based on the preliminary category, generating a targeted transcript of the video file, wherein the targeted transcript includes a plurality of words. The method further includes generating an ontology of the plurality of words based on the targeted transcript, ranking the plurality of words in the ontology based on a plurality of scoring factors, and based on the ranking of the plurality of words, generating one or more automated tags associated with the video file.
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.
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.
