A method of servicing content requests in a CDN may include receiving a request for content from a first client device, identifying content associated with the content request, identifying a second client device that stores the content, identifying a CDN storage location that also stores the content, determining whether the second client device is authorized to source the content to the first client device, and selecting a source for the content. The source for the content may be selected from the storage location associated with the CDN and the second client device. The source for the content may be selected based on one or more CDN policies. The method may also include initiating a transfer of the at least a portion of the content from the second client device to the first client device if the second client device is selected as the source for the content.

Origin request with peer fulfillment

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.

Content delivery network stream server vignette distribution

A method for transferring content across a content delivery network (CDN) may include receiving a notification of a request. The request may include a client identifier and a content identifier. The method may also include accessing one or more global policies applicable to the request. The method may additionally include determining, using the one or more global policies, that a client is eligible to receive content associated with the content identifier from another client; identifying, using the one or more global policies and the content identifier, one or more authorized transfers of at least a portion of the content; identifying one or more eligible clients that are associated with the one or more authorized transfers; and sending a set of client identifiers that are associated with the one or more eligible clients.

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 serving content objects by loading and/or reconfiguring publishing points upon receipt of an end user request. When a content object is requested by an end user media player, the request is assigned to an edge server within a particular POP of the CDN. An optional peer-discovery algorithm is used to determine a content source for the requested content object within the CDN. The peer-discovery algorithm first determines whether the publishing point associated with the requested content object is loaded into the edge server. Alternatively, the peer-discovery algorithm queries other edge servers within or remote from the particular POP to determine whether the request for content object is mapped by other edge servers to a content source using their respective publishing points. Once the content source for the requested content object is determined, the edge server reconfigures its publishing point toward the content source. Ultimately, the content object is streamed to the end user media player. Management of the publishing points avoids performance degradations on the edge server in some embodiments.

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.
