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 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.

Content delivery network encryption

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.
