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 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.
