Abstract:
1. A method of redirecting content requests among content distribution network peers comprising: establishing, for each content distribution network peer at the each content distribution network peer, a corresponding content distribution table that identifies a plurality of neighbor content distribution network peers, and content contained on each of the plurality of neighbor content distribution network peers; receiving, at a first content distribution network peer, a content request comprising an address of the first content distribution network peer, and an identification of requested content, wherein the first content distribution network peer has the requested content; making a determination that the first content distribution network peer lacks capacity to provide the requested content; referring, based on the determination, to the corresponding content distribution table to find a first neighbor content distribution network peer of the plurality of neighbor content distribution network peers that has the requested content; generating a uniform resource locator including a domain name portion, wherein the domain name portion comprises a domain name associated with the first neighbor content distribution network peer appended to a domain name associated with the first content distribution network peer; and redirecting, by the first content distribution network peer, the content request to the first neighbor content distribution network peer using the uniform resource locator.
