Abstract
A method of redirecting content requests among content distribution network peers. In operation, a client sends a request for content to a content distribution network (CDN). When this CDN does not currently have the capacity to deliver the content, the CDN refers to one or more content distribution tables to see if the neighbor peers are able to provide this content. The content distribution table is populated at the time of distribution of the content. When the neighbor peer has this content, the request is redirected to the neighbor peer. In redirecting request, an address of the neighbor peer is appending to the previous address such that each peer receiving the request knows where the request came from and where it has been previously.
