                Request Routing Redirection Interface for              Content Delivery Network (CDN) Interconnection

Abstract

   The Request Routing interface comprises (1) the asynchronous    advertisement of footprint and capabilities by a downstream Content    Delivery Network (CDN) that allows an upstream CDN to decide whether    to redirect particular user requests to that downstream CDN; and (2)    the synchronous operation of an upstream CDN requesting whether a    downstream CDN is prepared to accept a user request and of a    downstream CDN responding with how to actually redirect the user    request.  This document describes an interface for the latter part,    i.e., the CDNI Request Routing Redirection interface.
