Abstract

   The Content Delivery Networks Interconnection (CDNI) metadata
   interface enables interconnected Content Delivery Networks (CDNs) to
   exchange content distribution metadata in order to enable content
   acquisition and delivery.  The CDNI metadata associated with a piece
   of content provides a downstream CDN with sufficient information for
   the downstream CDN to service content requests on behalf of an
   upstream CDN.  This document describes both a base set of CDNI
   metadata and the protocol for exchanging that metadata.
