Abstract

   The CDNI Metadata interface enables interconnected 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.

Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119 [RFC2119].
