 Content Delivery Network Interconnection (CDNI) Request Routing: CDNI
          Footprint and Capabilities Advertisement using ALTO
              draft-ietf-alto-cdni-request-routing-alto-06

Abstract

   The Content Delivery Networks Interconnection (CDNI) framework
   [RFC6707] defines a set of protocols to interconnect CDNs, to achieve
   multiple goals such as extending the reach of a given CDN to areas
   that are not covered by that particular CDN.  One component that is
   needed to achieve the goal of CDNI described in [RFC7336] is the CDNI
   Request Routing Footprint & Capabilities Advertisement interface
   (FCI).  [RFC8008] defines precisely the semantics of FCI and provides
   guidelines on the FCI protocol, but the exact protocol is explicitly
   outside the scope of that document.  In this document, we follow the
   guidelines to define an FCI protocol using the Application-Layer
   Traffic Optimization (ALTO) protocol.
