 Content Delivery Network Interconnection (CDNI) Request Routing: CDNI
          Footprint and Capabilities Advertisement using ALTO
              draft-ietf-alto-cdni-request-routing-alto-03

Abstract

   The Content Delivery Networks Interconnection (CDNI) WG is defining a
   set of protocols to inter-connect 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 is the CDNI Request Routing Footprint &
   Capabilities Advertisement interface (FCI) [RFC7336].  [RFC8008] has
   defined precisely the semantics of FCI and provided guidelines on the
   FCI protocol, but the exact protocol is explicitly outside the scope
   of that document.  In this document, we define an FCI protocol using
   the Application-Layer Traffic Optimization (ALTO) protocol.
