 Content Delivery Network Interconnection (CDNI) Request Routing: CDNI
          Footprint and Capabilities Advertisement using ALTO
              draft-ietf-alto-cdni-request-routing-alto-14

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.  This document defines an FCI
   protocol using the Application-Layer Traffic Optimization (ALTO)
   protocol, following the guidelines defined in [RFC8008].

Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
   "OPTIONAL" in this document are to be interpreted as described in BCP
   14 [RFC2119][RFC8174] when, and only when, they appear in all
   capitals, as shown here.
