    abstract =  {The Content Delivery Networks Interconnection (CDNI) framework 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 CDNI framework is the CDNI Request Routing Footprint \& Capabilities Advertisement interface (FCI). RFC 8008 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 RFC 8008.},
