Technical Summary
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.
Working Group Summary
The WG process was not contentious.
Document Quality
There is one known implementation in progress. As with all ALTO extensions,
there are experiments, but still uncertainty about whether the base protocol
will see wide deployment. In particular, the CDNI use case is perceived to be
much more promising than the initial target, peer-to-peer networks.
