The Content Delivery Networks Interconnection (CDNI) framework in RFC
6707 defines a set of protocols to interconnect CDNs to achieve
multiple goals, including extending the reach of a given CDN. A CDNI
Request Routing Footprint & Capabilities Advertisement interface
(FCI) is needed to achieve the goals of a CDNI. RFC 8008 defines the
FCI semantics and provides guidelines on the FCI protocol, but the
exact protocol is not specified. This document defines a new
Application-Layer Traffic Optimization (ALTO) service, called "CDNI
Advertisement Service", that provides an implementation of the FCI,
following the guidelines defined in RFC 8008.
This document is a product of the Application-Layer Traffic Optimization
Working Group of the IETF.
This is now a Proposed Standard.
STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements. Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the
standardization state and status of this protocol. Distribution of this
memo is unlimited.
