Internet Engineering Task Force (IETF) B. Niven-Jenkins Request for Comments: 8006 R. Murray Category: Standards Track Nokia ISSN: 2070-1721 M. Caulfield Cisco Systems K. Ma Ericsson December 2016 Content Delivery Network Interconnection (CDNI) Metadata Abstract The Content Delivery Network Interconnection (CDNI) Metadata interface enables interconnected Content Delivery Networks (CDNs) to exchange content distribution metadata in order to enable content acquisition and delivery. The CDNI Metadata associated with a piece of content provides a downstream CDN with sufficient information for the downstream CDN to service content requests on behalf of an upstream CDN. This document describes both a base set of CDNI Metadata and the protocol for exchanging that metadata. Status of This Memo This is an Internet Standards Track document. This document is a product of the Internet Engineering Task Force (IETF). It represents the consensus of the IETF community. It has received public review and has been approved for publication by the Internet Engineering Steering Group (IESG). Further information on Internet Standards is available in Section 2 of RFC 7841.
