Ma Status: Standards Track Stream: IETF Date: December 2016 Mailbox: ben.niven-jenkins@nokia.com, rob.murray@nokia.com, mcaulfie@cisco.com, kevin.j.ma@ericsson.com Pages: 66 Characters: 126524 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-cdni-metadata-21.txt URL: https://www.rfc-editor.org/info/rfc8006 DOI: 10.17487/RFC8006 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. This document is a product of the Content Delivery Networks Interconnection 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.
