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.
