This document provides an overview of the various components necessary to interconnect CDNs, expanding on the problem statement and use cases introduced in [RFC6770] and [RFC6707]. It describes the necessary interfaces and mechanisms in general terms and outlines how they fit together to form a complete system for CDN Interconnection. Detailed specifications are left to other documents. This document makes extensive use of message flow examples to illustrate the operation of interconnected CDNs, but these examples should be considered illustrative rather than prescriptive.

    Framework for Content Distribution Network Interconnection (CDNI)


   This document presents a framework for Content Distribution Network    Interconnection (CDNI).  The purpose of the framework is to provide    an overall picture of the problem space of CDNI and to describe the    relationships among the various components necessary to interconnect    CDNs.  CDNI requires the specification of interfaces and mechanisms    to address issues such as request routing, distribution metadata    exchange, and logging information exchange across CDNs.  The intent    of this document is to outline what each interface needs to    accomplish and to describe how these interfaces and mechanisms fit    together, while leaving their detailed specification to other    documents.  This document, in combination with RFC 6707, obsoletes    RFC 3466.
