Abstract Abstract
This document presents a framework for Content Distribution Network This document presents a framework for Content Distribution Network
Interconnection (CDNI). The purpose of the framework is to provide Interconnection (CDNI). The purpose of the framework is to provide
an overall picture of the problem space of CDNI and to describe the an overall picture of the problem space of CDNI and to describe the
relationships among the various components necessary to interconnect relationships among the various components necessary to interconnect
CDNs. CDN Interconnection requires the specification of interfaces CDNs. CDN Interconnection requires the specification of interfaces
and mechanisms to address issues such as request routing, and mechanisms to address issues such as request routing,
distribution metadata exchange, and logging information exchange distribution metadata exchange, and logging information exchange
