Content Delivery Networks (CDNs) provide numerous benefits for
cacheable content: reduced delivery cost, improved quality of
experience for End Users, and increased robustness of delivery.  For
these reasons, they are frequently used for large-scale content
delivery.  As a result, existing CDN Providers are scaling up their
infrastructure, and many Network Service Providers (NSPs) are
deploying their own CDNs.  It is generally desirable that a given
content item can be delivered to an End User regardless of that End
User's location or attachment network.  This is the motivation for
interconnecting standalone CDNs so they can interoperate as an open
content delivery infrastructure for the end-to-end delivery of
content from Content Service Providers (CSPs) to End Users.  However,
no standards or open specifications currently exist to facilitate
such CDN Interconnection.

The goal of this document is to outline the problem area of CDN
Interconnection for the IETF CDNI (CDN Interconnection) working
group.  This document is not an Internet Standards Track specification; 
it is published for informational purposes.

This document is a product of the Content Delivery Networks Interconnection Working Group of the IETF.
