The IESG has received a request from the Content Delivery Networks Interconnection WG (cdni) to consider the following document: - 'Content Distribution Network Interconnection (CDNI) Problem Statement' <draft-ietf-cdni-problem-statement-06.txt> as Informational RFC The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2012-06-06. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract Content Delivery Networks (CDNs) provide numerous benefits: reduced delivery cost for cacheable content, 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. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-cdni-problem-statement/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-cdni-problem-statement/ballot/ No IPR declarations have been submitted directly on this I-D.
