Internet Engineering Task Force (IETF) K. Leung, Ed. Request for Comments: 7337 Cisco Category: Informational Y. Lee, Ed. ISSN: 2070-1721 Comcast August 2014 Content Distribution Network Interconnection (CDNI) Requirements Abstract Content delivery is frequently provided by specifically architected and provisioned Content Delivery Networks (CDNs). As a result of significant growth in content delivered over IP networks, existing CDN providers are scaling up their infrastructure. Many Network Service Providers (NSPs) and Enterprise Service Providers (ESPs) are also deploying their own CDNs. To deliver contents from the Content Service Provider (CSP) to end users, the contents may traverse across multiple CDNs. This creates a need for interconnecting (previously) standalone CDNs so that they can collectively act as a single delivery platform from the CSP to the end users. The goal of the present document is to outline the requirements for the solution and interfaces to be specified by the CDNI working group.

Introduction The volume of video and multimedia content delivered over the Internet is rapidly increasing and expected to continue doing so in the future. In the face of this growth, 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, CDNs are frequently used for large-scale content delivery. As a result of the significant growth in content delivered over IP networks, existing CDN providers are scaling up their infrastructure and many NSPs and ESPs are deploying their own CDNs. Subject to the policy of the Content Service Provider (CSP), it is generally desirable that a given item Leung & Lee Informational [Page 2] RFC 7337 CDNI Requirements August 2014Show full document text
