                    CDNI Request Routing Extensions
             draft-ietf-cdni-request-routing-extensions-08

Abstract

   Open Caching architecture is a use case of Content Delivery Networks
   Interconnection (CDNI) in which the commercial Content Delivery
   Network (CDN) is the upstream CDN (uCDN) and the ISP caching layer
   serves as the downstream CDN (dCDN).  The extensions specified in
   this document to the CDNI Metadata Interface (MI) and the Footprint
   and Capabilities Interface (FCI) are derived from requirements raised
   by Open Caching but are also applicable to CDNI use cases in general.
