               CDNI Control Triggers Interface Extensions
                 draft-ietf-cdni-triggers-extensions-01

Abstract

   This document updates RFC 8007 to include generic extensions and more
   granular content matching options, required by the Open Caching
   architecture.  The Open Caching working group of the Streaming Video
   Alliance is focused on the delegation of video delivery request from
   commercial CDNs to a caching layer at the ISP.  In that aspect, Open
   Caching is a specific use case of CDNI, where the commercial CDN is
   the upstream CDN (uCDN) and the ISP caching layer is the downstream
   CDN (dCDN).  The extensions specified in this document to the CDNI
   Control Interface / Triggers are derived from requirements of Open
   Caching but are applicable to CDNI use cases in general.

Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119 [RFC2119].
