               CDNI Control Triggers Interface Extensions
            draft-finkelman-cdni-triggers-sva-extensions-01

Abstract

   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 CI/T interface
   are derived from requirements raised by 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].
