Abstract

   The Open Caching working group of the Streaming Video Alliance is
   focused on the delegation of video delivery requests 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).

Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",

   document are to be interpreted as described in RFC 2119 [RFC2119].

1.  Introduction

   This document defines objects needed for Open Caching request
   routing.  For that purpose it extends CDNI metadata [RFC8006] and
   CDNI Footprint and Capabilities [RFC8008].  For consistency, this
   document follows the CDNI notation of uCDN (the commercial CDN) and
   dCDN (the ISP caching layer).

   This document also registers CDNI Payload Types [RFC7736] for the
   defined objects:

   o  Redirect Target Capability (for dCDN advertising redirect target
      address)

   o  Fallback Target Metadata (for uCDN configuring fallback target
      address)
