CDNI SVA Request Routing Extensions
draft-finkelman-cdni-rr-sva-extensions-01
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).

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)
