CDNI Request Routing Extensions
draft-sopher-cdni-footprint-types-extensions-01
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). This document supplements to
the CDNI Metadata Footprint Types defined in RFC 8006. The Footprint
Types defined in this document can be used for Footprint objects as
part of the Footprint & Capabilities Advertisement interface (FCI)
defined in RFC 8008. The defined Footprint Types are derived from
requirements raised by Open Caching but are also applicable to CDNI
use cases in general.

1. Introduction
The Streaming Video Alliance [SVA] is a global association that works
to solve streaming video challenges in an effort to improve end-user
experience and adoption. The Open Caching Working Group [OCWG] of
the Streaming Video Alliance [SVA] is focused on the delegation of
video delivery requests from commerical CDNs to a caching layer at
the ISP's network. Open Caching architecture 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 Open Caching
Request Routing Specification [OC-RR] defines the Request Routing
process and the interfaces that are required for its provisioning.
This document defines and registers CDNI Footprint and Capabilities
objects[RFC8008] that are required for Open Caching Request Routing.
