                  CDNI extensions for HTTPS delegation
            draft-fieau-cdni-interfaces-https-delegation-04

Abstract

   The delivery of content over HTTPS involving multiple CDNs raises
   credential management issues.  This document proposes extensions in
   CDNI Control and Metadata interfaces to setup HTTPS delegation from
   an Upstream CDN (uCDN) to a Downstream CDN (dCDN).

1.  Introduction

   Content delivery over HTTPS using one or more CDNs along the path
   requires credential management.  This specifically applies when an
   entity delegates delivery of encrypted content to another trusted
   entity.

   Several delegation methods are currently proposed within different
   IETF working groups (refer to [I-D.fieau-cdni-https-delegation] for
   an overview of delegation works ongoing at the IETF).  They specify
   different methods for provisioning HTTPS delivery credentials.

   This document extends the CDNI Metadata interface to setup HTTPS
   delegation between an upstream CDN (uCDN) and downstream CDN (dCDN).
   Furthermore, it includes a proposal of IANA registry to enable the
   adding of new methods in the future.

   Section 2 is about terminology used in this document.  Section 3
   presents delegation methods specified at the IETF.  Section 4
   introduces delegation metadata in CDNI.  Section 5 addresses the
   delegation methods objects.  Section 6 describes simple data types.
