            Content Delivery Network Interconnection (CDNI)
                      Control Interface / Triggers

Abstract

   This document describes the part of the Content Delivery Network
   Interconnection (CDNI) Control interface that allows a CDN to trigger
   activity in an interconnected CDN that is configured to deliver
   content on its behalf.  The upstream CDN can use this mechanism to
   request that the downstream CDN pre-position metadata or content or
   to request that it invalidate or purge metadata or content.  The
   upstream CDN can monitor the status of activity that it has triggered
   in the downstream CDN.
