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.
