CDNI Control Interface / Triggers
draft-ietf-cdni-control-triggers-12
Abstract
This document describes the part of the CDN Interconnection 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-positions metadata or content, or that it invalidates or
purges metadata or content. The upstream CDN can monitor the status
of activity that it has triggered in the downstream CDN.
Requirements Language

"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC 2119 [RFC2119].
