Internet Engineering Task Force (IETF) R. Murray Request for Comments: 8007 B. Niven-Jenkins Category: Standards Track Nokia ISSN: 2070-1721 December 2016 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. Status of This Memo This is an Internet Standards Track document.
