CDNI Control Triggers Interface Extensions
draft-ietf-cdni-triggers-extensions-08
Abstract
Open Caching architecture is a use case of Content Delivery Network
Interconnection (CDNI) in which the commercial Content Delivery
Network (CDN) is the upstream CDN (uCDN) and the ISP caching layer
serves as the downstream CDN (dCDN). This document defines
extensions to the Content Delivery Network Interconnection (CDNI)
Control Interface/Triggers defined in RFC 8007. These extensions are
derived from requirements raised by Open Caching architecture but are
also applicable to CDNI use cases in general.
Requirements Language
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC 2119 [RFC2119].
