SVTA Open Caching CDNi
IETF
The Open Caching Working Group has been engaged with the CDNi efforts of the IETF for quite some time. The primary objective was to ensure that CDNi specifications reflected Open Caching API-based approaches to CDN functionality and management. The following IETF documents and RFCs reflect the collaboration between the Streaming Video Alliance and the IETF on caching:
CDNI Capacity Capability Advertisement Extensions
Open Caching architecture is a use case of Content Delivery Networks 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 supplements to the CDNI Capability Objects defined in RFC 8008 the defined capability objects structure and interface for advertisements and management of a downstream CDN capacity.
CDNI Metadata Model Extensions
The Content Delivery Network Interconnection (CDNI) Metadata interface enables interconnected Content Delivery Networks (CDNs) to exchange content distribution metadata in order to enable content acquisition and delivery. To facilitate a wider set of use cases such as Open Caching, this document describes extensions to the CDNI Metadata object model and its associated Capabilities model as documented in “CDNI Metadata” RFC8006 and “CDNI Request Routing: Footprint and Capabilities Semantics” RFC8008 .
This document is a reflection of the content in the Streaming Video Alliance specification titled “SVA Configuration Interface: Part 2 Extensions to CDNI Metadata Object Model”.
Content Delivery Network Interconnection (CDNI) Control Interface / Triggers 2nd Edition
This document obsoletes RFC8007. 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.
Content Delivery Network Interconnection (CDNI) Footprint Types: Subdivision Code and Union
Open Caching architecture is a use case of Content Delivery Networks 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 supplements the CDNI Metadata Footprint Types defined in RFC 8006. The Footprint Types defined in this document can be used for Footprint objects as part of the Metadata interface (MI) defined in RFC 8006 or the Footprint & Capabilities Advertisement interface (FCI) defined in RFC 8008. The defined Footprint Types are derived from requirements raised by Open Caching but are also applicable to CDNI use cases in general
Content Delivery Network Interconnection (CDNI) Request Routing Extensions (RFC 8804)
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 CDNI Metadata Interface (MI) and the Footprint & Capabilities Advertisement interface (FCI). These extensions are derived from requirements raised by Open Caching but are also applicable to CDNI use cases in general.
