Content Delivery Network Interconnection Request Routing Extensions
RFC 8804, “Content Delivery Network Interconnection Request Routing Extensions”, is a Proposed Standard document published in September 2020 by O. Finkelman, S. Mishra. The canonical text is published by the RFC Editor.
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 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.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
