A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Content Delivery Networks Interconnection WG of the IETF. Title : Content Delivery Network Interconnection (CDNI) Footprint Types: Subdivision Code and Footprint Union Authors : Nir B. Sopher Sanjay Mishra Filename : draft-ietf-cdni-additional-footprint-types-07.txt Pages : 12 Date : 2022-12-24 Abstract: 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 and for the Footprint & Capabilities Advertisement interface (FCI) defined in RFC 8008. By defining the footprint union Footprint Type, this document updates RFC 8008, allowing an additive semantic over the narrowing semantics defined in Appendix B of RFC 8008. This document also supplements RFC 9241 with relevant ALTO entity domain types. The defined Footprint Types are derived from requirements raised by Open Caching but are also applicable to CDNI use cases in general.
