Problem Statement
Development of cache management interface within open caching architecture to enable pre-positioning, purging, listing and update of content within an open caching system.
Project Description
The SVTA Open Caching Cache Management Interface project seeks to specify content management interface, to facilitate standard-based interoperability between content providers and CDNs on one hand, and open caching systems.
Content management is well-established and understood capability, that was previously addressed by the Streaming Video Technology Alliance as well as the IETF CDN interconnect (CDNi) working group work. This renewed effort will focus on the following objectives:
- Capture up-to-date key use cases and functional requirements for content management within modern content delivery ecosystem
- Identify functional areas where the existing CDNi content management API meets these requirements and where it may be lacking
- Explore additional and/or complementary APIs that are in line with existing content management and processing workflows, to lower adoption barrier and meet the full set of functional requirements
- Specify open caching OpenAPI to facilitate standard-driven and fully interoperable content management operations
- Ensure alignment of the content management interface with the adjacent open caching interfaces and overall open caching architecture
- Facilitate alignment and compatibility with the past and ongoing efforts at the IETF CDNi working group that address content management

SVTA2046: Cache Management Interface
This document outlines the motivation, key use cases, and architecture for a Cache Management Interface to facilitate integration between content providers and content delivery network providers (CDNs) on one side and Open Caching providers on the other.
The document will extend cache management interfaces specified by the Internet Engineering Task Force (IETF) CDN Interconnection (CDNI) to support new cache management use cases and improve interoperability between the parties.
Goals and Objectives
The SVTA Open Caching Cache Management Interface project has the following objectives and goals:
- Capture up-to-date key use cases and functional requirements for content management within modern content delivery ecosystem
- Identify functional areas where the existing CDNi content management API meets these requirements and where it may be lacking
- Explore additional and/or complementary APIs that are in line with existing content management and processing workflows, to lower adoption barrier and meet the full set of functional requirements
- Specify open caching OpenAPI to facilitate standard-driven and fully interoperable content management operations
- Ensure alignment of the content management interface with the adjacent open caching interfaces and overall open caching architecture
- Facilitate alignment and compatibility with the past and ongoing efforts at the IETF CDNi working group that address content management
Project Scope
The SVTA Open Caching Cache Management Interface project will address:
- Use cases, functional requirements, architecture, and data model for the content management interface, including extensions to the CDNi data model
- OpenAPI specifications for the content management interface
- Changes required to adjacent open caching interfaces, including Footprint & Capabilities Interface (FCI) and Configuration Interface
- Updates for the IETF CDNi standards and drafts if required
