  1. CDNI Video Publisher Use cases(draft-ma-cdni-publisher-use-cases-00) Kevin J. Ma kevin.ma@azukisystems.com

  2. Content Publisher Use Cases for Content Delivery Using Multiple CDNs • Content License Enforcement • Temporal Licensing • Device Resolution Licensing • Split Subscription Distribution • Geo-location-based Licensing • HTTP Segment-based Adaptive Bitrate Streaming • Support for highly segmented content • Support for bounded distribution + delivery time for live video • Distribution Policy Management • Specification of content distribution policies • Support for independent refresh of distribution metadata and content

  3. Next Steps: Proposed use cases to be incorporated into cdni-use-cases • “Geo-blocking” section • Expand to include temporal and resolution-based licensing • “Device and Network Technology Extension” section • Expand to detail asymmetric distribution licensing scenarios between CDNs • Expand to include session shifting scenarios between different types of devices available through each CDN • Expand to include multiple subscription scenarios where a given user has different rights through each CDN • “Resiliency” section • Expand to include live streaming failover scenarios • Expand to include live streaming bounded delivery

  4. Next Steps: Proposed enhancements to CDNI requirements • CDNI Metadata Distribution Protocol Requirements • R58: “The CDNI Metadata Distribution protocol MUST allow signaling of content distribution control policies.” • enhance to include whitelists/blacklists of CDNs • CDNI Request Routing Protocol Requirements • R36: “The CDNI Request-Routing protocol SHOULD support an optional mechanism enforcing a limit on the number of successive CDN redirections for a given request.” • enhance to include temporal limits • R38: “The CDNI Request-Routing protocol MAY also allow the Upstream CDN to convey information pointing to CDNI metadata associated with the requested content.” • enhance to include specifying sets of content that should be delegated together for optimized delivery
