  3. Non-Goals / Out of Scope • New session, transport or network protocols • Interfaces/protocols between • CSP & CDN • Content ingestion • CDN & CDN • Content acquisition • CDN & End User • New delivery protocols • Content preparation • Encoding/Transcoding • DRM • Apps consuming CDNI logs • Internal CDN protocols • Individual CDN scalability • Algorithms for • Intra-CDN & Inter-CDN request routing • Caching

  4. Priorities • Industry needs a targeted, deployable solution • 18-24 month timeframe • Initial charter scope • Minimum scope for interworking CDNs to allow operators to offer a basic operational service • Do not want to boil the ocean • Enhanced scope • Extra stuff • Would require re-chartering • Reuse not reinvention • Reuse existing session, transport & application protocols (without changes) • Reuse existing schema languages (without changes) • We expect to just define the schemas & associated semantics to exchange required information over existing application protocol(s)

  5. Standards Gap • IETF CDI WG (Concluded) • 3GPP • ISO MPEG • ATIS IIF / CoD • CableLabs • ETSI MCD / TISPAN • ITU-T SG13 • OIPF • TV-Anytime • SNIA • IRTF P2PRG • OCEAN • Eurescomm P1955 ATIS • Has use cases for CDNI • Do not want to define protocols • Would like to reuse CDNI • CDNI drafts cover their needs • 1 extra requirement • ETSI • Similar to ATIS Only those in bold are working on CDNI related architectures The ones working on Metadata do not cover “distribution metadata”
