  1. Use Cases & Requirements IETF#78, Maastricht, NL.

  2. Re-Recap • Registry is the authoritative source for provisioned session establishment data (SED) and related information • Local Data Repository is the data store component of an addressing server that provides resolution responses • Registry is responsible for distributing SED and related information to the Local Data Repositories Registry 1. Provision SED 2. Distribute SED Local Data Repository Local Data Repository

  3. Introduction • The latest I-D revision can be found at: • http://tools.ietf.org/html/draft-ietf-drinks-usecases-requirements-03 • There have been two revisions since Anaheim • The first revision (-02, May) incorporated comments and contributions just before the last IETF • The second revision (-03, May) was a result of the discussions at Anaheim and at the interim F2F meeting

  4. Use Case Categories • Provisioning Mechanisms • Interconnect Schemes • SED Exchange and Discovery Models • SED Record Content • Separation and Facilitation of Data Management • Lookup Keys • Number Portability • Misc.

  5. Snapshot of Use Cases (1/4) • Provisioning • Real-Time • Non-Real-Time Bulk • Multi-request • Interconnect Schemes • Inter-SSP SED • Direct v/s Indirect Peering • Intra-SSP SED • Selective Peering • Delegated Name Server

  6. Snapshot of Use Cases (2/4) • SED Exchange and Discovery Models • Unified LUF/LRF • Using LUF's Domain Name • Using LUF’s Administrative Domain Identifier • Co-existent SED Exchange and Discovery Models • SED Record Content • SED Record Content • Time-To-Live (TTL)

  7. Snapshot of Use Cases (3/4) • Separation and Facilitation of Data Management • Separation of Provisioning Responsibility • Destination Groups • Route Groups • Lookup Keys • Additions and deletions • Carrier-of-Record vs Transit Lookup Key • Multiplicity of Identical Lookup Keys • Lookup Key Destination Group Modification • Lookup Key Carrier-Of-Record vs Transit Modification • Modification of authority

  8. Snapshot of Use Cases (4/4) • Number Portability • Misc • Data Recipient Offer and Accept • Open numbering plans

  9. Data Model Data Recipient ROUTING GROUP SED Record 0..n 0..n 1 0..n 0..n 0..n 1 0..1 DESTINATION GROUP 1 0..n 0..n 0..n Public Identity RN TN Range

  10. Next Steps • Incorporate any additional use cases (e.g., from our discussions today, as the protocol docs mature) • Any contributions? • Discuss and incorporate comments • Otmar provided comments on the list on 7/21 • Any additional review volunteers? • Progress to Last Call? 
