Transcript

  • 1. Steve Joiner, Technical Committee Chair John McDonough, Member OIF Board of Directors www.oiforum.com Optical Internetworking Forum
  • 2. What is the OIF?
    • Why the OIF?
    • Organization of Working Groups
    • Possible Interaction OIF / ITU-T
    • Summary
  • 3. What is OIF?
    • Launched in April of 1998
    • Open forum: 340+ members including many of the world’s leading carriers and vendors
    • The only industry group bringing together professionals from the packet and circuit worlds
    • Addresses key issues in a timely fashion that are not being addressed elsewhere
    • Mission: To foster the development and deployment of interoperable products and services for data switching and routing using optical networking technologies
  • 4. Output from OIF
    • Develop implementation agreements among its members
      • Standalone documents representing broad agreement among members
    • OIF implementation agreements assure customers of consistent functionality and interoperability
    • Provides input into existing standards bodies and influences the development of standards

  • 7. OIF and Standards Bodies
    • OIF submissions perform two functions:

      • Provide informational documents to the target standards group
    • Established Liaisons With:
      • ANSI T1
      • IETF
      • ATM Forum

      • Benefits to system vendors and technology vendors
      • Interface definitions lead to physical module standardization, thus lower costs
      • Serializer/Deserializer-Framer Interfaces (SFIs)
      • System Physical Interfaces (SPIs)
      • 10G and 40 G
    • Interfaces between network elements
      • Very Short Reach Interfaces (VSR)
      • Parallel optics solutions for low cost 10 G interfaces
    Link Layer (Packet and Cell based Protocols) Rest of the System SONET/SDH Framer PHY Layer SERDES E/O Transceiver Transmission Media SPI SFI
  • 10. PLL Agreements

      • VSR-1, 12 fiber x 1.25Gb/s 850nm (<300m)
      • VSR-2, Serial 1310nm (<600m)
      • VSR-3, 4 fiber x 2.5Gb/s 850nm (<300m)
      • VSR-4, Serial 850nm (<300m)

  • 17. Objective of OIF / ITU-T interaction
    • The OIF does not want to duplicate other work.
    • Our membership is substantially different in makeup to the ITU membership
    • The OIF will debate in its forum the pros/cons of different approaches.
    • Frequent and close communication will insure that the diversity of objectives and solutions will be heard and lead to the best solutions.
  • 18. OIF Summary
    • Brings together professionals from the data and circuit worlds
    • Addressing key issues important to carriers and vendors
    • Nine technical documents ratified as Implementation Agreements
    • Optical module interface standards will allow industry to gain needed economies of scale
    • Future work: (NNI) Network to Network Interface; richer functionality UNI 2.0; billing for UNI.
