  1. Optical Networking andConverged NetworksImpact and Trends in Standardisation Adrian Farrel adrian@olddog.co.uk

  2. Why Bother Standardising? • Standardisation is principally for interoperability • Conformance to standards can help in procurement • Standards reduce development costs • Standards reduce operational costs • But • Optical interoperability has been pretty rare • Changing slightly with ROADMs • Will it change with converging network technologies? • Maybe OTN and flexible wavelength grids interworking? • May be interesting at the optical edge

  3. Research and Standardisation • Standards describe what is built and deployed • Research has a difficult role in standardisation • Not enough to document “great ideas” • Must engage the commercial community • Cannot take complete ideas for “rubber stamp” • Must engage the standardisation community • Research needs to be cutting edge • May be too early for standardisation • Optical technologies supporting converged networks are an interesting opening • Many companies want to help the research • Standards bodies are open to new ideas in this area

  4. What Standards Exist? • Optical physical layer mainly done (thanks ITU-T) • Optical physical interworking in hand (thanks OIF) • Core optical control planes all done • GMPLS etc. (thanks IETF) • Core integrated network planning all done • PCE etc. (thanks IETF) • But… • New optical developments? • Converged networks?

  5. What is Coming Next? • For optical networks to enable converged networking we need a fully-functional control plane • IETF about to publish GMPLS for OTN • IETF working on GMPLS for flexible grid • For converged networking we need operational and management components • IETF working on stateful and active PCE • IETF looking at ways to integrate PCE and SDN into the wider converged network ecosphere • Interface to the Routing System (I2RS) • Application-Based network Operation (ABNO)

  6. How The IETF Works • The IETF is the standards body for the Internet • Anyone and everyone can participate • All work on open email lists • Ideas are written up as Internet-Drafts • When there is community consensus they are published as RFCs • At the network and lower layers it works best when driven by operator demands and vendor implementation • A healthy balance of academic and research input • Don’t forget the Internet Research Task Force (IRTF)

  7. IDEALIST and Standardisation • IDEALIST is an FP7 project working on multi-layer networks built on flexible grid lambdas • Physical layer standardisation is complete • ITU-T G.694.1 • The project is helping to standardise • GMPLS control plane for flexi-grid (IETF) • Multi-layer planning and provisioning (IETF) • The participation of equipment vendors and operators is key • This is standardisation for a purpose • It is not a “pure research” project
