Title: Optical Networking and Converged Networks Impact and Trends in Standardisation


1
Optical Networking andConverged NetworksImpact
and Trends in Standardisation
  • Adrian Farrel

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
  • Dont 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
