2. Standardisation Activities on Felxigrid – ECOC 2013 – London, September 2013 Why standardise?  Standardisation makes things work better Interoperability  Standardisation means you know what you are buying The product fulfils the publically-available specification  Standardisation means you know what to make The requirements and specification have been thought through and published 1

3. Standardisation Activities on Felxigrid – ECOC 2013 – London, September 2013 Why standardise?  Plug-and-play compatibility is largely a myth in optical networks Every vendor has optical secret source Some potential at the optical edge  Potential of common control plane across multiple vendors  Benefits to component manufacturers Hardware and software › Comoditisation › Streamlined development costs › Pooled learning curve and debugging  Operational, training, and research advantages Common elements across platforms and networks Staff skills are portable 2

4. Standardisation Activities on Felxigrid – ECOC 2013 – London, September 2013 Standardisation outcomes for FP7 Projects  Increasing demand for “standardisation” as an outcome of EC-funded projects  Why does the Commission care? It is a measurable outcome › How many standards? It provides external verification › The commercial world has validated the project work It is a valuable shared product › The standards disseminate the project work › It shows thought-leadership from within Europe  Why should the participants care? It is a way of getting (free) input to the project …and all the above 3

5. Standardisation Activities on Felxigrid – ECOC 2013 – London, September 2013 Standardisation Mechanisms and Paradigms  Standardisation is a cooperative process Don’t expect a rubber stamp on your private work Do expect critical review and modification  Standardisation is not a rapid process Everything is done in the right order and with the right amount of review  Don’t under-estimate the value of implementation “Running code”  Take your work to the right standards body Seek out the experts and get critical review Don’t fuel “turf wars”  Look for open standards processes Open for participation Open work practices Freely available output 4

6. Standardisation Activities on Felxigrid – ECOC 2013 – London, September 2013 Standardisation in IDEALIST  IDEALIST aims at developing data and control plane solutions based on elastic networks enabling adaptive network and service interworking Includes (is built on) use of flexigridstart Project proposal 2011 Project November 2012  Standardisation from day one Often left to the end of the project › Very little chance of successful completion › Leads to rushed work and a demand for a “rubber stamp” › Causes the project work to carry on, sometimes for years IDEALIST puts standardisation as a key and early outcome › Stated in the project proposal › An immediate focus Work actually started as soon as the proposal was put together 5

7. Standardisation Activities on Felxigrid – ECOC 2013 – London, September 2013 Flexigrid Data Plane Standardisation  Data plane Main work already completed before project start  ITU-T Recommendation G.671 "Transmission characteristics of optical components and subsystems“ (2009)  ITU-T Recommendation G.694.1 (revision 2) "Spectral grids for WDM applications: DWDM frequency grid" (February 2012)  ITU-T Recommendation G.694.2 "Spectral grids for WDM applications: CWDM wavelength grid“ (December 2003)  Key formulae Frequency (THz) = 193.1 THz + n * frequency granularity (THz) › Frequency granularity for the flexible grid is 0.00625 THz Slot Width (GHz) = 12.5 GHz * m 6
