1. How to stimulate use and populate facilities? Hagen Woesner Project OFELIA

2. 5 minute view on a non-trivial problemPopulation and use is necessary but not sufficient. How to stimulate use and populate facilities? Have a facility Provide low entry barriers to it Give incentives for extensions How to turn a populated facility into a sustainable one? Provide advantages to community Provide advantages to individual testbed providers 13/12/2010 2

3. 1. Have a facility Facilities (here: testbeds) havetobe Attractive. Publishedresultsthateveryonecanrepeaton thefacilitygivecredibilitytoyourresearch.

7. Plus some protocol that transports the frames over ssl/tcp

8. Allows flexible control down to individual flows

9. Is protocol agnostic, programmable, scalable

10. Allows deployment & test of new controllers & control apps

12. non-IP experiments such as content-based addressing

13. Multi-domain OpenFlow requires controller/controller communicationAdvances beyond state of the art. Priorities w.r.t. scientific challenges. Processing

15. 5 OpenFlow-enabed islands at academic institutions:

16. Berlin (TUB) – partial replacement of existing campus network with OF-switches

17. Gent (IBBT) – central hub, large-scale emulation

18. Zürich (ETH) – connection to OneLab and GpENI

19. Barcelona (i2CAT) – experience with facility projects (IaaS, DRAGON)

20. Essex (UEssex) – national hub for UK optical community; L2 (Extreme) switches, FPGA testbed

21. NEC provides homogeneous L2 hardware platform (OF-enabled Ethernet switches)

22. ADVA as major vendor of optical access and data center equipment

23. Different external vendors(Juniper, Extreme)

24. Explore extensions of OpenFlow towards wireless and optical transmissionAdditional partners and European manufacturers will be involved through Open Calls

26. Phase ii: Connect islands and extend OF experimentation to wireless and optics

28. Standard communication channels (mailing lists, IEEE ComMag)

29. Industry fora: Metro Ethernet Forum, Optical Internetworking Forum, Open Grid ForumExplain how an early operative prototype will be gradually expanded and who will do it, including budgetary issues Gradual expansion of early operative facilty Promotion/ implementation of open calls i: Create islands on L2 ii: Connect islandsandextendtowireless/optics iii: Ressource assignmentautomizationandconnectiontootherfacilities M6 M18
