3. Global networks are creatingextremely important new challenges Credit: MONET Group at UIUC Science Issues We cannot currently understand or predict the behavior of complex,large-scale networks Innovation Issues Substantial barriers toat-scale experimentation with new architectures, services, and technologies Society Issues We increasingly rely on the Internet but are unsure we can trust its security, privacy or resilience

4. GENI: Infrastructure for Experimentation GENI provides compute resources that can be connected in experimenter specified Layer 2 topologies.

6. Multiple GENI Experiments run Concurrently Resources can be shared between slices Experiments live in isolated “slices”

7. GENI is “Deeply Programmable” I install software I want throughout my network slice (into routers, switches, …) or control switches using OpenFlow Experimenters can set up custom topologies, protocols and switching of flows

8. GENI Compute Resources GENI Wireless compute nodes GENI Racks Existing Testbeds (e.g. Emulab)

9. GENI Networking Resources National Research Backbones (e.g. Internet2) Networking within a Rack Regional Networks (e.g. CENIC) WiMAX Base Stations

11. A bright idea “I have a great idea.” “That will never work.”

12. Let’s try it out! My new architecture worked great in the lab, so now I’m going to try a larger experiment for a few months. He uses a modest slice of GENI, sharing its infrastructure with many other concurrent experiments.

13. It turns into a really good idea This service looks very useful His slice of GENI keeps growing, but GENI is still running many other concurrent experiments.

14. Attracts real users “Looks like an app to me.” “It’s my very own GENI slice.”

15. “Boy did I learn a lot!” “What a cool service.” (I wonder how it works.) “I always said it was a great idea.” (But way too conservative.)

16. ?? If you have a great idea, check out theNSF CISE research programs for current opportunities.

17. Moral of this story GENI is meant to enable . . . At-scale experiments Internet-incompatible experiments Both repeatable and “in the wild” experiments ‘Opt in’ for real users Instrumentation and measurement tools GENI creates a huge opportunity for ambitious research!
