What is GENI? GENI will be a full-scale programmable facility for research into the future internet Focus: whatever experiments researchers need to create, test and evaluate the high impact new ideas Clean-slate approach, Opportunity for:  Unencumbered starting points  Novel architectures and big picture  Strong coupling with technology drivers of futures Mobile wireless Novel optical substrate capability

GENI Design: Building Blocks Three major components  Physical network ‘substrate’ expandable collection of building block components federate  Software control & management framework knits building blocks together into a coherent facility embeds ‘slices’ in the physical substrate  Operational control (GENI management) is distinct from experiment control Components  design, build, operate, iterate in modules, throughout lifecycle

GENI Design – Fully Programmable Routing/Switching Nodes  Clean-slate for architecture and protocol research Slicing/Virtualization of Physical “Substrate”  Concurrent exploration of a broad range of experimental networks (including edge resources such as clusters)  Guaranteed resources, interference free will be available Instrumented resources  Fully Measure experimental behavior Interconnect GENI and the commodity internet Users and applications can “opt-in” to GENI  There will be access to both “customers” for novel long-lived services and to “populations” of real users Flexible and Phased Design  To support new technology introduction throughout GENI lifetime  See A Tale of Two GENI’s on GENI.net site!

GENI M&C (“GMC”) Linux OS Control Module Processor Chassis with appropriate size/performance (sensor GW, mobile node, ad hoc router, AP, BTS…) End-user Wireless Devices (commercial sensors, phones, PDA’s, laptops) With GENI opt-in? Linux OS w/ GENI control Wireless GENI Network Elements All components also available as wireless kits

Some Ongoing Discussions How do we do systems engineering and planning for fast evolving radio / wireless substrates? How much can radio / wireless be virtualized? GENI performance in general?  How much scale-down is acceptable per element?  How can a project/experiment buy better performance fidelity, and how much? Missing key radio (and optical, other physical) Areas?  Optical access networks?  Wireless over fiber?  Quantum Cryptography?

GENI Success Scenarios (many alternatives) Internet evolution influenced by clean-slate approach Architectures achieve fundamental progress in challenge areas such as security New services and applications enabled Alternate Internet architecture emerges  Virtualization becomes the norm with plurality of architectures  Single new architecture from the research enabled by GENI emerges and dominates  Alternative infrastructure becomes the mainstream over time Many other payoffs, including unanticipated and high risk
