3. GENI is meant to enable… • Trials of new architectures, which may or may notbe compatible with today’s Internet • Long-running, realistic experiments with enough instrumentation to provide real insights and data • ‘Opt in’ for real users into long-running experiments • Large-scale growth for successful experiments, so good ideas can be shaken down at scale • GENI itself is not an experiment - it is a stable facility on which experiments are run

4. Our plan for building GENI • Start with a clear, achievable starting point and an envisioned “ultimate goal” • Begin prototyping and trials immediately • Gain practical experience with prototypes, and adjust “wishlists” and requirements as we go • Make realistic estimates of cost and operational complexity based on early experience with prototype systems, rather than guess-work • Add features, complexity, and new technologies incrementally, based on experience to date • Repeatedly assess GENI’s current risk and usefulness as planning and construction unfold, and adjust plans accordingly

5. Spiral DevelopmentGENI grows through a well-structured, adaptive process • An achievable starting pointExample: Rev 1 “narrow waist”, federation of multiple substrates (clusters, wireless, regional / national optical net with early GENI ‘routers’, perhaps some existing testbeds), Rev 1 user interface and instrumentation. • Envisioned ultimate goalExample: Planning Group’s desired GENI facility, probably trimmed some ways and expanded others. Incorporates large-scale distributed computing resources, high-speed backbone nodes, nationwide optical networks, wireless & sensor nets, etc. • Spiral Development ProcessRe-evaluate goals and technologies yearly by a systematic process, decide what to prototype and build next.

FederationGENI grows by “gluing together” heterogeneous facilities over time Wireless#1 Corporate GENI facilities Backbone #1 ComputeCluster#1 GENI Slice supporting an experiment Other-Nation GENI facilities Access#1 Backbone #2 ComputeCluster#2 Other-Nation GENI facilities Wireless#2 NSF parts of GENI Goals: avoid technology “lock in,” add new technologies as they mature, and potentially grow quickly by incorporating existing facilities into the overall “GENI ecosystem”

10. GENI: The Facility • GENI is in Early Planning, But Some Requirements Have Become Clear • A Continent-Scale, Evolvable, Optical Substrate • Native Access for ~ 200 Universities • Native Access Will Be Considered for Non-Academic Sites • Wireless networks • Characteristics of Interest Include: Location Awareness, High Mobility, End-Users. • Support of Sensor Internet and Other Edge Research • Partnerships and Federations • Federation of GENI on International Scale Expected • We Expect This Will Associate With NSF’s International Connections Program • We Have Had Discussions About Facilities With GENI-like Qualities in the EU, Japan, Korea, China, Latin America and the United Arab Emirates • We Welcome Discussions
