About GENI ….a continental-scale, programmable,

heterogeneous, networked system driving “clean-slate” future internet / communications research

Mobile Wireless Network

Edge Site

FederatedInternational Facility

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

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

Spiral DevelopmentGENI grows through a well-structured, adaptive process An achievable starting point

Example: 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 goal Example: 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

Goals: avoid technology “lock in,” add new technologies as they mature, and potentially grow quickly by incorporating existing facilities into the overall “GENI ecosystem”

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
