5. A bright idea I have a great idea! The original Internet architecture was designed to connect one computer to another – but a better architecture would be fundamentally based on PEOPLE and CONTENT! That will never work! It won’t scale! What about security? It’s impossible to implement or operate! Show me! www.geni.net

6. Trying it out My new architecture worked great in the lab, so now I’m going to try a larger experiment for a few months. And so he poured his experimental software into clusters of CPUs and disks, bulk data transfer devices (‘routers’), and wireless access devices throughout the GENI facility, and started taking measurements . . . He uses a modest slice of GENI, sharing the facility with many other concurrent experiments. www.geni.net

7. It turns into a really good idea Boy did I learn a lot! I’ve published papers, the architecture has evolved in major ways, and I’m even attracting real users! Location-based social networks are really cool! His experiment grew larger and continued to evolve as more and more real users opted in . . . His slice of GENI keeps growing, but GENI is still running many other concurrent experiments. www.geni.net

8. Experiment turns into reality My experiment was a real success, and my architecture turned out to be mostly compatible with today’s Internet after all – so I’m taking it off GENI and spinning it out as a real company. I always said it was a good idea, but way too conservative. www.geni.net

9. Meanwhile . . . I have a great idea! If the Internet were augmented with a scalable control plane and realtime measurement tools, it could be 100x as reliable as it is today . . . ! And I have a great concept for incorporating live sensor feeds into our daily lives ! If you have a great idea, check out the NSF FIND, SING, or NGNIprograms which are funding new architectural work. www.nets-find.net www.geni.net

10. Moral of this story • 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 • A reminder . . . • GENI itself is not an experiment ! • GENI is a stable facility on which experiments run GENI creates a huge opportunity for ambitious research! www.geni.net

11. How We’ll Build GENI Note that this is the “classics illustrated” version – a comic book!Please read the GENI Project Development Plan (PDP) and Project Execution Plan (PEP) for detailed planning information. www.geni.net

12. An ambitious goal The GENI facility will allow experiments to incorporate all the key technologies for global networks and distributed services within a 10-20 year time frame – specifically CPU & disk farms, programmable ‘routers’, optical networks, and wireless access. That’s way too ambitious! Exactly what wireless? or optics? Technology becomes obsolete fast! Overlays are all you’ll ever need! Nobody will use it –it’s a white elephant! www.geni.net

13. Managing real risks • You are identifying important risks. • A typical “blueprint then execute” process suitable for building many kinds of predictable engineering projects (such as chemical plants) will lead to extremely high levels of risk if used for planning and building GENI. • Our plan for building GENI successfully relieson two main risk-management techniques: • Spiral development • Federation www.geni.net

14. Spiral DevelopmentGENI grows through a well-structured, adaptive process • An achievable starting pointExample: Rev 1 control framework, 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. Planning Design Use Use Integration Build out Strawman GENI Construction Plan www.geni.net

15. FederationGENI grows by “gluing together” heterogeneous facilities over time My experiment runs acrossthe evolving GENI federation. Wireless#1 Corporate GENI facilities Backbone #1 ComputeCluster#1 My GENI Slice Other-Nation GENI facilities Access#1 Backbone #2 ComputeCluster#2 This approach looks remarkably familiar . . . 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” www.geni.net

16. It’s all about managing risksThe Central Goal of GENI Planning and Construction We’ll take it little by little. Those parts of GENI that are widely used will grow; those that aren’t, won’t get more funding. But it won’t be impromptu or ad hoc – we will follow a well-defined, formal process throughout: spiral development. I see. We are avoiding an “all or nothing” gamble – we don’t try to specify all of GENIright now, then live with it for the next 20 years. Thank heavens! www.geni.net

17. Moral of this story • GENI has real risks . . . • Many have been identified already • Others will emerge as prototyping / construction get underway • The “white elephant” risk is certainly real, as are many technological risks including rapid obsolescence • Accurate understanding of operating expenses will be critical • Risk management is central to GENI planning • “Winging it” would almost surely lead to disaster • Systematic, formal processes must be used identify and drive down risks throughout planning and construction • Spiral development and federation greatly reduce risk • Rapid prototyping should begin immediately, as a key technique for risk reduction in GENI’s planning phase www.geni.net

23. 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 www.geni.net

26. GENI will be Designed & Built by the CommunityVia an Open, Transparent, & Fair GPO Process • All design, prototyping, & construction will be performed by the research community (academia & industry) • Openness will be emphasized • Design process will be open, transparent, and broadly inclusive • Open-source solutions will be strongly preferred • Intellectual property is OK, under no-fee license for GENI use • GPO will be fair and even-handed • BBN brings no technology to the table • BBN does not intend to write any GENI software, nor does it envision bidding on any prototyping or construction activities(but “never say never”) • If BBN does create any GENI technology, it will be made public at no cost www.geni.net

27. Working Groups will drive GENI’s Technical Design Meet every 4 Months to Review Progress Together • Working Groups, open to all • The locus for all GENI technical design • Patterned on the early IETF • Discuss by email, create documents, meet 3x per year in person • Each led by Chair(s), plus a professional System Engineer • GENI Engineering Conferences, open to all who fit in the room • Held at regular 4-month periods • Held on / near university campuses (volunteers?) • All GPO-funded teams required to participate • Systematic, open review of each Working Group status(all documents and prototypes / trials / etc.) • Also time for Working Groups to meet face-to-face • Results in prioritized list for next round of prototype funding areas (priorities decided by GSC and GPO) www.geni.net

28. How the GPO will FundRapid Prototyping and Experiments • Needs are driven by “long poles” in GENI construction – the high risk design and technology areas • High risks are identified at 4-month intervals by GSC / GPO review panel • GPO issues solicitations once or twice per year • Proposals are merit-reviewed by NSF-style panels • GPO continuously monitors contracts for performance • Quick decisions and quick funding are essential • Goal is to have multiple development teams up to speed in each area before construction begins, who can then bid on the big construction contracts www.geni.net
