What made PlanetLab successful?

Centralized trust

Centralized resource control

Decentralized management (unbundled management)

The bandwidth as free

Provide only best-effort service

Make Linux the execution environment

Do not provide distributed OS services (up to users)

Evolve the API

How we use GENI, how we build GENI?

How to use GENI: 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!


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 suite, and started taking measurements . . .

He uses a modest slice of GENI, sharing its facilities with many other concurrent experiments.


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!

His experiment grew larger and continued to evolve as more and more real users opted in . . .

Location-based social networks are really cool!

His slice of GENI keeps growing, but GENI is still running many other concurrent experiments.


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.


Moral of this storyGENI 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 suite of facilities on which experiments run

GENI creates a huge opportunity for ambitious research!GENI creates a huge opportunity for ambitious research!


GENI Spiral 1 has now begun!First results expected in 6-12 months

GENI Project Office Announces $12M forCommunity-Based GENI Prototype Development July 22, 2008

The GENI Project Office, operated by BBN Technologies, an advanced technologies solutions firm, announced today that it has been awarded a three year grant worth approximately $4M a year from the US National Science Foundation to perform GENI design and risk-reduction prototyping.

The funds will be used to contract with 29 university-industrial teams selected through an open, peer-reviewed process. The first year funding will be used to construct GENI Spiral 1, a set of early, functional prototypes of key elements of the GENI system.

GENI Engineering ConferencesMeet every 4 months to review progress together

3rd meeting Oct. 28-31, 2008 in Palo Alto, open to allReviews current GENI status, Working Group meetingsAlso discuss GPO solicitation, how to submit a proposal, evaluation process & criteria, how much money, etc. Travel grants to US academics for participant diversity

Subsequent Meetings, open to all who fit in the roomHeld at regular 4-month periodsHeld on / near university campuses (volunteers?)All GPO-funded teams required to participateSystematic, open review of each Working Group status(all documents and prototypes / trials / etc.)Also time for Working Groups to meet face-to-faceResults in prioritized list for next round of prototype funding areas (priorities decided by NetSE Council and GPO)
