Science Issues

We cannot currently understand or predict the behavior of complex,large-scale networks

Innovation Issues

Substantial barriers toat-scale experimentation with new architectures, services, and technologies

Society Issues

We increasingly rely on the Internet but are unsure we can trust its security, privacy or resilience

geni i nfrastructure for experimentation
GENI: Infrastructure for Experimentation

GENI provides compute resources that can be connected in experimenter specified Layer 2 topologies.

geni i nfrastructure for experimentation1
GENI: Infrastructure for Experimentation

GENI provides compute resources that can be connected in experimenter specified Layer 2 topologies.

multiple geni experiments run concurrently
Multiple GENI Experiments run Concurrently

Resources can be shared between slices

Experiments live in isolated “slices”

geni is deeply programmable
GENI is “Deeply Programmable”

I install software I want throughout my network slice (into routers, switches, …) or control switches using OpenFlow

Experimenters can set up custom topologies, protocols and switching of flows

a bright idea
A bright idea

“I have a great idea.”

“That will never work.”

slide12

Let’s try it out!

My new architecture worked great in the lab, so now I’m going to try a larger experiment for a few months.

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

it turns into a really good idea
It turns into a really good idea

This service looks very useful

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

slide14

Attracts real users

“Looks like an app to me.”

“It’s my very own GENI slice.”

slide15

“Boy did I learn a lot!”

“What a cool service.”

(I wonder how it works.)

“I always said it was a great idea.”

(But way too conservative.)

slide16

??

If you have a great idea, check out theNSF CISE research programs for current opportunities.

moral of this story
Moral of this story

GENI is meant to enable . . .

At-scale experiments

Internet-incompatible experiments

Both repeatable and “in the wild” experiments

‘Opt in’ for real users

Instrumentation and measurement tools

GENI creates a huge opportunity for ambitious research!

  • Agreement with Clearwire
    • Clearwire and Rutgers University have signed a master agreement
    • encompassing all WiMAX sites, to ensure operation in the EBS Band.
    • An emergency stop procedure, in case of interference with Clearwire service, has been agreed upon.
  • GENI Mobile Virtual Network Operator (MVNO)

- Partner with Sprint and Arterra (a Sprint partner) to create and operate an (MVNO) that serves the academic research community

- The effort is led by Jim Martin, Clemson Univ, and is underway with a 1 year NSF EAGER

Slice

Abstraction for a collection of resources capable of running experiments

  • An experiment uses resources in a slice
  • Slices isolate experiments
  • Experimenters are responsible for their slices
geni terms and definitions1
GENI: Terms and Definitions
  • Slice authority: Creates and registers slices
    • GENI slice authorities: PlanetLab, ProtoGENI, GPO Lab
  • Aggregate: Provides resources to GENI experimenters
    • Typically owned and managed by an organization
    • Examples: PlanetLab, Emulab, GENI Rack on various campuses
    • Aggregates implement the GENI AM API
