Society IssuesWe increasingly rely on
the Internet but are unsure we can trust its
security, privacy or resilience
Science IssuesWe cannot currently
understand or predict the behavior of complex,large-scale networks
Innovation IssuesSubstantial barriers to
at-scale experimentation with new architectures, services,
and technologies
Global networks are creatingextremely important new challenges

GENI: Infrastructure for Experimentation
GENI provides compute resources that can be connected in experimenter specified Layer 2 topologies.
Sponsored by the National Science Foundation 6GENI Introduction – 27 October 2013 www.geni.net
Multiple GENI Experiments run Concurrently
Resources can be shared
between slices
Experiments live in isolated “slices”
Sponsored by the National Science Foundation 7GENI Introduction – 27 October 2013 www.geni.net
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

“I have a great idea.”
“That will never work.”
A bright idea
Sponsored by the National Science Foundation 12GENI Introduction – 27 October 2013 www.geni.net
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.
Sponsored by the National Science Foundation 13GENI Introduction – 27 October 2013 www.geni.net
It turns into a really good idea
His slice of GENI keeps growing, but GENI is still running many other concurrent experiments.
This service looks very useful

“Looks like an app to me.”
“It’s my very own GENI slice.”
Attracts real users

“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.)

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!

GENI on Internet2 A major step towards campus expansion
• Collaboration to implement national-scale infrastructure– sliced and deeply-programmable– incorporating OpenFlow/SDN switches, GENI Racks, etc.– high-speed (10-100 Gbps)
• With software that supports shared use by faculty, students, and campus IT organizations
• In-progress migration from “prototype GENI” to AL2S production system
• Scaling to an envisioned goal of 100-200 GENI campuses
• ION AM to support dynamic provisioning within Internet2

GENI WiMAX Agreements
• 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

Rapid growth in experimentation
GENI tools being developed support complex experiments
• GENI is gaining tractions with experimenters- More experimenters sign up (> 1000)- More experimenters are actively using GENI
• GENI expansion creates opportunities for experienced experimenters to create complex experiments- Better tools to manage
experiments- Tools to monitor - Support of services running
in GENI

GENI: Terms and Definitions
– An experiment uses resources in a slice
– Slices isolate experiments
– Experimenters are responsible for their slices
SliceAbstraction for a collection of resources capable of running experiments

Slice credentials
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

RSpecs
• RSpecs: Lingua franca for describing and requesting resources– “Machine language” for negotiating resources between experiment
and aggregate– Experimenter tools eliminate the need for most experimenters to
write or read RSpec
