What is GENI? How is GENI being used? Key GENI Concepts Demo: A simple experiment using GENI


GENI: Infrastructure for Experimentation

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

Presenter

Presentation Notes

GENI is a nationwide suite of infrastructure for�“at scale” experiments in networking, distributed systems, security, and novel applications.� GENI opens up huge new opportunities Leading-edge research in next-generation internets Rapid innovation in novel, large-scale applications Key GENI concept: slices & deep programmability Internet: open innovation in application programs GENI: open innovation deep into the network


Multiple GENI Experiments run Concurrently

Resources can be shared between slices

Experiments live in isolated

“slices”


GENI is “Deeply Programmable”

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

switches using OpenFlow

OpenFlow part of the experiment not only the infrastructure

GENI Architecture

• Flexible network / cloud research infrastructure

• Also suitable for physics, genomics, other domain science

• Distributed cloud (racks) for content caching, acceleration, etc.

Current GENI buildout

• More WiMAX base stations with Android handsets

• GENI-enable 5-6 regional networks

• Inject more OpenFlow switches into Internet2

• Add GENI Racks to 50-80 locations within campuses, regionals, and backbone networks

GENI Racks serve as programmable routers, distributed clouds, content

distribution nodes, caching or transcoding nodes, etc


GENI Operations

GMOC: GENI Meta-operation Center • Keeps track of outages • Notification system for resource reservation • Monitors most GENI Aggregates

GMOC Google Calendar keeps track of reservations/outages


Federation Extends the Reach of GENI and International Peer Testbeds

Initial plan to federate testbeds on five continents

How is GENI being Used?

Research • Future Internet

architectures • Software defined

networking • Large scale evaluation of

smart grid protocols

Education • Over 50 classes using

GENI in all levels • Networking and

Distributed systems classes

• Cloud computing classes • WiMAX classes

As of October 2014, GENI has over 2700 users!


Outline



GENI: Terms and Definitions

– An experiment uses resources in a slice

– Slices isolate experiments

– Experimenters are responsible for their slices

Slice Abstraction for a collection of resources capable of running experiments


Slice credentials

Clearinghouse and Aggregates

• Clearinghouse: Manages users, projects and slices – Standard credentials shared via custom API or new Common CH API – GENI supported accounts: GENI Portal/CH, PlanetLab CH, ProtoGENI CH

• Aggregate: Provides resources to GENI experimenters – Typically owned and managed by an organization – Speaks the GENI AM API – Examples: PlanetLab, Emulab, GENI Racks on various campuses

GENI: Terms and Definitions

• A slice : One or more resources provided by an aggregate – E.g. Bare machines, virtual machines, VLANs

My GENI Slice

My slice contains slivers from many aggregates.


Resource Specifications (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

<?xml version="1.0" encoding="UTF-8"?> <rspec xmlns="http://www.protogeni.net/resources/rspec/2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.protogeni.net/resources/rspec/2 http://www.protogeni.net/resources/rspec/2/request.xsd" type="request" > <node client_id="my-node" exclusive="true"> <sliver_type name="raw-pc" /> </node> </rspec> RSpec for requesting a single node


Resource Reservation using RSpecs and the AM API

• Advertisement RSpec: What does an aggregate have?

• Request RSpec: What does the experimenter want? • Manifest RSpec: What does the experimenter have?

Access to GENI

For many experimenters: • no new passwords • familiar login

screens

Leverage InCommon for single sign-on authentication

Experimenters from 304 educational and research institutions have InCommon accounts

GENI Project Office runs a federated IdP to provide accounts for non-federated organizations.

Presenter

Presentation Notes

The GENI Portal trusts identity providers who are members of the InCommon federation. Students, faculty and staff will have an account provided by their school (for example, the University of Utah) which they use to access campus resources. They can then use that account to login to GENI as long as their school is a member of InCommon (with some caveats). **This is exactly like using your Facebook or Google account to access other websites.** For those experimenters, there are no new passwords. For all others, we are happy to make you an account on the GPO’s identity provider. Anyone with an account at a supported identity provider (usually your school or employer) can log in, but they will have no privileges If you don’t have such an account, we will make you an account at the GPO Identity Provider You must be a member of a project to do anything interesting


NTUA is now federated …

1. Choose National Technical University of Athens from the drop down list

2. Use your NTUA username and password to login

Presenter

Presentation Notes

The GENI Experimenter Portal is fundamentally about managing experimenters, projects and slices (we’ll define these terms in a minute). But it also has tools for doing resource reservation. (Note that new tools are being integrated with the Portal all the time.)


Putting it all Together: Demo

• Demo – Create a slice – Create a sliver at one

aggregate • Two computers (raw PCs),

connected by a LAN

– Install and run software on the machines

– View output of software – Delete sliver

• Experimenter tool: Jacks

server (VM)

client (VM)
