Why GENI? Science Issues We cannot currently understand or predict the behavior of complex, large-scale networks Innovation Issues Substantial barriers to at-scale experimentation with new architectures, services, and technologies Credit: MONET Group at UIUC Society Issues We increasingly rely on the Internet but are unsure we can trust its security, privacy or resilience increasingly rely on our evolving technological and social networks, intertwined and worldwide in scale Paradigm Shifts and Global Communications are transforming societies and economies. These issues are becoming increasingly important with ubiquitous connectivity, IoT, cybercrime. 3

GENI: A Laboratory for Novel Networking Research GENI provides compute resources that can be connected in experimenter specified Layer 2 topologies.

GENI: Infrastructure for Experimentation GENI provides compute resources that can be connected in experimenter specified Layer 2 topologies. 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 may be virtualized and used by multiple experiments 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 Everything is programmable: Experimenters create and program custom topologies, protocols and flows Experimenters set up custom: topologies protocols forwarding

GENI is Precision Cyberinfrastructure All applications and services rely on cyberinfrastructure High performance applications and services need precision cyberinfrastructure The right resources In the right places Connected by the right network Running the right software

GENI is a Nationwide Edge Computing Platform Edge computing: A method of optimizing cloud computing systems by performing data processing at the edge of the network, near the source of the data. https://en.wikipedia.org/wiki/Edge_computing Graphic from NTT Network Innovation Laboratories Every rack is a “cloudlet” in the GENI Edge Cloud

The GENI Edge Cloud connects to ClouldLab, Chameleon and AWS The GENI Edge Cloud connects to CloudLab, Chameleon and Amazon AWS Enables experiments that use GENI and ClouldLab/AWS resources

GENI for Research and Education Future Internet Architectures Software defined networking Large scale evaluation of protocols Cloud networking Domain sciences Education Classes in: Computer Networking Distributed systems Cloud computing Wireless Communications Undergraduate, graduate GENI has over 12,000 users!

STEM Initiatives using GENI K-12 Grad/Undergrad Community GENI based Massive Open Online Courses (MOOCs) for the masses PlanIT: SimCIty like game set in students’ own city GENI as a remote, virtual lab for networking, distributed systems and cloud computing classes Bringing scientific instruments into the classroom virtually Immersive 3D environments for problem solving

Mars Rover Game Students at a high school in Colorado learn math and programming using the Mars Rover game The Mars Rover has crash landed and the student must help the rover repair itself, build shelter, and prepare for colonists before they arrive. The game is designed to engage high school students, effectively teach and assess their critical thinking, math, and programming skills. - https://www.adlnet.gov/mars-game

Last semester 638 students in 24 classes did labs on GENI GENI as a Remote Lab Over 4500 students have used GENI in classes taught by 73 instructors Last semester 638 students in 24 classes did labs on GENI Jennie Albrecht teaches a distributed systems class at Williams College, MA Students using GENI in a wireless networking class in Greece

Why use GENI for Education? No need to acquire and maintain expensive lab facilities 24x7 access from almost anywhere Enables new lab exercises Exercises based on expensive and uncommon resources 4G wireless base stations, long haul network links, programmable switches Promotes exploratory learning If student messes up a resource configuration, delete and start over No instructor or administrator intervention needed Shared community resource Community developed course modules Community supported mailing lists Wide area experiment on GENI One of many wireless resources available for GENI labs

GENI: Terms and Definitions 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 Projects Projects organize work on GENI All slices are created in the context of a Project Only Project Leads can create Projects Project Leads must be faculty Leads invite/add project members

Clearinghouse and Aggregates users slices clearinghouse projects Create & Register Slice Slice credentials Aggregate Manager API - listResources - createSliver … Researcher Tool Aggregate Manager Aggregate Resources 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 Sliver: One or more resources provided by an aggregate E.g. Bare machines, virtual machines, VLANs Campus #3 Commercial Clouds My slice contains slivers from many aggregates. Backbone #1 Campus My GENI Slice Corporate GENI suites Access #1 Backbone #2 Research Testbed Other-Nation Projects Campus #2 Update fig from earlier

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

Reserving Resources using RSpecs and the AM API Experimenter tools and aggregates talk to each other using resource specifications (RSpecs) and the GENI Aggregate Manager API (GENI AM API) Advertisement RSpec: What does an aggregate have? Request RSpec: What does the experimenter want? Manifest RSpec: What does the experimenter have? What do you have? I have … ListResources(…) I would like … Advertisement RSpec You have … CreateSliver(Request RSpec, …) Aggregate Manager Experimenter Tool What do I have? Manifest RSpec You have … ListResources(SliceName, …) Manifest RSpec

Demo: Putting it all Together Login to the GENI Portal Create a slice Create resources at one aggregate Two computers (VMs), connected by a LAN Generate traffic View results Delete resources

Hands on Exercise Based on the popular IP Routing exercise developed by Mike Zink of UMass, Amherst

Objectives For this workshop As a student lab Gain hands-on experience with GENI As a student lab Learn to set up static IP routes using the Linux route command (you will be given the solution) Lab0 on the GENI Course Modules page is a better first lab for your students as it includes account setup instructions.
