  3. Global networks are creatingextremely important new challenges Credit: MONET Group at UIUC 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

  4. GENI: Infrastructure for Experimentation GENI provides compute resources that can be connected in experimenter specified Layer 2 topologies.

  5. GENI: Infrastructure for Experimentation GENI provides compute resources that can be connected in experimenter specified Layer 2 topologies.

  6. Multiple GENI Experiments run Concurrently Resources can be shared between slices Experiments live in isolated “slices”

  7. 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

  8. GENI Compute Resources GENI Wireless compute nodes GENI Racks Existing Testbeds (e.g. Emulab)

  9. GENI Networking Resources National Research Backbones (e.g. Internet2) Networking within a Rack Regional Networks (e.g. CENIC) WiMAX Base Stations

  10. Outline • GENI – Exploring future internets at scale • The GENI Concept • Building GENI • Experimental and Classroom use of GENI • GENI: An experimenter’s view

  11. A bright idea “I have a great idea.” “That will never work.”

  12. 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.

  13. 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.

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

  15. “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.)

  16. ??

  17. 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!

  19. Growing GENI’s footprint

  20. FederationGENI grows by GENI-enabling heterogeneous infrastructure My experiment runs acrossthe evolving GENI federation. GENI Rack Commercial Clouds Backbone #1 Campus My GENI Slice Corporate GENI suites Access#1 Regional Research Testbed Non-US Testbeds This approach looks remarkably familiar . . . GENI Rack Avoidtechnology “lock in” and grow quickly by incorporating existing infrastructure

  21. Infeasible to build a testbed as big as the Internet Build GENI at sufficient scale HP ProCurve 5400 Switch NEC WiMAX Base Station GENI-enabled equipment GENI-enabled campuses, students as early adopters “At scale” GENI prototype • GENI-enable testbeds, commercial equipment, campuses, regional and backbone networks Campus photo by Vonbloompasha

  22. GENI architecture ISP Internet • Flexible network / cloud research infrastructure • Also suitable for physics, genomics, other domain science • Support “hybrid circuit” model plus much more (OpenFlow) • Distributed cloud (racks) for content caching, acceleration, etc. Metro Research Backbones g Layer 2 Data Plane GENI-enabled hardware g Legend Layer 3 Control Plane g Campus Regional Networks

  23. Georgia Tech: a great example • OpenFlow in 4 GT lab buildings now • Aware Home • Students will “live in the future” – Internet in one slice, multiple future internets in additional slices Nick FeamsterPI Ellen Zegura Russ Clark, GT-RNOC Ron Hutchins, OIT Trials of “GENI-enabled” commercial equipment Toroki LightSwitch 4810 HP ProCurve 5400 Switch Juniper MX240 Ethernet Services Router HTC Android smart phone NEC WiMAX Base Station GENI racks Arista 7124S Switch NEC IP8800 Ethernet Switch

  24. Example regional networkCENIC OpenFlow buildout

  25. 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

  26. 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

  27. Current GENI buildout • More WiMAX base stationswith Android handsets • GENI-enable 5-6regional networks • Inject moreOpenFlow switchesinto Internet2 • Add GENI Racks to 50 locationswithin campuses, regionals, andbackbone networks GENI Racks serve as programmable routers, distributed clouds, content distribution nodes, caching or transcoding nodes, etc

  42. GENI at Upcoming Conferences

  43. Outline • GENI – Exploring future internets at scale • The GENI Concept • Building GENI • Experimental and Classroom use of GENI • GENI: An experimenter’s view

  44. Access to GENI Leverage InCommonfor single sign-on authentication Experimenters from 304 educational and research institutions have InCommon accounts • For many experimenters: • no new passwords • familiar login screens GENI Project Office runs a federated IdP to provide accounts for non-federated organizations.

  45. The GENI Portal is… A web-based tool for experimenters to manage experimenters, projects, and slices.

  46. For GENI IdP Accounts … • Sign up with an institutional email address (ientua.gr email) that you have access to • Forwarding on that email address is ok • Reply to follow up email confirming that you made the request • The account creation process can take a couple of days.

  47. 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

  48. 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 Slice Authority Create & Register Slice Slice credentials Aggregate Manager API - listResources - createSliver … Researcher Aggregate Manager Aggregate Resources

  49. 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

  50. 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"?> <rspecxmlns="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
