4 Sponsored by the National Science Foundation4GENI Introductionwww.geni.net GENI: Infrastructure for Experimentation GENI provides compute resources that can be connected in experimenter specified Layer 2 topologies.

5 Sponsored by the National Science Foundation5GENI Introductionwww.geni.net Multiple GENI Experiments run Concurrently Resources can be shared between slices Experiments live in isolated “slices”

6 Sponsored by the National Science Foundation6GENI Introductionwww.geni.net 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

7 Sponsored by the National Science Foundation7GENI Introductionwww.geni.net GENI Compute Resources GENI Racks GENI Wireless compute nodes Existing Testbeds Emulab Planetlab ORBIT

8 Sponsored by the National Science Foundation8GENI Introductionwww.geni.net Creating and deploying GENI racks Ilia Baldine RENCI More resources / rack, fewer racks Rick McGeer HP Labs Fewer resources / rack, more racks Latest addition Rajesh Narayanan DELL KC Wang Clemson

9 Sponsored by the National Science Foundation9GENI Introductionwww.geni.net GENI Networking Resources Networking within a Rack National Research Backbones (e.g. Internet2) Regional Networks (e.g. CENIC) WiMAX Base Stations 4G/3G GENI network

10 Sponsored by the National Science Foundation10GENI Introductionwww.geni.net Federation GENI grows by GENI-enabling heterogeneous infrastructure Avoid technology “lock in” and grow quickly by incorporating existing infrastructure Backbone #1 Regional GENI Rack Access #1 Commercial Clouds Corporate GENI suites Non-US Testbeds Research Testbed Campus My experiment runs across the evolving GENI federation. My GENI Slice This approach looks remarkably familiar...

11 Sponsored by the National Science Foundation11GENI Introductionwww.geni.net GENI Architecture Flexible network / cloud research infrastructure Also suitable for physics, genomics, other domain science Distributed cloud (racks) for content caching, acceleration, etc. Metro Research Backbones Internet ISP Regional Networks Campus g g g Legend GENI-enabled hardware Layer 3 Control Plane Layer 2 Data Plane

12 Sponsored by the National Science Foundation12GENI Introductionwww.geni.net 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 locations within campuses, regionals, and backbone networks GENI Racks serve as programmable routers, distributed clouds, content distribution nodes, caching or transcoding nodes, etc

13 Sponsored by the National Science Foundation13GENI Introductionwww.geni.net 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

14 Sponsored by the National Science Foundation14GENI Introductionwww.geni.net Federation Extends the Reach of GENI and International Peer Testbeds Initial plan to federate testbeds on five continents

15 Sponsored by the National Science Foundation15GENI Introductionwww.geni.net Testbeds Involved Modified slide from: deration.pdf

16 Sponsored by the National Science Foundation16GENI Introductionwww.geni.net Outline What is GENI? How is GENI being used? Key GENI Concepts Demo: A simple experiment using GENI

17 Sponsored by the National Science Foundation17GENI Introductionwww.geni.net 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!

18 Sponsored by the National Science Foundation18GENI Introductionwww.geni.net Outline What is GENI? How is GENI being used? Key GENI Concepts Demo: A simple experiment using GENI

19 Sponsored by the National Science Foundation19GENI Introductionwww.geni.net 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

20 Sponsored by the National Science Foundation20GENI Introductionwww.geni.net 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 Create & Register Slice Researcher Aggregate Manager API - listResources - createSliver … Aggregate Manager Aggregate Resources users slice s clearinghouse projects Tool

21 Sponsored by the National Science Foundation21GENI Introductionwww.geni.net GENI: Terms and Definitions A slice : One or more resources provided by an aggregate –E.g. Bare machines, virtual machines, VLANs Backbone #1 Backbone #2 GENI Rack #3 GENI Rack #2 Access #1 Commercial Clouds Corporate GENI suites Other-Nation Projects Research Testbed GENI Rack #1 My GENI Slice My slice contains slivers from many aggregates.

22 Sponsored by the National Science Foundation22GENI Introductionwww.geni.net 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 RSpec for requesting a single node

23 Sponsored by the National Science Foundation23GENI Introductionwww.geni.net 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? Aggregate Manager Client ListResources(…) Advertisement RSpec CreateSliver(Request RSpec, …) Manifest RSpec ListResources(SliceName, …) Manifest RSpec

25 Sponsored by the National Science Foundation25GENI Introductionwww.geni.net 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.

26 Sponsored by the National Science Foundation26GENI Introductionwww.geni.net 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

27 Sponsored by the National Science Foundation27GENI Introductionwww.geni.net 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)
