1 Sponsored by the National Science Foundation1April 8, 2014, Testbeds as a Service: GENI Heidi Picher Dempsey Internet2 Annual Meeting April 8, 2014 www.geni.net

2 Sponsored by the National Science Foundation2April 8, 2014, GENI provides a virtual lab for networking and distributed systems research and education GENI started with exploratory, rapid prototyping 5 years ago GENI design assumes federation of autonomously owned and operated systems Yearly prototyping cycle for an idea: develop, integrate and operate Experimenters use the testbed while we are building it out Even prototypes have “activist” users, and must evolve to satisfy those users or fade away. Two of five original design frameworks predominate now. “Horizontal” dataplane slicing as a service (or sometimes just engineered) “Vertical” control plane APIs to negotiate and allocate resources Funds in hand Needs funding

3 Sponsored by the National Science Foundation3April 8, 2014, GENI: Infrastructure for Experimentation GENI provides compute, network, and wireless resources that can be connected in experimenter-specified Layer 2 topologies.

4 Sponsored by the National Science Foundation4April 8, 2014, GENI: Infrastructure for Experimentation GENI provides compute resources that can be connected in experimenter specified Layer 2 topologies.

5 Sponsored by the National Science Foundation5April 8, 2014, Multiple GENI Experiments run Concurrently Resources can be shared between slices Experiments live in isolated “slices”

6 Sponsored by the National Science Foundation6April 8, 2014, 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

7 Sponsored by the National Science Foundation7April 8, 2014, United States GENI Resources Flexible network / cloud research infrastructure Over 1800 users (March, 2014) 52 racks installed/in progress 10 WiMAX (50 LTE planned) VMs, bare metal nodes, SDN switches (OpenFlow 1.0), software routing or OVS OpenFlow, WiMAX/LTE base stations and clients all available to experimenters. Metro Research Backbones Internet ISP Regional Networks Campus g g g Legend GENI-enabled hardware Layer 3 Control Plane Layer 2 Data Plane

8 Sponsored by the National Science Foundation8April 8, 2014, International Federation Activities International Federation API for clearinghouse functions. Supported for multiple clearinghouses. Joint GENI/FIRE (US/EU) capability demonstrated this year (not operating yet) GENI dataplane slices extend to other research networks by special arrangement now (Japan, Korea, Australia) Shared monitoring prototype planned for 2014 Investigating/prototyping standards for experimenter-driven dataplane resource negotiation and provisioning NSI, OSCARS GENI Stitching SDN Exchanges

9 Sponsored by the National Science Foundation9April 8, 2014, Campus Requirements for Shared Services Sites provide space, power, security (as with other campus IT resources) Provide at least 1Gbps OpenFlow/SDN path from rack to campus boundary * Provide connection from rack to on-campus resources (varies by campus, usually SDN)* Operate with up-to-date GENI-specified software (e.g. AM API, OpenStack) Provide no-cost access to rack resources for GENI authorized users at other campuses Provide points of contact for GENI response team (see http://groups.geni.net/geni/attachment/wiki/ComprehensiveSecurityPgm/Aggregate Provider Agreement v3.pdf ) * http://groups.geni.net/geni/attachment/wiki/ComprehensiveSecurityPgm/Aggregate Provider Agreement v3.pdf * No STP or MAC learning

15 Sponsored by the National Science Foundation15April 8, 2014, Slice credentials Software: 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 Aggregate Manager API (AM API) –http://groups.geni.net/geni/wiki/GAPI_AM_API_V3 most recent versionhttp://groups.geni.net/geni/wiki/GAPI_AM_API_V3 –http://trac.gpolab.bbn.com/gcf download reference implementation (gcf), OMNI command line clienthttp://trac.gpolab.bbn.com/gcf –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

17 Sponsored by the National Science Foundation17April 8, 2014, Software: 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
