  • GENI is a nationwide suite of infrastructure for“at scale” experiments in networking, distributed systems, security, and novel applications.GENI opens up huge new opportunitiesLeading-edge research in next-generation internetsRapid innovation in novel, large-scale applicationsKey GENI concept: slices & deep programmabilityInternet: open innovation in application programsGENI: open innovation deep into the network

  • Experimenters set up custom:topologies protocols forwarding
  • Flexible network / cloud research infrastructure, suitable for other domain sciencesAlso suitable for physics, genomics, other domain scienceSupport “hybrid circuit” model plus much more (OpenFlow)Distributed cloud (racks) for content caching, acceleration, etc

    1. 1. Sponsored by the National Science Foundation GENI Exploring Networks of the Future Niky Riga, GENI Project Office US Ignite ONF Joint Workshop www.geni.net
    2. 2. Sponsored by the National Science Foundation 2GENI – 8 Oct 2013 www.geni.net GENI: Infrastructure for Experimentation GENI provides compute resources that can be connected in experimenter specified Layer 2 topologies.
    3. 3. Sponsored by the National Science Foundation 3GENI – 8 Oct 2013 www.geni.net GENI: Infrastructure for Experimentation GENI provides compute resources that can be connected in experimenter specified Layer 2 topologies.
    4. 4. Sponsored by the National Science Foundation 4GENI – 8 Oct 2013 www.geni.net Multiple GENI Experiments run Concurrently Resources can be shared between slices Experiments live in isolated “slices”
    5. 5. Sponsored by the National Science Foundation 5GENI – 8 Oct 2013 www.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

Sponsored by the National Science Foundation 6GENI – 8 Oct 2013 www.geni.net Envisioned architecture Metro Research Backbones InternetISP U N I V E R S I T YU N I V E R S I T Y U N I V E R S I T YU N I V E R S I T Y Regional Networks Campus g g gLegend GENI-enabled hardware Layer 3 Control Plane Layer 2 Data Plane Federation of GENI-enabled resources
    7. 7. Sponsored by the National Science Foundation 7GENI – 8 Oct 2013 www.geni.net Key GENI differences 1. Shareable deep-programmability • multi-purpose 2. Federation of resources • no single administrative domain • plug-and-play 3. Timescale of deployments • mostly short-lived experiments 4. Network Innovation
    8. 8. Sponsored by the National Science Foundation 8GENI – 8 Oct 2013 www.geni.net Current GENI OpenFlow deployment  Share OpenFlow resources with FlowVisor  Hardware switches running OpenFlow 1.0  Most switches run in hybrid mode
    9. 9. Sponsored by the National Science Foundation 9GENI – 8 Oct 2013 www.geni.net Slice Support … • Native isolation between “slices” • Better performance • Faster adoption of new standards • Run different OF versions in the same HW switch Natively share the same physical OpenFlow switch Image from: http://www.goodfon.com/wallpaper/165816.html
    10. 10. Sponsored by the National Science Foundation 10GENI – 8 Oct 2013 www.geni.net Enable innovation … OpenFlow as the means: • robust underlying platform for developing/running simple controllers • similar OpenFlow devices similar core support • well documented behavior OpenFlow research: • ability to write OpenFlow extensions • experimenters not infrastructure owners Ability to quickly innovate across diverse infrastructure
    11. 11. Sponsored by the National Science Foundation 11GENI – 8 Oct 2013 www.geni.net … “out of the box” Cutting-edge network research: • Functionality needed might not be supported by current hardware switches • In-network ability to: • store packets • manipulate packets (e.g. encode/decode) • Easy transition to production GENI Racks serve as programmable routers, distributed clouds, etc OpenFlow + general purpose compute => Push networking to the future
