  4. GENI OrganizationsMajor Research Equipment Facility Construction (MREFC) NSF Program Director GENI Chair Project Director GENI Science Council (GSC) GENI Project Office (GPO) • Voice of research and education community • Scientific leadership - evolution of Science Plan • Define user allocations process & criteria • Development of education & outreach plan • Research infrastructure experience – software-intensive • projects • Experience with computing community • Project management – MREFC process • GPO is at BBN • GENI Project Director is Chip Elliot

  5. GENI To Date • The community has engaged in concept development since 2004-2005 • NSF CISE funding has supported • Early concept development – GENI Planning Group • Early prototype development • Solicitation for proposals to establish GENI Project Office • GENI Science Council was established in Spring of 2007 • GENI Project Office was awarded to BBN in May 2007

  6. Project Life Cycle • Formal NSF process to be followed to qualify for budget consideration • Preconstruction Planning - Three formal design stages, with well-defined interfaces • Construction • Operations

  13. NSF CISE Future Internet Research Experimental Facility to Validate Research GENI

  14. FIND • www.nets-find.net has much material, including full descriptions of projects • White paper program • Rolling requests for researchers with funding on architectural, big picture research • Clean-slate • Join collaborative program with other researchers • See the web site for more information on white papers

  15. What is GENI? GENI will be a full-scale programmable facility for research into the future internet • Focus: whatever experiments researchers need to create, test and evaluate the high impact new ideas • Clean-slate approach, Opportunity for: • Unencumbered starting points • Novel architectures and big picture • Strong coupling with technology drivers of futures • Mobile wireless • Novel optical substrate capability

  16. GENI Design: Building Blocks • Three major components • Physical network ‘substrate’ • expandable collection of building block components • federate • Software control & management framework • knits building blocks together into a coherent facility • embeds ‘slices’ in the physical substrate • Operational control (GENI management) is distinct from experiment control • Components • design, build, operate, iterate in modules, throughout lifecycle

  17. GENI Design – • Fully Programmable Routing/Switching Nodes • Clean-slate for architecture and protocol research • Slicing/Virtualization of Physical “Substrate” • Concurrent exploration of a broad range of experimental networks (including edge resources such as clusters) • Guaranteed resources, interference free will be available • Instrumented resources • Fully Measure experimental behavior • Interconnect GENI and the commodity internet • Users and applications can “opt-in” to GENI • There will be access to both “customers” for novel long-lived services and to “populations” of real users • Flexible and Phased Design • To support new technology introduction throughout GENI lifetime • See A Tale of Two GENI’s on GENI.net site!

  19. FederatedInternational Facility Federation Example

  20. Programmability • Basic Approach • All network elements are programmable via open interfaces and downloadable user code • Uniform control and management architecture across all components – access node, core node, wireless… GENI Control & Management Plane API Programmable Edge Node Programmable Sensor Platform Open API Radio platform Programmable core Node

  21. Wireless Substrate Considerations (presented to MobOpts RG July 25 2007)

  22. NSF Wireless Testbed Experience • Programmable wireless and sensor network testbeds were developed in earlier NSF progams • ORBIT for evaluation of wireless network protocols • CitySense, Kansei open programmable sensor net testbeds • Coming this year: open underwater net • These open testbeds offer shared use and programmable layer 2/layer 3 protocols but full future internet impact needs full scale ORBIT Radio Grid Emulator ORBIT Field Trial Network Harvard/BBN CitySense deployment plan

  23. Candidate GENI Wireless: Dealing with Heterogeneity • This is the prototype design - a candidate platform • Single wireless GENI node architecture that covers different wireless device and network element needs: • Standard set of CPU platforms with different size/performance • Multiple radio cards as “plug-in” – easy to change radios, upgrade • Linux OS with appropriate “open API” drivers GENI M&C (“GMC”) Linux OS Control Module Linux OS w/ GENI control Plug-In radio modules (evolving technology,..) Processor Chassis with appropriate size/performance (sensor GW, mobile node, ad hoc router, AP, BTS…) End-user Wireless Devices (commercial sensors, phones, PDA’s, laptops) With GENI opt-in? Wireless GENI Network Elements All components also available as wireless kits

  24. GENI Candidate: Programmable, Cognitive Radios • Several experimental programmable radio platforms under development for wireless network research… • WARP programmable radio, GNU radio, KU agile radio & near-future cognitive radios, …. • Key issue: open software API’s and protocol stacks for full control of physical and link/MAC layers GNU Software Radio KU Agile Radio Lucent/WINLAB Cognitive Radio 802.11 AP Rice “WARP” board

  25. Some Ongoing Discussions • How do we do systems engineering and planning for fast evolving radio / wireless substrates? • How much can radio / wireless be virtualized? • GENI performance in general? • How much scale-down is acceptable per element? • How can a project/experiment buy better performance fidelity, and how much? • Missing key radio (and optical, other physical) Areas? • Optical access networks? • Wireless over fiber? • Quantum Cryptography?

  26. GENI Success Scenarios (many alternatives) • Internet evolution influenced by clean-slate approach • Architectures achieve fundamental progress in challenge areas such as security • New services and applications enabled • Alternate Internet architecture emerges • Virtualization becomes the norm with plurality of architectures • Single new architecture from the research enabled by GENI emerges and dominates • Alternative infrastructure becomes the mainstream over time • Many other payoffs, including unanticipated and high risk

  27. Extra - Scope of GENI Optical Research? • Tight Integration of Physical Layer with Higher Layers • Provide Dynamic Optical Networking Plane • Dynamic Optical Switching/Routing • Fiber (Space) Switch (e.g. switch all WDM channels in a fiber) • Wavelength Switching (e.g. ROADM) • Sub-Wavelength Switching (circuit) - O/E/O • Optical Burst/Packet Switching? • All Optical Networking • Combines Transmission Issues with Optical Switching/Routing • Data Rates/Modulation Formats effect Network Design • Control Plane / Management • Optical Transmission? • Higher Data Rates, Longer Transmission Distance, Modulation Formats • Quantum Cryptography • Optical Device Technologies?

  28. Optical Device Technologies? • Photonic Integrated Circuits (PICs) • Very dense and inexpensive OEO (scaling & cost reduction) • High Functionality PICs • Silicon photonics • Integration with electronics • Manufacturing Infrastructure Sharing (scaling & cost reduction) • Microstructured Optical Fibers • Customizable optical properties (transmission/all optical networks) • How would these breakthroughs change networking? • More efficient transmission or fundamental paradigm shift? GOAL: Flexible GENI design to allow Introduction of New Technologies as they mature
