  1. FINDing a GENI in a CCCastle Reinventing the Internet (and More) – January 2007 Ellen W. Zegura

  2. My role in GENI • Member of GENI Research Coordination Working Group • Member of CRA GENI Community Advisory Board (interim body) • Member of CCC Interim Council (interim body) • Thanks to Dave Clark, Peter Freeman, Guru Parulkar, many others for raw material Footer Information

  3. Outline • A short story • What is GENI? • A research program (see FIND) • A “facility” for experimenting at scale • CCC and other acronyms • Opportunities Footer Information

  4. Once upon a time… • There was a research project ARPANET Logical Map, March 1977 Footer Information

  5. That grew up to be the Internet. Footer Information

  6. Applications Kazaa VoIP Mail News Video Audio IM U Tube Transport protocols TCP SIP UDP RTP Times changed, and it kept up… Everything on WEB HTTP IP IP on everything Ethernet 802.11 Power lines ATM Optical Satellite Bluetooth Modified John Doyle Slide Footer Information

  7. User Communications Games Photography User Inventory/Sales tracking Banking and Commerce Entertainment Systems Health/Medical User Home Computer Surveillance and Security (at home, work, or in public) Home Appliances PDA Car Telephone Building Automation User And everyone (and thing) relied on it. Footer Information

  8. Then one day, • People realized it wasn’t working so well • Lots of spam • Phishing attacks to steal identity and more • Too hard to set up my home network • Can’t tell why it isn’t working • Would you have tele-surgery over the Internet? • (Why) is Google building their own network? • And there were things it couldn’t do • “Can you print my dream?” (4 year old Bethany) Footer Information

  9. Scientists were heroic (and stymied) • What is the Internet structure? • How does it change and why? • How robust is the Internet? • What happens during a failure event? • What are the properties of Internet paths? • How do attacks propagate? • What are users doing? Footer Information

  10. Even experts had to admit: • “… in the thirty-odd years since its invention, new uses and abuses, …, are pushing the Internet into realms that its original design neither anticipated nor easily accommodates.” • “Freezing forevermore the current architecture would be bad enough, but in fact the situation is deteriorating. These architectural barnacles—unsightly outcroppings that have affixed themselves to an unmoving architecture— may serve a valuable short-term purpose, but significantly impair the long-term flexibility, reliability, security, and manageability of the Internet.” Overcoming Barriers to Disruptive Innovation in Networking, NSF Workshop Report, 2005.

  14. GENI research program • FIND: U.S. National Science Foundation program to fund research on Future Internet Design (focus on architecture) • Key areas of concern: • Security and robustness • Mobility of hosts and networks • Control and management • Addressing, naming and (inter-domain) routing • End-to-end principle vs in-network processing Footer Information

  15. Security trends • Increasing vulnerabilities, viruses, attacks, worms … • 20 new vulnerabilities reported every day • 120,000 known viruses and worms -- 50 new ones per day • Large scale attacks doubling every year • Increasing economic cost • Viruses alone => $60B • Worldwide => $105B+ • Some ISPs have more than 90% traffic that is spam • Identity thefts has emerged as a significant and serious threat • And more … Source: Spafford Talk Footer Information

  16. In the Future Internet • Information disclosure control and integrity • Important and well understood • High availability -- suitable for even mission critical scenarios • Balance of privacy and accountability • Usable security for a range of users • Context aware • Different parts of the world have different requirements • Appropriate for emerging devices and networks • Mobile wireless and sensor networks, sensors, PDAs, … Need coherent and comprehensive design Footer Information

  27. Outline • A short story • What is GENI? • A research program (see FIND) • A “facility” for experimenting at scale • CCC and other acronyms • Opportunities Footer Information

  28. What is the CCC? • Computing Community Consortium • Solicited by US NSF, “calling for the computing research community to unite in the establishment of a Computing Community Consortium” • Serve as “a community proxy responsible for facilitating the conceptualization and design of promising infrastructure-intensive projects identified by the computing research community to address compelling scientific ‘grand challenges’ in computing.” • Initial responsibility would be “guiding the design of the Global Environment for Network Innovations (GENI) … on behalf of the research community, ensuring broad community participation in the GENI design process and identifying necessary pre-construction development activities.” • Award made to Computing Research Association (CRA) Footer Information

  29. And eventually there will be • CCC Council • Interim group appointed November 2006 • Nominations for members due late Jan 2007 • GENI Science Council (GSC) • Interim group appointed October 2006 • Nominations for members in November 2006 • Initial permanent group to be named soon • GENI Project Office (GPO) • Solicitation in fall 2007 • Award due in spring 2007 Footer Information

  30. Opportunities • Researchers • Contribute to research vision and agenda • Engage in peer-to-peer collaborations and conversations about experiments • Researchers+Government • Industry Footer Information

  31. International Partnerships Important • Help define facility scope • Build national partner facilities to complement US GENI facilities and capabilities • Share facilities with researchers in all partner countries • Encourage collaborative international research projects and experiments Footer Information

  32. Industry Partnerships Important • Help to refine R&D objectives • Become a member in the GENI consortium • Provide leading-edge technology for use in GENI • Contract (or subcontract) to build the facility • Conduct collaborative research with universities • Benefits to partnering • Accelerate the transfer of academic research results to commercial products • Enable a national/international “proving ground” for new technology Footer Information

  33. Conclusions • The future of the Internet is too important to be left to chance or random developments. • True experimentation is needed. • The GENI project intends to provide the basic architectures, technologies, and policies that will be needed for successful networking in the 2010-2020 time frame.
