  • Something about NSF/CISE (as there are no slides on our mission, etc.) : Mission: transformative science and education CISE: responsible for most basic federally-funded CS research in the country; have to be at the frontiers Something about why here at OECD: Going to talk about a new initiative in CISE, reinventing the Internet First foray into international waters….
  • We all know this remarkable story of the Internet -- in 20 years or less, the Internet has transformed our society -- the way we communicate, learn, conduct research and business, entertain ourselves and so on. It has been an engine for economic growth as well as enabler of S&E research and education. The study by National Academy of Engineering in year 2000 recognized the Internet as one of the top 20 engineering innovations that has transformed society. The research communities and federal agencies have played an important role in the research and development of Internet. It is one of our major success stories. BTW I am using the term Internet broadly -- not just IP layer but the whole Internet stack including WEB. Note in late 80s Internet was an obscure network used by the research community and today it is a critical infrastructure. It is important to note that In 1989 a router bug brought down the Internet and caused inconvenience to a few thousand researchers. In 2003 the SLQ slammer attack grounded airline flights, brought down thousands of ATM machines and caused more than a $B loss.
  • I like Drivers more than Motivation We have to recognize that Internet has been able to extend quite well for the past 30 years but now it is reaching its limits -- we can talk about the specific examples and that lead into the next bullet that is new opportunities enabled by technologies and applications.
  • It would be nice if we could discover and implement independent fixes for current Internet limitations, e.g., the security fix, the management fix, the availability fix, etc. But these dimensions need to be harmonized and work in concert; many trade-offs; thus, we need to experiment with new architectures that incorporate security, end to end models for mobile data, location-aware networking techniques, etc., etc. That is why we are proposing to build a shared facility that will allow for these kinds of experiments to be done over the next decade.
  • Today, such a large-scale experimental infrastructure does not exist. Historically, NSF has funded basic research, prototypes and small-scale testbeds. If we are going to experiment on creating and evaluating a new Internet, we need a large experimental infrastructure, such as we conceptualizing for GENI
  • Conceptual framework to show how o multiple network arhictectures can be supported on a single physical infrastructure o user opt-in can work To overcome the testbed dilemma
  • Preplanning activities include supporting research as well as smaller scale experimental testbeds. Both GENI Research and Facility are building on solid foundations.
  • The future Internet will be able to incorporate all kinds of new technologies – wireless, sensors, etc. While providing the highest level services that are secure, ubiquitous, robust, reliable, etc, Thus allowing for societal-level applications, such as e-science, digital living, and critical infrastructures, to be useful and beneficial to all
