Introduction
Mr. Chairman, members of the subcommittee, thank you for allowing
me the opportunity to testify on the National Science Foundation's
role in fostering the next stages of the information revolution.
I am pleased to be here today. This is a topic of utmost importance
for the future of our nation's economy and the well-being of our fellow
citizens. A healthy, long-term federal investment in high speed networking
and information technology overall is critical if the United States
is to remain a world leader - not only in science and engineering
- but in our economy, national security, health care, education and
overall quality of life.
My prepared remarks today will include a short history of NSF's support
for cutting edge concepts in high-speed networking and their transfer
to the private sector along with a brief discussion of the following
topics:
 |
NSF's participation in the multi-disciplinary
Federal Information Technology Research and Development Initiative
(IT R&D) for which NSF is the lead agency; |
 |
NSF's participation in the Next Generation Internet
Program - an integral component of the IT R&D initiative - our
cooperation with private industry through the rich transfer
of new ideas to the private sector, our cooperation with the
other NGI agencies; |
 |
NSF's efforts to promote connectivity and access
for all, including our efforts to improve connectivity for rural
and minority-serving institutions and our strong support for
cutting-edge education activities designed to ensure that our
citizens will have the scientific, mathematical, engineering,
and technological expertise needed to excel in tomorrow's knowledge-based
economy.

NSF Support for High-Speed Networking: A Record of Accomplishment
Mr. Chairman, this subcommittee has long been a strong, bipartisan
supporter of the federal investment in IT R&D. In the early 1980's,
this subcommittee strongly encouraged NSF to invest in high-performance
computing resources for the nation's academic scientists and engineers.
The subcommittee also was a leader in the enactment of the High Performance
Computing Act of 1991. This leadership continued with the passage
of the bipartisan Next Generation Internet Act of 1998.
With this backing from the subcommittee and the entire Congress, NSF
has continued to support some of the most successful and innovative
computer-communications concepts and technologies at their earliest,
most experimental stages. NSF funded university-based supercomputer
centers in the mid-1980's to provide academic scientists and engineers
with access to state-of-the-art computing power.
To facilitate access to the centers, NSF began a parallel effort in
networking. It built on fundamental investments by DARPA in a more
restricted environment, and resulted in the formation of the national
NSFNET backbone network and regional networks connecting university
students and faculty to the supercomputing centers. In a very brief
period of time, NSFNET and the regional networks began performing
important communication and information access functions in addition
to supercomputer center access. Through this development and its subsequent
privatization, the Internet industry was born.
Mr. Chairman, the story of NSF's longstanding support for backbone
networks is now well known but it is only one example of how fundamental
IT investments by NSF and other agencies have paid huge dividends
for the nation. Support of fundamental networking research has received
less publicity but is equally important to the future of information
science and technology.
For example, it was David Mills, an NSF grantee at the University
of Delaware, who made it possible to have one Internet as opposed
to a Tower of Babel of competing electronic networks. Mills developed
the first widely-used Internet routers -- the gateways and switches
that guide the bits and bytes of data around the globe at the speed
of light. That's why many people say NSF put the "inter"
in Internet. Today CISCO Systems - the premier maker of Internet router
technology - now has a market capitalization of $454 billion dollars.

Knowledge Transfer Not Just Technology Transfer
Innovations like the Internet router only occurred through sustained,
long-term federal investments in information science and engineering
by many agencies. One might think that these past successes assure
us of an equally bright future. Unfortunately, in a fast paced, technologically-rooted
information age, the worst thing we could do is rest on our laurels.
The key point is that the IT R&D conducted by private industry - be
it performed by large or small firms - is now primarily near-term
and product-focused. There are many reasons for this trend. With increased
global competition, increasingly rapid product cycling and high expectations
from shareholders, IT industry managers tend to focus on activities
that maximize short-term payoffs. Market pressures are often too great
and technology changes too rapid to allow for major investments with
a long-term perspective.
When the subject of technology transfer is brought up, there is one
aspect of the impact of basic research that is often overlooked -
the role of NSF's investments in people. NSF's Engineering Directorate
recently sponsored a set of studies on today's leading technologies:
areas like cell phones, fiber optics, and computer assisted design.
It's well known that the great majority of the seminal work in these
areas was performed by private industry--at labs like Corning, AT&T,
and Motorola.
Does that mean that NSF had no role? Hardly. When you go back and
look at the work, a clear pattern emerges. Scientists and engineers
who went to graduate school on NSF fellowships and research assistantships
often brought the key insights to industry. In a number of cases,
they became the entrepreneurs who created new firms and markets.
To quote from the study--"NSF emerges consistently as a major--often
the major, source of support for education and training of the Ph.D.
scientists and engineers who went on to make major contributions...."
It is this transfer of people - the highly trained scientists and
engineers supported by NSF and other agencies - that is making a tremendous
impact on our knowledge-based economy.
The NGI program is a tremendous success in this regard. In a preliminary
review of the NGI program, the President's Information Technology
Advisory Committee (PITAC) found that numerous NGI-funded scientists,
engineers and students - first funded at universities - have gone
on in just a few short years to found start-up companies with an estimated
market capitalization of over $27 billion.
Information Technology Research (ITR)
The impact of information technology on our society has been much
wider and much more pervasive than anyone could have anticipated just
a few years ago. Advances in computing, communications, and the collection,
digitization and processing of information have altered the everyday
lives of all our citizens.
There is no question that as Internet growth has gone through the
roof, IT has become the essential fuel for the nation's economic engine.
Even the ever-cautious Fed Chairman Alan Greenspan has pointed to
innovations in IT as the driving force behind our strong economic
growth.
The numbers speak for themselves. As Neal Lane has mentioned, more
than a third of our economic growth in the past five years has resulted
from Information Technology. IT investments have spurred an enormous
upswing in worker productivity that has fueled the current economic
boom. The challenge now is to sustain this record of success.
Last year, the PITAC concluded that federal support for long-term
research on information technology has been "dangerously inadequate."
In its words "support in most critical areas has been flat or
declining for nearly a decade, while the importance of IT to our economy
has increased dramatically." This has led to the government-wide
initiative in Information Technology R&D for which NSF is the lead
agency.
The Information Technology Research Initiative at NSF will emphasize
research and education on a broad range of topics. Focus areas include:
 |
Advancing computer system architecture;
research on software, hardware, system architectures, operating
systems, programming languages, communication networks, as well
as systems that acquire, store, process, transmit, and display
information. |
 |
Improving information storage and retrieval;
research on how we can best use the vast amount of information
that has been digitized and stored. |
 |
Connectivity and access for all;
research that aims to overcome the digital divide separating
the information "haves" from the "have-nots"
and research on inequality of access to and use of computing
and communications technology. |
 |
Scalable Networks of Embedded Systems;
As the scale of integration of systems that may be achieved
continues to grow, systems must be designed with both hardware
and software aspects treated from a unified point of view. |
 |
Novel approaches; new models of
computation and physical processes such as molecular, DNA and
quantum computing. These efforts are deeply anchored in the
mathematical and physical sciences and the biosciences.
|
Through our part of the multiagency IT R&D program, the Information
Technology Research (ITR) initiative, NSF will seek to strengthen
Education in IT, including:
 |
programs that provide scholarships,
fellowships and traineeships; |
 |
improved undergraduate research participation; |
 |
encouragement of graduate students
to participate in K-12 education; and develop new curriculum;
and |
 |
research aimed at understanding the
causes of underrepresentation of various segments of society
in the workforce.
|
NSF will also increase research on Applications of IT across fields
of science and engineering. This will also be a critical component
of the ITR initiative. This includes simulation to tackle research
problems across the frontiers of science and engineering. Important
networking applications include:
 |
Collaboration Technologies |
 |
Digital Libraries |
 |
Distributed Computing |
 |
Remote Operations and |
 |
Security and Privacy issues
|
Finally through the ITR Initiative, NSF will increase it's support
for Infrastructure including the Next Generation Internet Program.
Support for infrastructure will include:
 |
computing facilities ranging from
single workstations to clusters of workstations to supercomputers
of various sizes and capabilities; |
 |
large databases and digital libraries,
the broadband networking, data mining and database tools for
accessing them; |
 |
appropriate bandwidth connectivity
to facilitate interactive communication and collaboration and
software to enable easy and efficient utilization of networked
resources; and |
 |
networks of large and small physical
devices.

NGI Connections at NSF: A Tremendous Success
Mr. Chairman, the NGI program has been a great success. Enabled by
fundamental advances in optical networking under supported by DARPA
and NSF, the number of very high performance networks has increased
and the available bandwidth for research and education has had phenomenal
growth. A diverse array of US universities in all 50 states now have
high-speed connectivity thanks to NGI investments. In fact, many more
institutions than originally anticipated now have high-speed access
thanks to the program. Connectivity to Alaska and Hawaii has improved
dramatically as well.
NSF's original goal under the NGI program was to connect 100 universities
using the vBNS network and the Internet2 Coalition's Abilene network.
Today NSF is excited that over 170 university connection awards have
now been made. This includes over 40 universities in EPSCoR states
- nearly one-quarter of the total.
This increase in connectivity has resulted in interest in high performance
networking in both academia and industry. It has had enormous impact
on the knowledge transfer I mentioned earlier. Having so many more
scientists, engineers and students from across the nation involved
in high-speed networking activities has dramatically increased the
available talent pool for industry.
Universities form a rich, fertile proving ground for new network ideas
and concepts that can be quickly transferred to the private sector.
Without consistent federal funding, such a well-spring of ideas could
run dry.
What's Next for NGI: The Next-Next Generation Internet
In marking our 50 th anniversary, we are celebrating vision and foresight.
The recently retired hockey-great, Wayne Gretzky, used to say, "I
skate to where the puck is going, not to where it's been." Mr.
Chairman, at NSF, we try to fund where the fields are going, not to
where they've been. We have a strong record across all fields of science
and engineering for choosing to fund insightful proposals and visionary
investigators. It is our job to keep all fields of science and engineering
focused on the furthest frontier. Our task is to recognize and nurture
emerging fields, and to support the work of those with the most insightful
reach. And, we prepare future generations of scientific talent. In
this tradition, NSF is looking at new directions for the NGI program.
One trend is clear: high-speed fiber backbone networks are rich seed
beds for new capabilities. Now that connectivity has been dramatically
increased, new fundamental research problems must be tackled. In today's
networked world, dramatic increases in backbone speed do not automatically
translate into dramatic increases in performance. Many of these problems
will not be easily solved without new, novel approaches. Today, achieving
high performance from end user to end user - the so called Broadband
Last Mile Problem - remains difficult. Some commentators have remarked
that the current situation is like having a four-lane highways beginning
and ending with dirt roads. To increase backbone speed, efficiency
and stability, we will need fundamental research into new middleware
network service capabilities. This includes research in user authentication
and verification, distributed computing services, and distributed
storage services. Also, NSF will support research dealing with satellite
and other wireless technology to help reach into areas where wireline
and fiber are not possible or practical. We will also need research
into new optical access technologies. In the future optical backbones
will use more and more optical routing. Research is needed to discover
how to appropriately extend the reach of these technologies. This
will correspondingly extend the reach of networks and ensure that
institutions not now taking advantage of high performance networking
have the opportunity to do so.
Bridging the Digital Divide
This brings me to my last point. Today we find ourselves on a precipice--looking
down into that worrisome gap known as the digital divide. We are all
here today because we believe in the power of information technology
to bring about the most democratic revolution in literacy and numeracy
the world has ever known. We also know that if we're not careful,
this same power could be economically divisive. We imagine universal
connectedness, with talk of "tetherless networks" that anyone
could tap into anytime, anywhere. But we could also broaden the gap
between the information rich and the information bereft. In our own
nation, sociologists have identified groups whose access to telephones,
computers, and the Internet lag far behind the national averages.
These information gaps appear among nations as well. Most of those
who live in the Third World have never used a telephone. Our worldwide
web is a thinly stretched one. Less than two percent of the world
is actually on the web. If we subtract the United States and Canada,
it's less than one percent. The report by the President's Information
Technology Advisory Committee (PITAC) spells out some of these gaps.
"For instance," says the committee, "whites are more
likely than African-Americans to have Internet access" at home
or work. "We expect there are similar gaps with other minority
groups, such as Hispanics and Native Americans. Recent research...suggests
that the racial gap in Internet use is increasing." In September
1999 NSF made a four-year $6 million award to EDUCAUSE to help minority-serving
institutions develop campus infrastructure and national connections.
The award addresses Hispanic, Native American, and Historically Black
Colleges and Universities. The scope includes:
 |
Executive awareness, vision, and planning |
 |
Remote technical support centers |
 |
Local network planning |
 |
Local consulting and training |
 |
Satellite/wireless pilot projects |
 |
New network technologies: Prototype
installations |
 |
Grid applications
|
Conclusion
To conclude Mr. Chairman, let me again thank you for holding this
hearing so that we may exchange views on the future direction of this
important area. Let me also restate NSF's willingness to work with
you, the subcommittee and the full committee to ensure a robust federal
IT investment including the NGI program. The PITAC report has raised
important concerns over our lack of federal investment in fundamental
IT research and we at NSF are responding to the challenge. We look
forward to extending the federal IT partnership to help ensure U.S.
world leadership in IT. Thank you. |
