Businesses, Schools and U.S. Agencies to Join in Effort

By JOHN MARKOFF

The National Science Foundation plans to announce today that a large  
group of the nation's leading communications  and computer companies  
universities  and research laboratories and several Government agencies  
will begin development of a high-speed network that will allow computer  
data to be transmitted at speeds almost 700 times faster than possible  
over existing networks. It would be the first comprehensive attempt in  
the United States to advance the critical technological area of computer  
networks and is being called an important model for cooperation between  
business and government.

The widespread support for the computer network project stands in sharp  
contrast to the reception received by other recent cooperative projects  
in high technology such as the effort to finance research in high- 
definition television and the joint venture known as U.S. Memories, that  
was intended to strengthen the United States in the semiconductor  
business. Those projects have foundered for lack of money or enthusiasm  
among Government and business. In Japan, the government and large  
corporations have already begun work on high-speed computer networks,  
known as data highways, that enable the transmission of the equivalent  
of about 160 hefty novels every second compared with only about two  
novels every second in even the fastest networks today.

By conveying so much data so quickly, using the same optical-fiber  
cables now used by some long-distance telephone carriers, high-speed  
computer networks hold the promise of many new scientific and commercial  
uses , that could be available by the middle of this decade. These  
include the ability to transmit to and receive data from a hybrid of  
television and computer. The new device would have a picture and sound  
of movie-like quality and the capacity to allow the viewer to manipulate  
the images and data displayed on the screen and instantaneously exchange  
the information with other users.

Other potential uses that could evolve from the new project include  
three-dimensional medical imaging that allows doctors thousands of miles  
apart to analyze lifelike, high- resolution images; far more accurate  
understanding and prediction of weather and climate because of the  
ability to link the power of supercomputers around the country, and  
multimedia teleconferencing that would combine video images and computer  
data, allowing business meetings without the need to travel.

$100 Million From Companies

The data network is being initiated with $15 million from the National  
Science Foundation and from a Pentagon agency that has financed research  
in basic technology. But more than $100 million will come from  
companies. including the International Business Machines Corporation and  
the American Telephone and Telegraph Company, during the three-year  
project, executives at the foundation said.

The venture "marks an important step forward," said Robert B. Reich, a  
Harvard University economist. "There are a host of technological areas  
in which the United States is falling behind to which this model might  
be directly applicable if it means developing skills and insights in new  
technological areas," he said.

The computer-network project will draw together dozens of corporations  
and universities, including I.B.M. AT.&T., the MCI Communications  
Corporation, the regional Bell telecommunications companies and  
universities including the Massachusetts Institute of Technology, the  
University of Pennsylvania, the California Institute of Technology and  
the University of California at Berkeley. Government laboratories  
including those in Los Alamos, N.M., and Livermore, Calif. and the  
nation's five supercomputer centers will also participate.

A Pioneer's Brainchild

The project is the brainchild of Robert E. Kahn, a pioneer of the  
nation's first computer network experiment, called Arpanet, and David J.  
Farber, a computer scientist at the University of Pennsylvania. Mr. Kahn  
is president of the Corporation for National Research Initiatives, a  
computer technology research group in Reston, Va., that will receive the  
Government grant expected to be announced today.

Mr. Kahn was director of computer science research at the Defense  
Advanced Research Projects Agency, the Pentagon agency participating in  
the project. Mr. Kahn said that he would not comment on the project  
until it had been formally announced by the National Science Foundation.

Computer scientists said significant technical challenges remain to  
allow the transmission and reception of computer data at speeds above a  
billion bits per second, a goal of the new network.

Transmitting computer data is clone in a way similar to the way mail has  
traditionally been sorted in post offices, said William A. Wulf, a  
computer scientist at the University of Virginia. Postal employees read  
addresses and place envelopes in particular slots.

Similarly computer networks break data into packets, send them as  
strings of digital signals and then sort them when they arrive at their  
destination. The problem with very high speed networks, said Dr. Wulf,  
is that even the fastest machines that serve as gateways between the  
data highway and the computers they connect are not able to keep up with  
the stream of 1's and 0's possible with new networks. The challenge is  
therefore to develop a new class of ma- chines to serve as gateways.

The development project consists of five experimental networks.

The effort represents the first phase of a multi-year endeavor that  
supporters hope will ultimately create the national data highway.

Project developers said they are still uncertain about the cost of  
deploying a nationwide high-speed network. It is possible, they contend,  
that the rapidly increasing technology of long-distance optical-fiber  
networks may generates a surplus in capacity, permitting low-cost  
delivery of data and digital video services.

Support of Gore

"This represents a great example of how industry and government can work  
together to develop a key technology needed for the effective use of a  
national network of data super- highways soon to put in place," said  
Senator Albert Gore Jr., Democrat of Tennessee. "It's not a huge amount  
of money but if it will provide a great many useful applications for the  
network."


Senator Gore has introduced legislation that would finance the cost o  
developing a high-speed compute network to link the nation's super  
computer centers.

The Bush Administration has said it supports a national high-speed  
computer network but has not committed to backing new financing for the  
project.

One scientific project that will rely on the network will link a radio  
telescope array at the University of California at Berkeley with a Cray  
II supercomputer at the National Center for Supercomputer Applications  
in Champagne-Urbana, ILL., and computer work stations at the University  
of Maryland. Such a network would permit astronomers to use radio  
telescopes interactively in ways never before possible, said Larry  
Smarr, director of the supercomputer center.
