Computer Networks: Priming For High-Speed Applications

The High Performance Computing Act, which became law last December, provides a boost in federal funds to improve and integrate the confusing collection of computer networks used by scientists to transmit data and electronic mail. The ultimate goal is to create a high-speed national computer network, analogous to the interstate highway system, with a capacity to transmit data at one gigabit (1 billion bits) per second, a speed 700 times greater than today's system. Such a system would provide e

Such a system would provide enough data transfer capacity to allow supercomputers to effectively converse or for multimedia video conferencing to take place. Proponents argue that federal investment in high-speed networking for scientists will be a key to United States competitiveness in the information age.

The National Science Foundation and the Defense Advanced Research Projects Agency (DARPA) have been designated the lead agencies to create, in collaboration with five other government agencies, the gigabit network, to be called the National Research and Education Network (NREN). And, to that end, federal support for networking rose from $65 million in 1991 to $93 million in 1992 and is to be funded at a proposed $123 million in 1993.

Freeman Gilbert, a seismologist at the Scripps Institution of Oceanography in San Diego, Calif., says gigabit networking will offer new ways to conduct research in many fields. Citing an example, Gilbert says, "It's not ...
