A WORD ON TERMINOLOGY
The expression "national research and education network" is taken to
mean "the U.S. National Research and Education Network" in the
material which follows. It is implicitly assumed that similar
initiatives may arise in other countries and that a kind of Global
Research and Education Network may arise out of the existing
international Internet system. However, the primary focus of this
paper is on developments in the U.S.
1. The NREN in the U.S. will evolve from the existing Internet base.
By implication, the U.S. NREN will have to fit into an international
environment consisting of a good many networks sponsored or owned and
operated by non-U.S. organizations around the world.
2. There will continue to be special-purpose and mission-oriented
networks sponsored by the U.S. Government which will need to link
with, if not directly support, the NREN.
3. The basic technical networking architecture of the system will
include local area networks, metropolitan, regional and wide-area
networks. Some nets will be organized to support transit traffic and
others will be strictly parasitic.
4. Looking towards the end of the decade, some of the networks may be
mobile (digital, cellular). A variety of technologies may be used,
including, but not limited to, high speed Fiber Data Distribution
Interface (FDDI) nets, Distributed-Queue Dua...
