This describes the files containing the DRAFT NSF Interagency Interim
NREN Implementation Plan. Since the Interagency Interim NREN is based
on the evolution of the existing Federal Agencies' research and
education networks (e.g. ESnet, NSI, NSFNET, and TWBnet) this document
may prove to be valuable background reading when contemplating NSF's
next NSFNET Backbone services solicitation in addition to the NSFNET -
NREN realtionship and subsequent plans. The original set of these
documents can be acquired via FTP from EXPRES.CISE.NSF.GOV.  For the
FTP session please log in as anonymous and use your e-mail address for
the password. Once logged in change directory to recompete ("cd
recompete").  We have included three versions of the Plan: a postscript
version with embeded figures (which doesn't work on many Apple
LaserWriters), an ascii version (we strongly recommend the
postscript version), and a postscript version without the figures
embedded (they are found in the directory as separate postscript
files). Compressed versions of the files are in the same directory.

Note:  It *may* be possible to print the impl.ps file on a LaserWriter
II if you submit it as the first job after restarting the printer.
