seeking opinions on a small tcp-ip university network
06 Oct 87 21:17:06 ADT

We are new to the TCP/IP world. We are planning to install a small
TCP/IP network within a University Engineering Building initially,
with growth to the whole campus expected long term. The current
situation looks like this within the Engineering Building:
-- The campus is wired with a typical broadband LAN cable, currently
   supporting RS-232 terminal access to various mainframe and
   minicomputers (SYTEK 2000 product) and PC-Network interconnection
   for IBM PC's.
-- Building site A contains IBM 3090 mainframe running MVS operating
   system and IBM PC/RT running BSD 4.3.
-- Building site B contains SGI IRIS 1400 and SGI IRIS 2400 graphics
   workstations running UNIX and an IBM PC/RT running BSD 4.3.
-- Building site C contains a MicroVAX II running ULTRIX and a
   Sun standalone workstation running Unix
-- Building site D contains a VAX running VMS
The following interconnection schemes are under consideration:
-- TCP/IP Ethernet over the existing broadband cable
-- Install Ethernet baseband cable in the building; the current
   sites would be at the upper distance limit of "thin wire" Ethernet,
   we believe, making true Ethernet cable the likely choice.
-- Install an Ethernet at each building site (each is "room sized"),
   either regular or "thin wire" and gateway/bridge/? over the
   broadband cable
-- Install Ethernet at each building site and install baseband "backbone"
   cable to gateway/bridge/? the Ethernets.
Any opinions or comments would be appreciated. Please reply via
electronic mail to the undersigned, and indicate if you think a
summary of responses would be of interest to the network.
