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.
