We will be putting in an ethernet soon; it may have to span several
buildings. I had heard that this may present problems. I would like to
hear from people who have multi-building ethernets, so I know what kind of
chance I am taking.

We run our rather large ethernet between several buildings here at the University of Texas without a major problem. Currently we have a backbone cable running between the CS department and the Computation Center. This cable spans three buildings. Off of this cable we run several other ethernet cables connected by repeaters and remote repeaters to several other buildings on campus. This configuration kind of stretches the original intent of an ethernet, but seems to work fairly well. Eventually we plan to install a broadband backbone cable between the buildings and use ethernets within single buildings only. I have heard of ground potential problems with running the cable between buildings. So far we have experienced no problems with ground loops or other such nasty phenomena.

You may want to look at a new product announced by DEC called LAN Bridge 100 that allows you to connect multiple ethernets together. They can be electrically isolated with a fiber optic link up to 2000 meters, traffic that is local to one ethernet does not get sent to the other ethernet unless that's where the destination is, to the systems it looks like one big ethernet, and you can link up to seven ethernets with bridges. It is also protocol independent. -- Rich Kotter decvax!decwrl!muscat!kotter

Free advertising on the net again...
Bridge also has a similar product, and I don't believe it's limited
to 2000 meters either.
