I'm looking for information on commercially available fiber-based LANs. The main criteria are: 1) 100 Megabit or greater bandwidth; 2) availability of a VME bus interface with reasonable buffering and performance. If you have first-hand info or pointers, please send email; I will post a summary if possible. David Anderson anderson@charming.berkeley.edu

I don't have any first hand experience, but two companies have come knocking at my door recently. The first is CANSTAR with their HUBNet stuff. It's 100MB in a fiber star configuration. It runs just under $10,000 when you figure in the cost of the star coupler. The other is ULTRANet. This is a somewhat faster and much more expensive unit primarily designed to connect frontends to their supercomputers. They give you a whole stack of UNIX software that interfaces between a psuedo- socket library and their funky units. They began their talk by quoting Chesson as gospel, not fully aware that his comments on TCP/IP protocol processing were disproved. Of course, if you only want 80Mbits, there is Proteons fiber optic ring. Ours wasn't too reliable, but we were one of the first to get it. I've moved on to another job from the one I was using that for, so I can't tell if it got better. Proteon is dirt cheap. -Ron

There is a 100 Mbps FDDI implementation available now. It is
presently VME based and has been demonstrated in a three node
MASSCOMP network and in a digitized voice and data demonstration.
