Hello
I have read that DEC chose FDDI as our high-speed LAN technology,
among several other potential technologies.
Could someone tell me what these other technologies are. What are
their speed, topology, is any standards work being done etc...
Thanx

I can't think of any current alternative to FDDI that was seriously considered. FDDI was selected from a set of proposals years ago as the best option at the time for meeting bandwidth, throughput, cost, and standardization requirements. Since that time, DEC has been heavily involved in developing the various standards, technologies, and components, necessary to meet those requirements. I don't think that any serious work was done on any of the alternatives by anyone which would make them really competitive with FDDI. In the mean time, technology has continued to move on and now there is discussion of gigabit links, but those are not alternatives to FDDI, but complementary. The prime example is HPPI and DEC is involved this standard to ensure that it retains a minimum level of compatibility with 802 to ensure that it fits today's FDDI and 802.3 product strategy. I'm sure that if we were making the decision today, that we'd chose something different, but to suggest otherwise would imply that we haven't learned anything about FDDI or technology in general. Does this answer your question? | |||||

Yes, that was what I was looking for.
Thanx,

Scientific American May 1996 reports 1 trillion bits per second through a single strand of fiber optic. Apparently this was achieved using a relatively short piece of fiber and multiple lasers of different wave lengths. FDDI is 125 million bits per second raw. They're going 8,000 times faster here. Of course it might be a few years until we get products. | |||||
