30 Years of Ethernet

Babylon Rocker writes "An interview with one of the inventors of Ethernet." Metcalfe talks about the history of Ethernet as well as what he's been up to for the last couple years. (Not surprisingly, he's now a VC ;)

  1. TCP/IP by ciroknight · · Score: 2, Interesting

    Wait... if Ethernet has been around 30 years, that makes TCP/IP PRETTY DAMN OLD!!!!! Anyone up for re-inventing the wheel??? Maybe someone can make a protocol in which practically any piece of information can be traded, with a special way to commit a special pipeline to different medias (such as movie/music downloads getting a compressed, special set of ports used just for that purpose..).
    Next thing you know, the teleco's will be bringing up charges against us for inventing a better internet... when will this end!?!
    OR OR Or......... Maybe I'm delusional...

      I think it might be younger. I think the internet switched to TCP/IP around 1983.

      One indicator of this is that the relevant RFCs (791 and 793) are dated in 1981. At the time there were all kinds of long-haul data links, and lots of short-haul stuff too. I remember the University where I was an undergrad developing their own network to connect terminals to mainframes. Then they added X.25 capability so you could talk to people in other places (and boy was it expensive!). Then they hooked it up to the Internet. Then they ditched it completely, but not before several hacks to hook those new-fangled PCs up to it. At the time I considered myself fortunate to have a 9600 baud SLIP link.

      It's clear from the earliest RFCs that people really didn't know what computer networking was going to look like, and were making it up as they went along. People were certainly networking computers prior to the final form of TCP/IP; just that the present implementation of TCP/IP gelled the same year MTV went on the air.

      I've seen several different protocols that can be used over IP in actual use. Most were only used for specific applications. Generally bulk mainframe data transfers. TCP and UDP supply just about everything you could want though. The other protocols I mentioned could be implimented over UDP just as easially if anyone cared to. (Not TCP though, slow start and a few other network nice things are specificly not wanted - they assume the network bandwidth is fot one application)

    Wow. That was stupid, allright. At the time, what he said about Linux was obviously wrong, and stupid. In hindsight, it REALLY looks dumb.

    On the other hand, look at what he said about Windows:

    W2K is software also from the distant past -- VAX/VMS for Windows. But it will overpower Linux. NT, now approaching 23x6 availability, is already overpowering Linux.
    Snip out the parts about Linux, and you get

    This was unkind to Windows, but not totally untrue. I like ``VAX/VMS for Windows''.
  4. Xerox, Broadband by fm6 · · Score: 4, Interesting
    Two interesting bits of trivia. First, note that Xerox, which did all the early R&D for Ethernet, is mentioned only in passing. As with the GUI revolution and OOP, Xerox did all the pioneering, but dropped the ball when it came to actually profitting from it.

    Second, Metcalfe defines "broadband" to mean "high bitrate" rather than "uses a broad frequency band". Nitpickers like me have been quibbling over this change in definitions, but if someone like Metcalfe has gone over, it's time to let it drop!

    I've never done any fibre channel, but SONET is very not novel, and in fact it is a dying dinosaur. The only reason it is so widespread is tradition, and the ethernet has caught up bigtime; and is much, much cheaper.

    If I was a telephone company I would be looking at buying only VOIP equipment and run it on private LANs with plenty of bandwidth. No SONET at all.

  7. The "gigalapse" that wasn't by Anonymous Coward · · Score: 4, Interesting

    Bob Metcalfe once predicted that the internet would 'gigalapse' due to IP namespace exhaustion and sheer load. It didn't happen.

    Bob has made a career out of making an ass of himself with idiotic predictions coupled with a humongous ego. He fancied himself quite clever when he called the free software/open source movement "the open sores movement." Har har! You may have a career with ZDNET yet, Bob.

    Hey Bob we thank you for ethernet, but you're still a jerk.

  8. He still doesn't "get" open source. by nathanh · · Score: 4, Interesting

    He makes this rather ignorant comment:

    ... it is unlike open source in that competitors don't give their intellectual property away.

    Open source contributors who use the GPL never "give their intellectual property away". Copyrights are very strongly defended; the recent FSF vs OpenTV story is sufficient proof of this. Trademarks are very strongly defended: Linus and RedHat have both defended trademarks. Patents are a sticky mess but even then the GPL doesn't demand that you give up patents; only that you don't use them to restrict or impede licensing. The open source movement is not so stupid as to "give away" code. Strong ownership of intellectual property is at the very core of open source.

    The subtle but important distinction is that open source developers want to share their intellectual property. The philosophy is "you may use my IP if I can use yours". This is not giving anything away; it's building a community of cooperation. There is an exchange of value between two parties even though the exchange is not monetary.

    I suppose it's possible to argue that BSD zealots are giving their intellectual property away. Yet another reason to avoid the BSD license.

    An interesting quote from your linked to story:

    Why do I think Linux won't kill Windows? Two reasons. The Open Source Movement's ideology is utopian balderdash. And Linux is 30-year-old technology.

    Name a single networking infrastructure used more commonly than the 30-year-old ethernet!

    Why does this seem ironic to me?
