The classic paper by Boggs, Mogul and Kent still stands. At
that time, in the mid eighties, there were many nay sayers.
Also, there were many erroneous chip set implementations to
the algorithms. In CSMA/CD media, ie. shared, there are still unresolved problems, one is known as the "capture effect" and there are methods to completely resolve that issue. To construct CSMA/CD networks today with hundreds of stations is quite foolhardy, especially since the HW
implementations can now keep up with the speed of the media. In 1988, not many chip-sets could do that at even 10 Mbps; today, 1GE chip sets can. All 1GE networks I have
ever seen or heard about are point-to-point 2 station networks and most modern 10, 100 networks are that way also.
I fail to see the need to rehash a decade of technology
implementation and developments in the IEEE802.3 suite, nor
discuss and analyze poor deployment practices including the
purchase of a multi-port repeater at Staples for $10 and gang them together to support hundreds of stations.
Point-to-point 10 GE implementations, full-duplex, will be used in the LAN,MAN and WAN, just as 100Mbps and 1GE is done
today, all with great success, low cost and simplicity. |
