As should be evident, there was no one overwhelmingly superior technology. The numerous
studies conducted [7, 9, 10] on these LAN technologies were not conclusive on
the superiority of one over the other per se, at least from a technology and performance
standpoint; rather it appeared that any one of these could be made to look particularly
appealing when modeled with the right combination of parameters. For instance, the
token-based technologies performed better at higher loads than did Ethernet.
Despite not having any overwhelming technological superiority, or any significant
time to market advantage (all the IEEE standards were developed around the same
time and General Motors/IBM, having considerable market clout, actively backed the
token technologies), Ethernet has gone on to become, by far, the most successful and
widely deployed LAN technology in the world today. While Token Bus and Token Ring
have become nearly obsolete, Ethernet has had more than 2 billion ports deployed (estimates
from Dell??™Oro and other analysts), making it the standard interface for most
network-capable devices in the LAN today.
Domination in the Enterprise LAN
Ethernet has established itself as the overwhelmingly dominant technology in the LAN
market.
