|Fascinating facts about Robert
AT A GLANCE:
Robert Metcalfe needed something that was fast, could
connect hundreds of computers and span the whole building, Something
like a local area network, which Metcalfe developed in a rudimentary
form in 1973 and dubbed Ethernet. The original Ethernet
sent roughly a paragraph of data over thick coaxial cable at a distance of

This survey of the Ethernet is enriched by the authors intimate knowledge of
its historical and developmental context. He glances through the original
1970s papers by Metcalfe in which the Ethernet was parameterized as well as
the unfortunate misunderstanding of Metcalfe's simple model of throughput,
and the subsequent papers that tracked performance characteristics and

WORDS OF WISDOM:
"Ethernet is the on-ramp for the Internet.
TCP/IP and Ethernet were both invented in the same year, and they both grew
up together." - Robert M. Metcalfe
HOW IT WORKS:
The term Ethernet refers to the
family of local-area network (LAN) products covered by the IEEE 802.3
standard that defines what is commonly known as the CSMA/CD protocol. Other
technologies and protocols have been touted as likely replacements, but the
market has spoken. Ethernet has survived as the major LAN technology (it is
currently used for approximately 85 percent of the world's LAN-connected PCs
and workstations) because its protocol has the following characteristics:

- Ethernet is by far the most widely
installed LAN, with connected computers numbering over 50 million.
- Robert Metcalfe shares four patents for
