LOCAL AREA NETWORK DESIGN

---

The coming into use of wide-band local area networks in the late 1970s was a signal event in the development of the computer field. These networks were developed by computer engineers who perceived that the use of computer techniques, rather than telecommunication techniques, would permit the attainment of high bandwidth, low error rate, and low cost. As the authors of this book point out, the new wide-band local area networks came just when they were needed to enable the low cost computers then being installed in large numbers to share peripherals; at the same time they made possible a new approach to the design of shared computer systems.

The Ethernet represented original thinking. Rings had been discussed in the literature for some time, but fears about reliability held back practical developments. The construction of the Cambridge Ring was an act of faith in the reliability of TTL MSI packages - an act of faith which was wholly justified by results.

Local area networks are introduced in this book as fast communication systems; they can equally be regarded as slow computer buses. A typical local area network is roughly three orders of magnitude faster than an ordinary telephone line and one order of magnitude slower than the Synchronous Backplane Interconnection in a VAX-11/780. For comparison, a jet aircraft is about two and a half orders of magnitude faster than a bicycle.

It is clear that the development of local area networks still has a long way to go. This is especially true of rings, a subject about which the present authors are uniquely qualified to write. I welcome this book as a timely contribution to the literature.
