ABSTRACT
Considering the widespread influence of Ethernet, a
surprising amount of confusion exists concerning
various important aspects of its design. Our
objective in writing this paper is to spare future
designers of local area networks the searching and
speculation in which we were forced to engage.
We begin by describing the policies common to
Ethernet-like systems and by using an analytic
model to study their behavior. We then precisely
describe the mechanisms used in Ethernet itself,
exploring its detailed behavior by means of a
simulation model. Results from the two models, and
particularly from their comparison, provide insight
