This thesis deals with simulation of a conflict-free token-passing protocol
for local area bus networks. The primary emphasis of this simulation study
is to observe the effects of token holding time on the performance of the
network. Token holding time is adjusted to account for three types of
service disciplines: purely non-exhaustive, non-exhaustive and exhaustive.
Network performance for these three service disciplines is compared to
determine, which one of the three gives a relatively better performance.
Besides throughput and delay, a more compact form of performance measure
called "power", has also been used in this study. Power is simply a ratio
of throughput and delay. This study has shown that the token holding time
has significant effect on the performance of a local area network.
Simulation results of this study, are presented in terms of throughput,
delay, power, logical ring size, token circulation time,
efficiency/overhead versus offered load and token holding time. Some
results are also presented in terms of histograms.
