In this paper we study the performance trade-off of access rate
control in high speed networks
by spectral analysis. The emphasis is placed on the interrelationship
between access control
queueing and network queueing, as affected by degrees of control in
response to differing input
power spectrum. Both deterministic and stochastic analyses are
developed. While the simple
deterministic analysis helps us to gain a good engineering insight
into access rate control in
high speed networks, the stochastic analysis provides us quantitative
measures of the access
rate control in random traffic environment. Interesting observations
are made between control
performance and low-frequency input statistics. In the stochastic
analysis we are able to derive
the exact solutions of a network queue fed by a correlated source
under the leaky-bucket access
control.
