Spectral Analysis of Access Rate Control in High Speed Networks

Abstract

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.
