Large Deviations for Gaussian Queues
Modelling Communication Networks
Chapter One
Introduction
Performance Analysis, Queuing Theory, Large Deviations. Performance analysis
of communication networks is the branch of applied probability that deals with
the evaluation of the level of efficiency the network achieves, and the level of
(dis)satisfaction enjoyed by its users. Clearly, there is a broad variety of measures
that characterize these two aspects. Focusing on the efficiency of the use of network
resources, one could think of the throughput, i.e., the rate at which the network
effectively works - in the case of a single network element, this could be the rate
(in terms of, say, bits per second) at which traffic leaves. Another option is to
use a relative measure, such as the utilization, commonly defined as the ratio of
the throughput and the available service speed of the netwo ... read full excerpt from Large Deviations for Gaussian Queues: Modelling Communication Networks ebook
