Mathematical methods based on the theory of stochastic processes have long been used effectively in telephone traffic modelling. Modern network traffic, which is distinctly different from traditional voice traffic, generates challenging problems of a mathematical and statistical character. Stochastic Modelling in Broadband Communications Systems provides students and professionals in telecommunications and computer engineering, who may have varying levels of mathematical backgrounds, with an overview of stochastic models and mathematical techniques meant to enhance their understanding of communication systems. For students and professionals working in probability and applied mathematics, the book serves an as introduction to a huge area of interesting problems and models arising from modern developments in broadband channel transmission systems.
