Teletraffic Models and Tools: From Basics to Advanced

Khosrow Sohraby (University of Missouri-Kansas City)

In this tutorial, we provide a unified and simple treatment of teletraffic models and their teletraffic analysis in computer and telecommunications networks. We first review the basic teletraffic models and their solution techniques. Then, in a systematic and simple manner, we extend the models to cover more practical and complex situations frequently encountered in modern networks. A unified and powerful solution methodology based on elementary concepts in linear system theory will be presented. This will cover common teletraffic models including discrete state Markov models, fluid-flow models, Brownian motion models, and structured Markov Chains frequently encountered in the teletraffic analysis of modern networks. To further clarify the concepts, the usage of the publicly available software package TELPACK (TELetraffic PACKage) will be demonstrated by using applications in high-speed networks and cellular systems.

Outline: -Poisson and Birth-and-Death (BD) Processes with applications -Generalization of Poisson Process (MMPP, MAP, etc.) and Quasi-Birth-and-Death (QBD) processes with applications -Structured Markov Chains with applications in ATM networks -Fluid-flow and Brownian motion models and their solution -Other models (Time-series, long-range dependent, heavy-tailed, self-similar) -Using TELPACK in basic and advanced performance analysis

It is recommended that students have some basic background of probability and Markov chains.
