Book on Performance Modeling and Analysis of Communication Networks
The text book is published as open access book by the Würzburg University Press: https://www.performance-modeling.org/
The book focuses on the fundamental models of queueing theory as well as advanced models for recent communication systems and networks. It gives an introduction in common methods of performance modeling and analysis of communication systems. These methods form the basis of traffic engineering, teletraffic theory, and system analytical dimensioning tools. The fundamentals of probability theory, stochastic processes, Markov processes, and embedded Markov chains are presented. Basic queueing models are described with applications in communication networks. Advanced methods are presented that have been frequently used in practice, especially discrete-time analysis algorithms, or which go beyond classical performance like quality of experience or energy efficiency. Recent examples of modern communication networks include Software Defined Networking or the Internet of Things. Throughout the book, illustrative examples are used to provide practical experience in performance modeling and analysis.
An implementation of the models in the book is available as interactive notebooks. The scripts will help students to better understand the impact of parameters on performance characteristics, will avoid common pitfalls in the implementation, and provide means for numerical robust and efficient implementations for researchers in the domain.
Short CV
Tobias Hoßfeld is professor at the Chair of Communication Networks at the University of Würzburg, Germany, since 2018. He finished his PhD in 2009 and his professorial thesis (habilitation) "Modeling and Analysis of Internet Applications and Services" in 2013 at the University of Würzburg, where he was also heading the "Future Internet Applications & Overlays" research group. From 2014 to 2018, he was head of the Chair "Modeling of Adaptive Systems" at the University of Duisburg-Essen, Germany. He has published more than 100 research papers in major conferences and journals, receiving several best conference paper awards, 3 awards for his PhD thesis, and the Fred W. Ellersick Prize 2013 (IEEE Communications Society) for one of his articles on QoE. He is member of the editorial board of IEEE Communications Surveys & Tutorials, Springer Quality and User Experience, ACM SIGMM Records and elected chairperson of the ITG/VDE expert group "Communication Networks and Systems" within the German society of Information Technology (ITG).
