Introduction -- Performance parameters, optimisation of resource use -- Model modules -- Load generators -- Operating modules -- Simulation of operating systems -- Simulation-based optimisation with AI.

The book combines internet modeling with the new programming language Julia. It demonstrates Julia's suitability for implementing established internet models and research-oriented topics such as car-to-infrastructure communication and black-box models for load predictions with neural networks. After studying the book and gaining inspiration for further independent analyses, the reader will be able to tackle even more complex modeling tasks in research and development using Julia. The contents Introduction Performance parameters, optimization, use of resources Model modules Load generators Queuing modules Simulation of queuing systems Simulation-based optimisation with AI The target groups Teachers and students (Master, PhD) Employees of research institutions Network managers The Author Ulrich Hofmann has over 30 years of experience in business, education and research, focusing on Internet technologies with an emphasis on Quality of Service (QoS). The translation was done with the help of artificial intelligence. A subsequent human revision was done primarily in terms of content. This book is a translation of an original German edition. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation.
