A crucial step during the design and engineering of communication systems is the estimation of their performance and behavior; especially for mathematically complex or highly dynamic systems network simulation is particularly useful. This book focuses on tools, modeling principles and state-of-the art models for discrete-event based network simulations, the standard method applied today in academia and industry for performance evaluation of new network designs and architectures. The focus of the tools part is on two distinct simulations engines: OmNet++ and ns-3, while it also deals with issues like parallelization, software integration and hardware simulations. The parts dealing with modeling and models for network simulations are split into a wireless section and a section dealing with higher layers. The wireless section covers all essential modeling principles for dealing with physical layer, link layer and wireless channel behavior. In addition, detailed models for prominent wireless systems like IEEE 802.11 and IEEE 802.16 are presented. In the part on higher layers, classical modeling approaches for the network layer, the transport layer and the application layer are presented in addition to modeling approaches for peer-to-peer networks and topologies of networks. The modeling parts are accompanied with catalogues of model implementations for a large set of different simulation engines. The book is aimed at master students and PhD students of computer science and electrical engineering as well as at researchers and practitioners from academia and industry that are dealing with network simulation at any layer of the protocol stack.

Starting with Napster and Gnutella, peer-to-peer systems became an integrated part of the Internet fabric attracting millions of users. According to recent evaluations, peer-to-peer traffic now exceeds Web traffic, once the dominant traffic on the Internet. While the most popular peer-to-peer applications remain file sharing and content distribution, new applications such as Internet telephony are emerging.

Within just a few years, the huge popularity of peer-to-peer systems and the explosion of peer-to-peer research have created a large body of knowledge, but this book is the first textbook-like survey to provide an up-to-date and in-depth introduction to the field.

This state-of-the-art survey systematically draws together prerequisites from various fields, presents techniques and methodologies in a principled and coherent way, and gives a comprehensive overview on the manifold applications of the peer-to-peer paradigm. Leading researchers contributed their expert knowledge to this book, each in his/her own specific area.

Lecturers can choose from the wide range of 32 tightly integrated chapters on all current aspects of P2P systems and applications, and thus individually tailor their class syllabi. R&D professionals active in P2P will appreciate this book as a valuable source of reference and inspiration.

The refereed proceedings of the 10th International Workshop on Quality of Service, IWQoS 2003, held in Berkeley, CA, USA, in June 2003. The 27 revised full papers presented were carefully reviewed and selected from numerous submissions. The papers are organized in topical sections on analysis and modeling, resource allocation and admission control, multimedia and incentives, dependability and fault tolerance, routing, availability and dependability, Web services, rate-based QoS, and storage.

Dieser Buchtitel ist Teil des Digitalisierungsprojekts Springer Book Archives mit Publikationen, die seit den Anfangen des Verlags von 1842 erschienen sind. Der Verlag stellt mit diesem Archiv Quellen fur die historische wie auch die disziplingeschichtliche Forschung zur Verfugung, die jeweils im historischen Kontext betrachtet werden mussen. Dieser Titel erschien in der Zeit vor 1945 und wird daher in seiner zeittypischen politisch-ideologischen Ausrichtung vom Verlag nicht beworben.

The Industrial Information Technology Handbook focuses on existing and emerging industrial applications of IT, and on evolving trends that are driven by the needs of companies and by industry-led consortia and organizations. Emphasizing fast growing areas that have major impacts on industrial automation and enterprise integration, the Handbook covers topics such as industrial communication technology, sensors, and embedded systems. The book is organized into two parts. Part 1 presents material covering new and quickly evolving aspects of IT. Part 2 introduces cutting-edge areas of industrial IT. The Handbook presents material in the form of tutorials, surveys, and technology overviews, combining fundamentals and advanced issues, with articles grouped into sections for a cohesive and comprehensive presentation. The text contains 112 contributed reports by industry experts from government, companies at the forefront of development, and some of the most renowned academic and research institutions worldwide. Several of the reports on recent developments, actual deployments, and trends cover subject matter presented to the public for the first time.
