Ethernet has been the core networking technology since the early 1980s, and is used by every high-tech business. While the basic protocols have changed little, new options such as Fast Ethernet and Gigabit Ethernet have increased the complexity of the topic. Ethernet: The Definitive Guide provides everything you need to know to set up and manage an Ethernet network. Ethernet: The Definitive Guide includes details about the IEEE 802.3 standard and its protocols, and is separated into five parts: Introduction to Ethernet provides a tour of basic Ethernet theory and operation, including a description of Ethernet frames, operation of the Media Access Control (MAC) protocol, full-duplex mode, and Auto-Negotiation. Ethernet Media Systems is the heart of the book. This section shows you how to build media-specific Ethernet networks, from a basic 10BASE-T Ethernet offering 10 Mbps over twisted-pair cables, to an advanced 1000BASE-X Gigabit Ethernet system, providing up to 1 Gbps of data transfer over fiber optic cables. Building Your Ethernet System teaches you how to build twisted-pair and fiber optic media segments, as well as how to expand the reach of your local area network using repeaters and switching hubs. Performance and Troubleshooting is divided into two chapters. The first describes the performance of a given Ethernet channel, as well as the performance of the entire network system. The second chapter includes a tutorial on troubleshooting techniques and describes the kinds of problems; network administrators are likely to encounter. The last part of the book, Appendixes, includes a complete glossary of terms used throughout the book, a resource list, descriptions of thick and thin coax-based Ethernet systems, and a guide to AUI equipment installation and configuration. Ethernet: The Definitive Guide is the one essential source of information for network administrators who need to build and manage scalable local area networks.

This edited volume presents the proceedings of the AMAA 2015 conference, Berlin, Germany. The topical focus of the 2015 conference lies on smart systems for green and automated driving. The automobile of the future has to respond to two major trends, the electrification of the drivetrain, and the automation of the transportation system. These trends will not only lead to greener and safer driving but re-define the concept of the car completely, particularly if they interact with each other in a synergetic way as for autonomous parking and charging, self-driving shuttles or mobile robots. Key functionalities like environment perception are enabled by electronic components and systems, sensors and actuators, communication nodes, cognitive systems and smart systems integration. The book will be a valuable read for research experts and professionals in the automotive industry but the book may also be beneficial for graduate students.

PROFINET ist der erste durchg?ngige Industrial Ethernet-Standard f?r die Automatisierung. Der Einsatz von TCP/IP erlaubt eine offene Kommunikation von der Unternehmensleitebene bis in den Prozess. PROFINET IO erm?glicht eine besonders schnelle Real Time-Kommunikation zur ?bertragung von Prozessdaten. Dies entspricht den heutigen Anforderungen an dezentrale Applikationen. Bereits installierte Feldbusse wie PROFIBUS, INTERBUS oder DEVICENET lassen sich dabei ?ber sogenannte Proxies integrieren. Die taktsynchrone Kommunikation bei hochperformanten Motion Control-Anwendungen ist mit isochronem Real Time (IRT) realisierbar. PROFINET CBA teilt komplexe Anwendungen in ?berschaubare und autonom arbeitende Einheiten auf. Auch hier ist die Integration bereits bestehender Feldbussysteme wie PROFIBUS und AS-Interface ?ber Proxies auf einfache Weise m?glich. So k?nnen einzelne Anlagenteile separat und hersteller?bergreifend entwickelt und getestet werden, bevor sie in Betrieb genommen und in eine Gesamtl?sung integriert werden. PROFINET setzt auf etablierte IT-Standards f?r Netzmanagement und Fernwartung und bietet ein speziell auf die Automatisierungstechnik zugeschnittenes Security-Konzept. Detailliert werden neben den n?tigen Grundlagen die beschriebenen Real Time-Konzepte mit den Programmierschnittstellen erl?utert. Eine Zusammenfassung der PROFINET-Netzwerkger?te und m?glichen Vernetzungsvarianten mit Hinweisen zu Projektierung und Inbetriebnahme runden das Gesamtkonzept ab. Neu aufgenommen wurde f?r diese zweite Auflage auch ein Einblick in die Sicherheitstechnik unter PROFINET mit dem Profisafe-Profil. Dieses Buch bietet einen Einstieg in die neue PROFINET-Technologie. Entscheider und Anlagenplaner, Sch?ler und Studenten erhalten einen kompakten ?berblick ?ber das Konzept, die Grundlagen und aktuelle Ger?te. Projekteure, Inbetriebnehmer und Techniker erhalten umfangreiches Wissen zur Planung und L?sung eigener PROFINET-basierter Automatisierungsaufgaben. Technische Zusammenh?nge und praktische Anwendungen werden anhand von SIMATIC-Produkten beschrieben.

This unique book offers a vendor-neutral approach for designing large local area networks according to business or organizational needs, rather than from a product perspective. Author and independent network design consultant Kevin Dooley outlines "top-down network design" for building a technological infrastructure to fit your organization's requirements, a process far more effective and cost-efficient than fitting the organization to the parameters of a shrink-wrapped proprietary solution.Dooley argues that the design of a network is largely independent of the products used. Whether you use a Cisco or Juniper router, the same security issues and protocols apply. The questions he addresses in this book are need-specific: Do I use a router or a switch? Should I route between switched areas or switch between routed areas?Designing Large-Scale LANs covers everything from security, bandwidth and scalability to network reliability, which includes backup, redundancy, and points of failure. Specific technologies are analyzed in detail: network topologies, routing and switching strategies, wireless, virtual LANs, firewalls and gateways, security, Internet protocols, bandwidth, and multicast services. The book also discusses proprietary technologies that are ubiquitous, such as Cisco's IOS and Novell's IPX.This complete guide to top-down network design will help you choose the right network solutions. If you're designing large scale networks and need expert advice and guidance, look no further than Designing Large-Scale LANs.

Zuverlässige Vorhersagen sind doch möglich! Nate Silver ist der heimliche Gewinner der amerikanischen Präsidentschaftswahlen 2012: ein begnadeter Statistiker, als »Prognose-Popstar« und »Wundernerd« weltberühmt geworden. Er hat die Wahlergebnisse aller 50 amerikanischen Bundesstaaten absolut exakt vorausgesagt – doch damit nicht genug: Jetzt zeigt Nate Silver, wie seine Prognosen in Zukunft Terroranschläge, Umweltkatastrophen und Finanzkrisen verhindern sollen. Gelingt ihm die Abschaffung des Zufalls? Warum werden Wettervorhersagen immer besser, während die Terrorattacken vom 11.09.2001 niemand kommen sah? Warum erkennen Ökonomen eine globale Finanzkrise nicht einmal dann, wenn diese bereits begonnen hat? Das Problem ist nicht der Mangel an Informationen, sondern dass wir die verfügbaren Daten nicht richtig deuten. Zuverlässige Prognosen aber würden uns helfen, Zufälle und Ungewissheiten abzuwehren und unser Schicksal selbst zu bestimmen. Nate Silver zeigt, dass und wie das geht. Erstmals wendet er seine Wahrscheinlichkeitsrechnung nicht nur auf Wahlprognosen an, sondern auf die großen Probleme unserer Zeit: die Finanzmärkte, Ratingagenturen, Epidemien, Erdbeben, den Klimawandel, den Terrorismus. In all diesen Fällen gibt es zahlreiche Prognosen von Experten, die er überprüft – und erklärt, warum sie meist falsch sind. Gleichzeitig schildert er, wie es gelingen kann, im Rauschen der Daten die wesentlichen Informationen herauszufiltern. Ein unterhaltsamer und spannender Augenöffner!
