Data networks are telecommunications networks that are installed and operated for information exchange between data communication devices such as computers and voice gateways. Although data networks can transfer any type of digital media (voice, data or video), the type of network, services used and optional configurations can dramatically affect the performance of data services. This book provides a functional description of the key data network parts including hubs, routers, bridges and gateways. You will discover the differences between personal area networks (PANs), premises distribution networks (PDNs), local area networks (LANs), metropolitan area networks (MANs), and wide area networks (WANs). The basic operation of Ethernet is provided along with how Ethernet has evolved and the different types of Ethernet systems that are available today. Discover how data networks are configured and managed using simple network management protocol (SNMP). Learn the basic operation of gateways and firewalls and how firewalls operate to protect networks from the unwanted transmission of information. The operation of different types of data systems and how they operate is explained including Ethernet, Token Ring, FDDI, PON, ATM, Frame Relay, and the Internet. Find out how data networks can be configured to allow many users to share the same data network using virtual private networks. You will lean about the common types of data services such as CBR, ABR, UBR and their typical service costs. Some of the most important topics featured are: .Functional parts of data networks .Descriptions of hubs, routers, bridges and gateways. .The differences between PAN, PDN, LAN, MAN, and WAN Networks .How Ethernet and other types of data networks operate .How packets are automatically routed in IP networks .How gateways and firewalls operate .Overviews of Ethernet, Token Ring, FDDI, PON, ATM, Frame Relay and the Internet .Introduction to virtual networks (VPNs) .Data services including CBR, ABR and UBR

For undergraduate/graduate/MBA-level courses in Business Data Communications, Introduction to Data Communications, Telecommunications, and Introduction to Networking. Using a unique modular approach, this cutting-edge introduction to data communications features 11 core chapters of essential material, 6 advanced modules, and a Companion Website to provide the widest possible range of topics around which to customize courses with specific goals. This approach allows selective emphasis without requiring instructors to assemble their own additional material. Plus, 9 mini-chapters for hands-on material and case studies give students a feel for what they will encounter on the job.

This book constitutes the refereed proceedings of the 13th International Conference on Passive and Active Measurement, PAM 2012, held in Vienna, Austria, in March 2012. The 25 revised full papers presented were carefully reviewed and selected from 83 submissions. The papers were arranged into eight sessions traffic evolution and analysis, large scale monitoring, evaluation methodology, malicious behavior, new measurement initiatives, reassessing tools and methods, perspectives on internet structure and services, and application protocols.

There are many data communications titles covering design, installation, etc, but almost none that specifically focus on industrial networks, which are an essential part of the day-to-day work of industrial control systems engineers, and the main focus of an increasingly large group of network specialists. The focus of this book makes it uniquely relevant to control engineers and network designers working in this area. The industrial application of networking is explored in terms of design, installation and troubleshooting, building the skills required to identify, prevent and fix common industrial data communications problems - both at the design stage and in the maintenance phase. The focus of this book is 'outside the box'. The emphasis goes beyond typical communications issues and theory to provide the necessary toolkit of knowledge to solve industrial communications problems covering RS-232, RS-485, Modbus, Fieldbus, DeviceNet, Ethernet and TCP/IP. The idea of the book is that in reading it you should be able to walk onto your plant, or facility, and troubleshoot and fix communications problems as quickly as possible. This book is the only title that addresses the nuts-and-bolts issues involved in design, installation and troubleshooting that are the day-to-day concern of engineers and network specialists working in industry. * Provides a unique focus on the industrial application of data networks * Emphasis goes beyond typical communications issues and theory to provide the necessary toolkit of knowledge to solve industrial communications problems * Provides the tools to allow engineers in various plants or facilities to troubleshoot and fix communications problems as quickly as possible
