For Business Data Communications, Data Communications, and introductory Networking for Business courses.

The fifth edition of this popular text presents the fundamental concepts of data communications, networking, distributed applications, and network management and security; it relates specifically to the business environment and business management. Includes up-to-date coverage of key issues for the business student—high-speed networks, asychronous transfer mode (ATM) and TCP/IP, and the use of the Internet, intranets, and extranets support business objectives. It is the only book with a top-down Internet first organization.

In this highly successful book by award-winning and best-selling author Williams Stallings, get to know OPNET IT Guru Academic Edition from the inside out by learning hands-on with dozens of real-world scenarios. Discover how easy it is to model IT simulations and compare a host of options - all without running a single wire.

In these modules, you will:
• Build virtual networks, VPNs, and WANs;
• Customize the configuration of each simulation;
• Compare and contrast response times for different architectures;
• Judge the merits and drawbacks of different protocols;
• Analyze Quality of Service and other parameters.
• Evaluate routers, firewalls, hubs and other network devices;
• And much more.

In this new edition of their classic and bestselling textbook, authors Larry Peterson and Bruce Davie continue to emphasize why networks work the way they do. Their "system approach" treats the network as a system composed of interrelated building blocks (as opposed to strict layers), giving students and professionals the best possible conceptual foundation on which to understand current networking technologies, as well as the new ones that will quickly take their place.

Incorporating instructor and user feedback, this edition has also been fully updated and includes all-new material on MPLS and switching, wireless and mobile technology, peer-to-peer networks, Ipv6, overlay and content distribution networks, and more. As in the past, all instruction is rigorously framed by problem statements and supported by specific protocol references, C-code examples, and thought-provoking end-of-chapter exercises.

New to the edition is a downloadable network stimulation lab manual that allows students to visualize and experiment with core networking technologies in direct coordination with the book's discussion. Thanks to this and many other enhancements, Computer Networks: A Systems Approach remains an essential resource for a successful classroom experience and a rewarding career in networking.

This manual has 12 experiments that cover a variety of networking designs and protocols. The experiments in this manual do not require programming skills as a prerequisite. They are generic and can be easily expanded to utilize new technologies and networking standards.

Building on the strength of his two other successful texts, Stallings' new text provides a fresh “Top Down” and comprehensive “Top Down” survey of the entire field of computer networks and Internet technology—including an up-to-date report of leading-edge technologies. It emphasizes both the fundamental principles as well as the critical role of performance in driving protocol and network design. The basic themes of principles, design approaches, and standards throughout the text unify the discussion.

With a focus on the most current technology and a convenient modular format, this best-selling text offers a clear and comprehensive survey of the entire data and computer communications field. Emphasizing both the fundamental principles as well as the critical role of performance in driving protocol and network design, it explores in detail all the critical technical areas in data communications, wide-area networking, local area networking, and protocol design.
