Computer Networks: A Systems Approach is a carefully focused revision of the best-selling first edition, updated to incorporate user feedback and reflect the most recent changes in networking technology. Inside, a systems approach focused on the Internet promotes an enduring, practical understanding of networks and their building blocks. Each chapter begins with the statement of a problem that frames the following discussion. The authors then develop complete solutions, illustrate them with real-world examples including specific protocol references and C code and address topical issues debated throughout the networking community. The result? Readers learn the why of network design not just the facts surrounding current systems but the principles at work in their application and evolution. No other textbook offers a more solid grounding or better preparation for a career in networking. Features The authors bring over 20 years of experience in networking research, development and teaching to the task of describing the principles and practical implementation of computer networks. Includes all-new chapters on security techniques and application-layer protocols, and new material on wireless and mobile technology and VPNs. Expands coverage of internet routing, ATM, quality of serivice, and multimedia communication. Highlights key design principles, probes controversial networking issues, provides the definitive references on each topic, and includes over 100 new exercises. Presents implementation examples in easy-to-understand C code. Booknews A systems oriented approach to computer network design, using the Internet as a model for illustrating network protocol design. Chapters on areas such as direct link networks and congestion control offer code fragments from a working protocol environment, the x-kernel, to demonstrate how protocol specifications and design principles are implemented. Includes chapter introductions; summaries; exercises; programming assignments; key paragraphs; and sidebars, plus a highly readable layout. For undergraduate and graduate courses. Annotation c.
