"What makes this book unique, in my estimation, is the level of detail and attention to history. It provides background and a sense for the ways in which solutions to networking problems have evolved. It is relentless in its effort to achieve precision and to expose remaining problem areas. For an engineer determined to refine and secure Internet operation or to explore alternative solutions to persistent problems, the insights provided by this book will be invaluable. The authors deserve credit for a thorough rendering of the technology of today’s Internet."

Praise for the First Edition of TCP/IP Illustrated, Volume 1: The Protocols . . .

“This is sure to be the bible for TCP/IP developers and users. Within minutes of picking up the text, I encountered several scenarios that had tripped up both my colleagues and myself in the past. Stevens reveals many of the mysteries once held tightly by the ever-elusive networking gurus. Having been involved in the implementation of TCP/IP for some years now, I consider this by far the finest text to date.”

―Robert A. Ciampa, network engineer, Synernetics, division of 3COM

“While all of Stevens’ books are readable and technically excellent, this new opus is awesome. Although many books describe the TCP/IP protocols, Stevens provides a level of depth and real-world detail lacking from the competition. He puts the reader inside TCP/IP using a visual approach and shows the protocols in action.”

―Steven Baker, networking columnist, Unix Review

“TCP/IP Illustrated, Volume 1, is an excellent reference for developers, network administrators, or anyone who needs to understand TCP/IP technology. TCP/IP Illustrated is comprehensive in its coverage of TCP/IP topics, providing enough details to satisfy the experts while giving enough background and commentary for the novice.”

―Bob Williams, vice president, Marketing, NetManage, Inc.

“. . . [T]he difference is that Stevens wants to show as well as tell about the protocols. His principal teaching tools are straightforward explanations, exercises at the ends of chapters, byte-by-byte diagrams of headers and the like, and listings of actual traffic as examples.”

―Walter Zintz, UnixWorld

“Much better than theory only. . . . W. Richard Stevens takes a multihost-based configuration and uses it as a travelogue of TCP/IP examples with illustrations. TCP/IP Illustrated, Volume 1, is based on practical examples that reinforce the theory―distinguishing this book from others on the subject, and making it both readable and informative.”

―Peter M. Haverlock, consultant, IBM TCP/IP Development

“The diagrams he uses are excellent and his writing style is clear and readable. In sum, Stevens has made a complex topic easy to understand. This book merits everyone’s attention. Please read it and keep it on your bookshelf.”

―Elizabeth Zinkann, sys admin

“W. Richard Stevens has produced a fine text and reference work. It is well organized and very clearly written with, as the title suggests, many excellent illustrations expos

Kevin R. Fall, Ph.D., has worked with TCP/IP for more than twenty-five years, and served on the Internet Architecture Board. He co-chairs the Internet Research Task Force’s Delay Tolerant Networking Research Group (DTNRG), which explores networking in extreme and performance-challenged environments. He is an IEEE Fellow.

W. Richard Stevens, Ph.D. (1951-1999), was the pioneering author who taught a generation of network professionals the TCP/IP skills they’ve used to make the Internet central to everyday life. His best-selling books included all three volumes of TCP/IP Illustrated (Addison-Wesley), as well as UNIX Network Programming (Prentice Hall).
