Praise for TCP/IP Illustrated, Volume 1: The Protocols

” Robert A. Ciampa, Network Engineer, Synernetics, division of 3COM

This is sure to be the bible for TCP/IP developers and users. Within minutes of picking up the text, I encountered several scenarios which 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.

” Steven Baker, Networking Columnist, Unix Review

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.

” Bob Williams, V.P. Marketing, NetManage, Inc.

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.

” Walter Zintz, UnixWorld

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

” Peter M. Haverlock, Consultant, IBM TCP/IP Development

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.

” Elizabeth Zinkann, Sys Admin

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 .

” Scott Bradner, Consultant, Harvard University OIT/NSD

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 exposing the intimate details of the logic and operation of IP, TCP, and the supporting cast of protocols and applications.

To Brian Kernighan and John Wait, for their encouragement, faith, and support over the past 5 years.
