This book describes the TCP/IP protocol suite, but from a different perspective than other
texts on TCP/IP. Instead of just describing the protocols and what they do, we'll use a
popular diagnostic tool to watch the protocols in action. Seeing how the protocols operate in
varying circumstances provides a greater understanding of how they work and why certain
design decisions were made. It also provides a look into the implementation of the protocols,
without having to wade through thousands of lines of source code.
When networking protocols were being developed in the 1960s through the 1980s,
expensive, dedicated hardware was required to see the packets going "across the wire."
Extreme familiarity with the protocols was also required to comprehend the packets
displayed by the hardware. Functionality of the hardware analyzers was limited to that built
in by the hardware designers.
Today this has changed dramatically with the ability of the ubiquitous workstation to
monitor a local area network [Mogul 1990]. Just attach a workstation to your network, run
some publicly available software (described in Appendix A), and watch what goes by on the
wire. While many people consider this a tool to be used for diagnosing network problems, it
is also a powerful tool for understanding how the network protocols operate, which is the
goal of this book.
This book is intended for anyone wishing to understand how the TCP/IP protocols operate:
programmers writing network applications, system administrators responsible for
maintaining computer systems and networks utilizing TCP/IP, and users who deal with
TCP/IP applications on a daily basis. Organization of the Book
