This book goes in depth in how TCP/IP works by showing an actual working TCP/IP stack ANSI C code source. I am a believer that in order to fully understand and effectively use a piece of software, the best way to achieve this goal is to actually study at least once its source code. You will certainly get many insights in how TCP/IP works by reading this book. Unfortunately, for most readers, this will remain a theoretical exercise. I got the opportunity to work with the source code of an embedded TCP/IP stack when I was working at Nortel Networks and actually found a bug with the help of this book. That was at that moment that I truly realized the value of this volume.
