I want to set the expectations straight. This is not the best Winsock programming book. This book address higher level issues with network programming and it does a very good job at it. It is going to presents the different options for writing a server such as concurrent vs iterative or single thread vs multithread and explains carefully the tradeoff of each option. In my opinion that is the strength and the originality of the book. Another favorite part of the book is the presentation of the complete implementation of a telnet client where the author leads you through all the design and implementation process by explaining you the reasoning behind each decision.

What I did not like about the book is that like the volume 1, too many topics are covered so in many chapters the author barely touch the topic without going in depth into it and I am questioning the value of these chapters as reference.

This is the Windows version but there is also a Linux/Posix Sockets and a BSD sockets versions.
