This is an invaluable text for anyone wishing to implement TCP/IP in an embedded system and would also be ideal as an undergraduate text for the practical aspects of Computer Networks & Communications. The first chapter gives a brief overview of networking hardware and software, SLIP over RS232 and Ethernet protocols, device drivers and timing as well as state machines and buffering considerations. The second chapter discusses the OSI model & demonstrates the fundamentals of a networking protocol with sample program fragments written in the 'C' programming language. Chapters 3 through 7 give detailed coverage of the core networking protocols including ARP, IP and ICMP, UDP, TCP, Telnet and finally HTTP. These protocols are exercised, tested and explained with 'C' sample code and explanations of test results. The sample code effectively forms a library of low level networking source code written in 'C'. Chapters 8 through 11 demonstrate various working applications based on a PIC microcontroller - a real embedded system. The really nice thing about this book is the source code and utilities provided on the CD for virtually all 'C' compilers including Microsoft VisualC++ 6.0, Borland and the FREE GNU C (+IDE). I have given this text a five star rating and would recommend it to embedded systems programmers needing to implement TCP/IP as well as undergraduate students studying networking.
