The Basics, the Technologies and Best Practices
Details can be found on the web - when you know what to look for
The aim of this book is to help you understand the technologies behind the devices used in the Internet Of Things. This is done with a mixture of theory, examples and 'war-stories'.
This book may be read by senior students, but it is more » more likely to be read by programmers and developers, who have done some programming of PC's in Windows or Linux, and are now faced with developing devices for the Internet Of Things. Basic programming skills are thus assumed, whereas no prior knowledge on TCP/IP and Digital Signal Processing is needed. Based on many years of experience as developer, university-teacher and manager, the author's personal view on best practices in the embedded world is offered.
* Part I introduces the main features of Embedded Operating Systems and modern highly integrated CPU's and thus builds the foundation for part II.
* Part II - on Internet Protocols and Digital Filters - is the main 'textbook'. It provides a lot of facts, backed up by examples. The many network cases are illustrated with the help of WireShark Captures. The chapter on digital filters is focused on making the reader understand the basics, without getting lost in formulas.
* Part III describes the authors experience with best practices when working with embedded networking. The author's experience as a developer, combined with his overview as manager, results in a pragmatic and highly usable set of guidelines.
One of the strongest features of this book is the many figures. They make the book inviting and helps the reader remember the knowledge given. « less

How TCP/IP Works in a Modern Network
In 1994, W. Richard Stevens and Addison-Wesley published a networking classic: TCP/IP Illustrated. The model for that book was a brilliant, unfettered approach to networking concepts that has proven itself over time to be popular with readers of beginning to intermediate networking knowledge. The Illustrated more » Network takes this time-honored approach and modernizes it by creating not only a much larger and more complicated network, but also by incorporating all the networking advancements that have taken place since the mid-1990s, which are many.
This book takes the popular Stevens approach and modernizes it, employing 2008 equipment, operating systems, and router vendors. It presents an ?illustrated? explanation of how TCP/IP works with consistent examples from a real, working network configuration that includes servers, routers, and workstations. Diagnostic traces allow the reader to follow the discussion with unprecedented clarity and precision. True to the title of the book, there are 330+ diagrams and screen shots, as well as topology diagrams and a unique repeating chapter opening diagram. Illustrations are also used as end-of-chapter questions. A complete and modern network was assembled to write this book, with all the material coming from real objects connected and running on the network, not assumptions. Presents a real world networking scenario the way the reader sees them in a device-agnostic world. Doesn't preach one platform or the other.
Here are ten key differences between the two:
Older operating systems (AIX,svr4,etc.) Newer OSs (XP, Linux, FreeBSD, etc.)
Two routers (Cisco, Telebit (obsolete)) Two routers (M-series, J-series)
Slow Ethernet and SLIP link Fast Ethernet, Gigabit Ethernet, and SONET/SDH links (modern)
Tcpdump for traces Newer, better utility to capture traces (Ethereal, now has
a new name!)

For students writing applications that run over TCP/IP, or for those responsible for managing and maintaining a TCP/IP internet, this book's innovative approach helps readers at all levels to truly understand how TCP/IP really works. Rather than just describing the protocols from an abstract, standards-related more » point of view-describing what the standards say the protocol suite should do-TCP/IP Illustrated, Volume 1 actually shows the protocols in action. Stevens also recognizes that readers deal with multiple TCP/IP implementations on heterogeneous platforms. Therefore, the examples in this book show how current, popular TCP/IP implementations operate-SunOS 4.1.3, Solaris 2.2, System V Release 4, BSD/386, AIX 3.2.2, and 4.4 BSD-and they relate these real-world implementations to the RFC standards. « less
