Many times I have been asked to explain “ briefl y ” how SDH, SONET, and the OTN “ exactly ” work. The questions came mainly from new colleagues, stu- dents, and users of these technologies, personally or via the usenet newsgroup comp.dcom.sdh - sonet. I could have referred them to the standards documents, but to provide a more consistent and clear answer I decided to write this pocket guide. The objective of this book is that it can be used both as an introduction as well as a reference guide to these technologies and their spe- cifi c standards documents.

When the authors of this book asked me to write the foreword of their work on the digital enterprise, I immediately thought that it was one more document on a fashionable topic in the technology and the business world of the 21st Century often addressed by consulting firms, some of which have aspired to become experts on the subject. However, a more careful observation reveals that an issue more important than the sole subject of the digital enterprise is: “Is your company fully operational?”, because this is the real topic.

The fi rst edition of this book came about because Regina Lundgren had always been fascinated with communication. She started writing novels in the third grade. When she was asked on her fi rst day at the University of Washington what she hoped to do with her degree in scientifi c and technical communication, she replied, “I want to write environ- mental impact statements.” When Patricia Clark hired her to work at the Pacifi c Northwest National Laboratory to do just that, she was overjoyed.

The idea for this book was born during one of my project-related trips to the beautiful city of Hangzhou in China, where in the role of Chief Architect I had to guide a team of very young, very smart and extremely dedicated software developers and verification engineers. Soon it became clear that as eager as the team was to jump into the coding, it did not have any experience in system architecture and design and if I did not want to spend all my time in constant travel between San Francisco and Hangzhou, the only option was to groom a number of local junior architects. Logically, one of the first questions being asked by these carefully selected future architects was whether I could recommend a book or other learning material that could speed up the learning cycle. I could not. Of course, there were many books on various related topics, but many of them were too old and most of the updated information was either somewhere on the Internet dispersed between many sites and online magazines, or buried in my brain along with many years of experience of system architecture.

I would like to thank you for purchasing the second edition of “Industrial Network Security,” especially if you are one of the many supporters of the first edition. When the second edition was announced, many people asked me, “why a second edition?” and even more followed that up with, “and why a coauthor?” These ques- tions are harder to answer than you would think.

RFID Applied is just that. It’s about the application of RFID. If you want a book about electrical and computer engineering you need another source. Let’s say that you have been asked to lead an effort at your company to use RFID in your supply chain. You have heard about RFID because so much has been written on the topic since Wal-Mart and the US DoD made their proclamations that shippers attach RFID tags to their deliveries. This book is for you!
