Readers' feedback is a natural continuation of this process. Each book is crafted with care and precision, undergoing rigorous development that involves the unique expertise of members from the professional technical community. (I'll install some software for you soon.) I would like to thank God for giving me the opportunity, time, and talent to embark on these bold ventures.Feedback Information At Cisco Press, our goal is to create in-depth technical books of the highest quality and value.

Cisco has built a very successful business selling the equipment that forms the network infrastructure—by some accounts, Cisco has more than 85 percent of the market—and at the same time has seen its Cisco IOS Software become a de facto industry standard. There's no question that internetworking has become a popular field with the enormous growth of the Internet and the increasing convergence of voice, video, and data. Finally, we want to thank Brett Bartow, Chris Cleveland, as well as the other people at Cisco Press for keeping us on track and for getting the book published.Introduction Venture into any bookstore today and you can find numerous books on internetworking covering a wide range of topics from protocols to network design techniques. Thanks also to Bob Olsen, Eric Osborne, Siva Valliappan, Ruchi Kapoor, and Lance McCallum for valuable feedback.

Some of this information has been made public previously through forums, Cisco presentations, and the Cisco Technical Assistance Center. This book is an attempt to bring together, in one place, the wealth of information about the architecture and the operation of IOS. In addition, we collectively have answered countless numbers of questions (and dispelled some myths) from bewildered Cisco customers about the workings of various IOS features. During our experience helping design and troubleshoot IOS-based networks, we've seen many cases where limited IOS architectural knowledge either contributed to a problem or made it more difficult to solve. This lack of information is understandable—IOS is proprietary, after all—but it nevertheless leaves network implementers at a disadvantage.

You might notice that this book does not cover many of the Cisco platforms in particular, this book does not cover any of the Catalyst switch products, and it omits many of the access routers. The hardware descriptions are provided only to help illustrate unique features in the IOS software. Note, however, that this book is not meant to be an exhaustive manual for Cisco hardware. Because IOS is a specialized embedded operating system tightly coupled to the underlying hardware, it's difficult to describe the software without also considering the hardware architecture. This book also covers the architecture of some of Cisco's hardware platforms. The objective of this book is to describe key parts of the architecture and the operation of the IOS software.

Finally, Chapter 8 describes how IOS implements select Quality of Service (QoS) mechanisms. The second section, beginning with Chapter 3, examines the IOS implementations on a few selected Cisco hardware platforms, covering the design and operation of the platform-specific features. The first covers the general architecture of IOS, including its software infrastructure and packet switching architecture.
