What is included with this book?

The New copy of this book will include any supplemental materials advertised. Please check the title of the book to determine if it should include any access cards, study guides, lab manuals, CDs, etc.

The Used, Rental and eBook copies of this book are not guaranteed to include any supplemental materials. Typically, only the book itself is included. This is true even if the title states it includes any access cards, study guides, lab manuals, CDs, etc.

This book does not pretend to be a comprehensive record; but it aims at helping to disentangle from an immense mass of material the crucial issues and cardinal decisions. Throughout I have set myself to explain faithfully and to the best of my ability. -- The World Crisis, Winston Churchill BACKGROUNDData network communication and distributed applications rely on underlying communications software that is independent of applications and relieves the application of much of the burden of reliably exchanging data. This communications software is organized into a protocol architecture, the most important incarnation of which is the TCP/IP protocol suite. The TCP/IP protocol suite is now dominant, in terms of products, deployment in data networks, and ongoing computer network research. The most prominent incarnation of this suite is in the Internet and its millions of attached computers. OBJECTIVESThe objective of this book is to provide an up-to-date survey of developments in the areas of computer networks and Internet-based protocols and algorithms. Central problems that confront the network designer are the need to support multimedia and real-time traffic, the need to control congestion, and the need to provide different levels of quality of service (QoS) to different applications.The following basic themes serve to unify the discussion: Principles:Although the scope of this book is broad, there are a number of basic principles that appear repeatedly as themes and that unify this field. Examples are multiplexing, flow control, and error control. The book highlights these principles and contrasts their application in specific areas of technology. Design approaches:The book examines alternative approaches to meeting specific communication requirements. Standards:Standards have come to assume an increasingly important, indeed dominant, role in this field. An understanding of the current status and future direction of technology requires a comprehensive discussion of the related standards. INTENDED AUDIENCEThis book is intended for both a professional and an academic audience. For the professional interested in this field, the book serves as a basic reference volume and is suitable for self study.As a textbook, it is suitable for an advanced undergraduate or graduate course. The book treats a number of advanced topics and provides a brief survey of the required elementary topics. After Part One, the parts are relatively independent. Fewer parts could be covered for a shorter course, and the parts can be covered in any order. PLAN OF THE BOOKThe book is divided into seven parts: Overview Internet Applications Transport Protocols Quality of Service in IP Networks Internet Routing Network and Link Layers Management TopicsIn addition, the book includes an extensive glossary, a list of frequently used acronyms, and a bibliography. Each chapter includes a list of key words, review questions, problems, suggestions for further reading, and pointers to relevant Web sites.The book is intended for both an academic and a professional audience. For the professional interested in this field, the book serves as a basic reference volume and is suitable for self-study. As a textbook, it can be used for a one-semester or two-semester course. It covers the material in the Communication and Networking core course of the joint ACM/IEEE Computing Curricula 2001. The chapters and parts of the book are sufficiently modular to provide a great deal of flexibility in the design of courses. TOP-DOWN AND BOTTOM-UP APPROACHESThe book is laid out to present the material in a top-down fashion. This has the advantage of immediately focusing on the most visible part of the material, the applications, and then seeing, progressiv
