Certain data-communication protocols hog the spotlight, but all of them have a lot in common. Computer Networking: A Top-Down Approach Featuring the Internet explains the engineering problems that are inherent in communicating digital information from point to point. The top-down approach mentioned in the subtitle means that the book starts at the top of the protocol stack--at the application layer--and works its way down through the other layers, until it reaches bare wire.

The authors, for the most part, shun the well-known seven-layer Open Systems Interconnection (OSI) protocol stack in favor of their own five-layer (application, transport, network, link, and physical) model. It's an effective approach that helps clear away some of the hand waving traditionally associated with the more obtuse layers in the OSI model. The approach is definitely theoretical--don't look here for instructions on configuring Windows 2000 or a Cisco router--but it's relevant to reality, and should help anyone who needs to understand networking as a programmer, system architect, or even administration guru.

The treatment of the network layer, at which routing takes place, is typical of the overall style. In discussing routing, authors James Kurose and Keith Ross explain (by way of lots of clear, definition-packed text) what routing protocols need to do: find the best route to a destination. Then they present the mathematics that determine the best path, show some code that implements those algorithms, and illustrate the logic by using excellent conceptual diagrams. Real-life implementations of the algorithms--including Internet Protocol (both IPv4 and IPv6) and several popular IP routing protocols--help you to make the transition from pure theory to networking technologies. --David Wall

Topics covered: The theory behind data networks, with thorough discussion of the problems that are posed at each level (the application layer gets plenty of attention). For each layer, there's academic coverage of networking problems and solutions, followed by discussion of real technologies. Special sections deal with network security and transmission of digital multimedia.

The third edition adds a chapter on wireless and mobile networks and sections on socket programming with UDP and web servers.Copyright © 2004 Book News, Inc., Portland, OR

Book Description
Computer Networking provides a top-down approach to this study by beginning with applications-level protocols and then working down the protocol stack. Focuses on a specific motivating example of a network-the Internet-as well as introducing students to protocols in a more theoretical context. New short "interlude" on "putting it all together" that follows the coverage of application, transport, network, and datalink layers ties together the various components of the Internet architecture and identifying aspects of the architecture that have made the Internet so successful. A new chapter covers wireless and mobile networking, including in-depth coverage of Wi-Fi, Mobile IP and GSM. Also included is expanded coverage on BGP, wireless security and DNS. This book is designed for readers who need to learn the fundamentals of computer networking. It also has extensive material, on the very latest technology, making it of great interest to networking professionals.

Book Info
Explains the engineering problems that are inherent in communicating digital information from point to point. Introduces the underlying principles of networking while at the same time emphasizing Internet protocols and network applications.

From the Publisher
Networking is much more than dry standards specifying message formats and protocol behaviors. Kurose and Ross focus on teaching the emerging principles of the field and then illustrate these principles with examples drawn from Internet architecture. The discussion is lively, engaging, topical, and up-to-date. This book features a top-down organization with an early emphasis on applications. Studying application-level protocols first allows students to gain an intuitive feel for network protocols. The focus on application-layer paradigms (e.g., client server) and application programming interfaces allows students to get their "hands dirty" early-studying and implementing protocols in the context of applications they use daily. Proceeding though the layered network architecture in a top-down manner, one can first focus on the network services that are needed and then, in turn, study how these services can be provided. This book provides a modern treatment of computer networking. 20 years ago, the HDLC protocol was considered "high-level." Today, there is an emphasis on services, applications and their transport needs, scalability, heterogeneity, performance, security, and manageability. This emphasis, which is driving today's advances, is woven throughout the book. Each copy of this book comes with a prepaid six-month subscription to a companion website. This site includes the full text with an advanced searching feature and a hyper-linked index, Java applets to help demonstrate difficult concepts, links to up-to-date material, and complete supplements for qualified instructors of courses.

FROM THE PUBLISHER

Revised to reflect the rapid changes in the field of networking, Computer Networking provides a top-down approach to this study by beginning with application-level protocols and then working down the protocol stack. An early emphasis is placed on application-layer paradigms and application programming interfaces to allow readers to get their "hands dirty" with protocols and networking concepts in the context of applications they will use in the industry. Networking today is much more (and far more interesting) than standards specifying message formats and protocol behaviors. Professors Kurose and Ross focus on describing emerging principles in a lively and engaging manner and then illustrate these principles with examples drawn from Internet architecture.
