Synopses & Reviews
Best-selling author and leading computer networking authority Douglas Comer builds a comprehensive picture of the technologies that allow the Internet to provide application services such as web browsing and instant messaging. This edition includes new chapters on the use of Internet technology.
The book offers an incomparable tour that explains everything from Internet applications to the lowest levels of packet transmission. It shows how protocols are layered, and explains how a given layer provides services used by the next higher layer. KEY FEATURES
Revised and updated throughout, including:
- FAQ email list with answers to questions from a leading networking authority
- NEWChapter 24, User Datagram Protocol: Introduces an end-to-end datagram protocol and shows how to use it. Once considered insignificant, UDP forms the important basis for multicast and broadcast applications and new applications that transfer audio or video.
- NEWChapter 26, Network Address Translation (NAT): Explains how NAT technology overcomes a major limitation of the Internet by allowing multiple computers to share a single IP address, especially important for residential and small business installations.
- NEWChapter 33, IP Telephony: Discusses the most exciting new Internet application, transmitting telephone calls over the Internet (VoIP). The chapter explains competing standards for IP telephony, including protocols such as H.323, Session Initiation Protocol (SIP), and MegacoIt also shows a sample SIP session.
- Includes a CD-ROM with animations, packet traces, more than 200 photos of networking equipment, code from the book and copies of protocol standards. A Web site with additional items including instructional materials is at http://netbook.cs.purdue.edu
- Accompanying lab manual, Hands-On Networking with Internet Technologies, Second Edition, offers an integrated package for teachers.
Synopsis
Written by a best-selling author and leading computer networking authority, this updated book builds a comprehensive picture of the technologies behind Internet applications. It answers the basic question “how do computer networks and Internets operate?” in the broadest sense and includes an early optional introduction to network programming and applications. The book provides a comprehensive, self-contained tour through all of networking from the lowest levels of data transmission and wiring to the highest levels of application software, explaining how underlying technologies provide services and how Internet applications use those services. At each level, it shows how the facilities and services provided by lower levels are used and extended in the next level. Emphasis on Internet technologies and applications provides readers with substantial sections on Internetworking and Network Applications. For individuals with little or no background in the subject.

About the Author
Dr. Douglas Comer is an internationally recognized expert on TCP/IP protocols, computer networking, and the Internet. One of the researchers who contributed to the Internet as it was being formed in the late 1970s and 1980s, he was a member of the Internet Architecture Board, the group responsible for guiding the Internet's development. He was also chairman of the CSNET technical committee, a member of the CSNET executive committee, and chairman of DARPA's Distributed Systems Architecture Board.
Comer has consulted for industry on the design of computer networks. In addition to giving talks in US universities, each year Comer lectures to academics and networking professionals around the world. Comer's operating system, XINU, and implementation of TCP/IP protocols (both documented in his textbooks), have been used in commercial products.
Comer is a Distinguished Professor of Computer Science at Purdue University. He is currently on leave from Purdue, serving as VP of Research Collaboration at Cisco Systems. Recently, Comer has taught courses on networking, internetworking, computer architecture, and operating systems. He has developed innovative labs that provide students with the opportunity to gain hands-on experience with operating systems, networks, and protocols. In addition to writing a series of best-selling technical books that have been translated into 16 languages, he served as the North American editor of the journal Software — Practice and Experience for 20 years. Comer is a fellow of the ACM. For additional information, visit his web site.
