Description: This book is now in its fifth edition. Each edition has corresponded to a dif
ferent phase in the way computer networks were used. When the first edition ap
peared in 1980, networks were an academic curiosity. When the second edition
appeared in 1988, networks were used by universities and large businesses. When
the third edition appeared in 1996, computer networks, especially the Internet, had
become a daily reality for millions of people. By the fourth edition, in 2003, wire
less networks and mobile computers had become commonplace for accessing the
Web and the Internet. Now, in the fifth edition, networks are about content dis
tribution (especially videos using CDNs and peer-to-peer networks) and mobile
phones are small computers on the Internet.
New in the Fifth Edition
Among the many changes in this book, the most important one is the addition
of Prof. David J. Wetherall as a co-author. David brings a rich background in net
working, having cut his teeth designing metropolitan-area networks more than 20
years ago. He has worked with the Internet and wireless networks ever since and
is a professor at the University of Washington, where he has been teaching and
doing research on computer networks and related topics for the past decade.
Of course, the book also has many changes to keep up with the: ever-changing
world of computer networks. Among these are revised and new material on
Wireless networks (802.12 and 802.16)
The 3G networks used by smart phones
RFID and sensor networks
Content distribution using CDNs
Peer-to-peer networks
Real-time media (from stored, streaming, and live sources)
Internet telephony (voice over IP)
Delay-tolerant networks
