What would google do ? is the intriguing title of the new book written by Jeff Jarvis

Napster was probably one of the first popular peer-to-peer application. Since then, many other peer-to-peer techniques and been developed and measurement studies show that in some parts of the Internet peer-to-peer applications generate more packets than classical client server applications. During the last ten years, many papers have been written on peer-to-peer technologies. The new book written by Buford, Yu and Lua has collected more than 550 references and provides a detailed and up-to-date survey on the peer-to-peer world.

This new edition of Douglas Comer's book clearly indicate that networking courses are more and more taught at undergraduate level. The fifth edition of this book is an introductory book on computer networking and TCP/IP in particular. Douglas Comer choose to cover a large number of topics at an introductory level. The book uses a mixed approach. It first starts by describing internet trends and internet applications. Then, it spends 130 pages on the physical layer. This part does not require any specific electrical knowledge.

Fifteen years ago, Richard Stevens wrote the first volume of TCP/IP Illustrated. In his book, he took a different approach than the existing books. Instead of describing TCP/IP from a theoretical viewpoint, he took an "exploratory" approach. He set up a small network and looked at the packets exchanged to explain in details the core IPv4 and TCP protocols. Today, the TCP/IP protocol suite has changed significantly with the introduction of IPv6, new applications and changes to many of the Internet protocols.

The architecture of today's Internet was mainly designed together with the TCP and IP protocols in the 1970s and early 1980s. During the last years, researchers and funding organisations in America, Europa, Asia have started to work on different alternative architectures for the Internet. Some consider an evolutionnary approach where the Internet architecture would be incrementally modified in a backward compatible manner while other consider that a completely new architecture should be developped to take into account the requirements of today's and tomorrow's Internet.
