Professors spend lots of time to prepare their courses. They often develop slides that are used to taught one course per year. During the last ten years, I have revised the slides that I use several times to improve the presentation or add/remove some topics. The slides are now stable and contain lots of animation to help students to better understand some of the networking topics.

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.

A few years ago, Juniper Networks used cartoons and humour to attack its rival cisco in a marketing campaign with companion postcards and lots of cartoons. Recently, Juniper decided to come back to traditional marketing and removed the cartoons from its website. Cisco took the opposite direction with a new marketing campaign based on flash videos : http://www.cisco.com/cdc_content_elements/flash/security/therealm/index....

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.

In Europe, a large fraction of the Internet traffic is exchanged at interconnection points such as LINX in London, BNIX in Belgium, SFINX, in Paris. AMS-IX, based in Amsterdam is one of the oldest and the largest interconnection points in Europe.
