Since it was first published some 30 years ago, the IP model has emerged as one of the most influential technological developments of our time. As it turns out, its evolution is also one of the more interesting stories in the history of the Internet. At IETF 73, Internet Architecture Board member Dave Thaler gave a well-received presentation called Evolution of the IP Model, which was based on an Internet-Draft published last November. An article based on the presentation, which Dave adapted specifically for the IETF Journal, appears on this page.
Jon Postel was remembered throughout the week, most notably at a private dinner in Minneapolis commemorating the 10-year passing of Jon and honouring this year's winner of the Internet Society's Jonathan B. Postel Service Award. Jon's memory also was deeply felt during the Plenary, particularly when Dave, as part of his presentation, invoked Jon's famous credo: Be con-servative in what you send; be liberal in what you receive.
This edition of the IETF Journal features several other articles of note. Fred Baker offers a new perspective on the transition from IPv4 to IPv6. Kevin Chege of the Kenya Education Network and Mat Ford give us an inside look at the impact of bandwidth-intensive applications on low-bandwidth regions of the global network. Leslie Daigle discusses Internet security and stability in her piece about unwanted traffic on the Internet. And Geoff Huston returns with an in-depth look at the role that resource certification may play in inter-domain routing.
