James Kempf de DoCoMo Labs USA, da una charla en UC3M: «Toward a Next Generation Internet Architecture»

Recently, the international networking research community has begun to focus on ideas for a next generation Internet architecture. Before developing a next generation architecture, however, it seems appropriate to understand what exactly the problems are with the current Internt architecture. There seems to be widespread agreement that mobility and security are the primary problems stressing the current Internet, but exactly what the problems with mobility and security are, and in particular, whether the problems are architectural in nature, is under dispute. In this lecture series, we’ll examine the mobility and security with an intention to understand the current architecture and what might be done towards a next generation architecture.

The first day of the series will be devoted to mobility, where the problems look to be architectural in nature and are somewhat clearer. We’ll discuss the architectural problems with mobility and with the solutions to mobility management in the current Internet, then look at the beginnings of a solution in the next generation.

Days two through four will be devoted to security, where the nature of the problem seems somewhat more murkey. In particular, most security systems in the Internet have not been designed based on a particular architecture, but rather as an afterthought when the design for the original system was completed and the designers realized that they needed to add security. We’ll develop an architectural approach to security systems design, and use that approach to analyze a particular wireless Internet security system, namely network access authentication. In addition to the lectures, reading material from the presenter’s upcoming book (currently in progress) on wireless Internet security architectures will be available for those wanting more detail. The schedule will leave lots of time for discussion and comment, so that we can hopefully explore the area with an eye towards teasing out research problems and possible approaches to new solutions.

SHORT BIO

Dr. James Kempf graduated with a Ph.D. in Systems Engineering from the University of Arizona in 1983. Since then, he has been working in industry in Silicon Valley, and has been involved in a variety of product and research projects. In particular, Dr. Kempf worked at Sun Microsystems for 13 years until 2001, where, among other projects, in 1993 he was the software technical lead for a SPARC-based laptop with an early 802.11 prototype. In 1996, Dr. Kempf became active in the IETF, and served on the Internet Architecture Board from 2002-2004. Dr. Kempf has also chaired three IETF working groups that have developed protocols for Internet mobility or security, and has contributed numerous drafts to other IETF working groups in the wireless/mobility area. In 2001, Dr. Kempf joined DoCoMo Labs USA as a Research Fellow. Dr. Kempf’s areas of research interest include security and mobility for the wireless Internet, next generation Internet architectures, and wireless virtual reality and video games.
