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 Internet 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 examined the mobility and security with the intention of understanding the current architecture and what might be done for a next generation architecture.

La Feria Madrid por la Ciencia (The Forum for Science) is a key part of the Programa de Ciencia y Sociedad (Science and Society Program) that the Regional Government of Madrid launched in 2000, through the Dirección General de Universidades e Investigación (Directorate-General of Universities and Research). This Program seeks not only to promote dialogue between citizens and scientists, but also to increase the public’s participation in science.

The objective of these symposia is to celebrate idea-sharing sessions on the importance of the technological medium of telematic networks in general, and of the REDIMadrid network in particular, for the development of leading research activity at World level. The collaborative support on the activity of distributed research groups, GRID environments, distributed super-computers and scientific databases are examples of its application to almost any field of scientific research.
