Location: Aula de Grados, 5.1.A01, Edificio Padre Soler, Universidad Carlos III de Madrid, Campus de Leganés Dates: 15 Octubre, 2008, 9:00 – 19:00 Organization: Cátedra Telefónica de la Universidad Politécnica de Madrid (UPM) The symposia will be conducted in Spanish

A systems approach to network coding and random coding: Explain how network coding is used in wireless networks Show an example of random coding to implement network coding This talk on network and random coding is of particular interest to researchers tackling wireless, P2P and multipath routing.

Meeting: IMDEA Networks Board of Trustees

Meeting: IMDEA Networks Scientific Council The meeting will be conducted in English

The madri+d Forum on Communications Technologies is hosted by University Carlos III of Madrid (UC3M) on its Leganes Campus. The conference, "The Role of Europe in Internet Governance", will begin with a presentation on the international research institute, IMDEA Networks, by its Director, Dr. Arturo Azcorra, and will be followed by a speech by Professor Jon Crowcroft, Marconi Professor in Networked Systems at the University of Cambridge.

In work at Washington St Louis and Stanford on network virtualization a lot of the research is predicated on lots of fancy hardware for forwarding (viz NetFPGA) (a recent SIGCOMM reject by UCL/Lancaster people on this got multiple GigEs at line rate fairly nicely – a good solid piece of work on mid-range affordable virtualized routers) – but that is virtualized _forwarding_ – the real control plane is the routing protocols- if you want to virtualize that, its because you want multiple co-existing routing computations (possibly for isolated VPNs, or possible for services for different users or for robustness to attack etc etc etc) so then what you want is META routing.

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. Two emerging areas of research will be the focus of attention: the e-medicine and the e-participation.

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 this course is to learn how to model cellular systems for the use in optimizing the design of this type of network. The course will consist of the following parts: A revision of basic queueing models Analysis of cellular systems with a single cell Channel reservation strategies possibility for the design of systems that optimize performance whilst minimizing the probability of interrupting current sessions Models and algorithms to support the different priorities of existing users Flow guarantees to different users through models of service differentiation Hierarchical cellular structures

This course is focused on the optimization problems that arise in network communications design and planning. First the mathematical techniques involved in constrained optimization are introduced. Then, a taxonomy of network planning problems is reviewed. Representative examples are provided and modeled as constrained optimization problems. After that, algorithm and problem complexity classification is introduced, next to an evaluation of complexity issues in constrained optimization problems. Finally, a section introducing graph theory as a feasible approach for network optimization is included.
