Welcome to ARTES webpage

ARTES (Analisis de Redes, Tráfico y Estadística de Servicios) was funded in the earlies 2000’s, leaded by Gonzalo Perera and María Simon for several years. It is a joint research group of the Electric (Instituto de Ingeniería Eléctrica, IIE) and Mathematics Department (Instituto de Matemática y Estadística “Rafael Laguardia”, IMERL), of the Engineering School (FING) of the Universidad de la República (UdelaR), Montevideo, Uruguay. It is committed to the theoretical and applied research on a wide range of issues related to design and management of multi purpose networks (e.g. Internet): performance analysis of a network, network design with Quality of Service (QoS) requirements, network traffic modeling, etc. The group’s main feature is its strong use of stochastic and statistic techniques, an essential tool when studying systems with a high variability, like a big network with many users. In other words, ARTES group is a meeting point for Data Network Engineering and Probability and Statistics.

However, the topics ARTES studies invoke a wide range of tools, both in Engineering and Mathematics fields. Just to give some examples, we could mention mathematical optimization, graphs theory, programming, etc. This is the reason why the group keeps in fluent contact, and shares some projects, with other research groups, both at a national and international level. Some of them are the Operations Research Group of the Informatics Department (INCO) of FING; the Ecole Nationale Supérieure des Télécommunications (ENST) in both their Paris and Brest venues; the Institut National de Recherche en Informatique et en Automatique (INRIA) in its Rennes (France) venue.

Brief Historical Review:

The starting point for this group was the joint seminar organized by the Electrical and Mathematics Department during 1995 and 1996, about “Queing Systems”. This gave birth to the presentation and approval of a CIC project “Mathematical Modelization in Telecommunications” oriented by Prof. María Simón (IIE) and Prof. Gonzalo Perera (IMERL). (note: the CIC funds – Comisión de Investigación Científica- are assigned by FING to research projects which integrate different disciplines)

In 1998, within this project, a seminar on “Large Deviation Theory” was organized. In this seminar the concept of “Effective Bandwidth” was first studied by the group, following Frank Kelly´s notes (see the Material section of the webpage). This gave birth to a first publication (Pechiar, Perera and Simon -2000, published in 2002-, see the Work section in the webpage), after which the group can be considered established. The incorporation of young students and researchers has increased and diversified the topics that the group studies.
