Resource management research in Passive Optical Networks (PON)

Next Generation Access Networks (NGAN) are the new step forward to deliver broadband services and to facilitate the integration of different technologies. It is plausible to assume that, from a technological standpoint, the Future Internet will be composed of long-range high-speed optical networks; a number of wireless networks at the edge; and, in between, several access technologies, among which, the Passive Optical Networks (xPON) are very likely to succeed, due to their simplicity, low-cost, and increased bandwidth. Among the different PON technologies, the Ethernet-PON (EPON) is the most promising alternative to satisfy operator and user needs, due to its cost, flexibility and interoperability with other technologies. One of the most interesting challenges in such technologies relates to the scheduling and allocation of resources in the upstream (shared) channel. The aim of this research project is to study and evaluate current contributions and propose new efficient solutions to address the resource allocation issues in Next Generation EPON (NG-EPON). Key issues in this context are future end-user needs, integrated quality of service (QoS) support and optimized service provisioning for real time and elastic flows. This project will unveil research opportunities, issue recommendations and propose novel mechanisms associated with the convergence within heterogeneous access networks and will thus serve as a basis for long-term research projects in this direction. The project has served as a platform for the generation of new concepts and solutions that were published in national and international conferences, scientific journals and also in book chapter. We expect some more research publications in addition to the ones mentioned to be generated in a few months.

Sistema de apoyo al programa de diversificación curricular en un IES

En este proyecto se incluyen las etapas de análisis previo, análisis de requerimientos y diseño técnico de un sistema de apoyo a la diversificación en un IES, siguiendo los métodos y técnicas descritos en el ciclo de vida en cascada o ciclo de vida clásico del software. Puesto que se llegará hasta la especificación del diseño de la aplicación, esta documentación servirá de base al programador del software para implementar la aplicación, según las indicaciones y necesidades especificadas.

Modelatge i simulació de quatre centres de processament de dades connectats per WAN

Aquest projecte conté l'estudi de la comunicació entre quatre Centres de Processament de Dades (CPD) per via WAN. L'estudi consisteix en simular aquestes comunicacions en un entorn de proves físic i també en entorn de proves virtual on s'han extret resultats dels protocols de seguretat, d'enrutament, a més dels temps de resposta i limitacions dels equips físics i virtuals.
