Institute IMDEA Networks Open House 2011: Research and development

Why should I consider a future in research? What sort of opportunities does a PhD open up for me? What makes research in the science of networks such an exciting career choice? How can we ensure that the Internet can grow and adapt to ever-changing needs over the coming decades? What lies beyond the Internet? What inspires network research?

Online Testing of Deployed Federated and Heterogeneous Distributed Systems

Dejan Kostic, Tenure Track Assistant Professor at the Networked Systems Laboratory, EPFL
It is notoriously difficult to make distributed systems reliable. This becomes even harder in the case of the widely-deployed systems that are heterogeneous (multiple implementations) and federated (multiple administrative entities). The set of routers in charge of the Internet's inter-domain routing is a prime example of such a system.

Bounds on QoS-Constrained Energy Savings in Cellular Access Networks with Sleep Modes

Balaji Rengarajan, Institute IMDEA Networks; Gianluca Rizzo, Institute IMDEA Networks; Marco Ajmone Marsan, Institute IMDEA Networks & Politecnico di Torino
Sleep modes are emerging as a promising technique for energy-efficient networking: by adequately putting to sleep and waking up network resources according to traffic demands, a proportionality between energy consumption and network utilization can be approached, with important reductions in energy consumption. Previous studies have investigated and evaluated sleep modes for wireless access networks, computing variable percentages of energy savings.

FLAVIA: Project Plenary Meeting

Aula 4. 1F03, Departamento de Telemática, Edificio Torres Quevedo, Universidad Carlos III de Madrid, Avda. Universidad, 30, 28911 Leganes – Madrid
La importancia de las redes inalámbricas para la Futura Internet crece a un ritmo acelerado a medida que los dispositivos móviles se convierten cada vez más en su punto de acceso. No obstante, y como consecuencia de su diseño arquitectónico rígido, las redes inalámbricas actuales no son capaces de adaptarse rápidamente a contextos y necesidades de servicio evolutivos. Creemos que la capacidad de Internet para mantenerse al día con la innovación procede directamente de su dependencia de la abstracción tradicional de una Internet basada en capas.

Unrevealing the structure of live BitTorrent Swarms: methodology and analysis

Michal Kryczka, Institute IMDEA Networks; Rubén Cuevas, Universidad Carlos III de Madrid; Carmen Guerrero, Universidad Carlos III de Madrid; Arturo Azcorra, Universidad Carlos III de Madrid
BitTorrent is one of the most popular application in the current Internet. However, we still have little knowledge about the topology of real BitTorrent swarms and how the traffic is actually exchanged among peers. This paper addresses fundamental questions regarding the topology of live BitTorrent swarms. For this purpose we have collected the evolution of the graph topology of 250 real torrents from its birth during a period of 15 days. Using this dataset we first demonstrate that real BitTorrent swarms are neither random graphs nor small world networks.

Algorithmic Mechanisms for Internet Supercomputing under Unreliable Communication

Evgenia Christoforou, University of Cyprus; Antonio Fernández Anta, Institute IMDEA Networks; Chryssis Georgiou, University of Cyprus; Miguel A. Mosteiro, Rutgers University at Universidad Rey Juan Carlos
This work, using a game-theoretic approach, considers Internet-based computations, where a master processor assigns, over the Internet, a computational task to a set of untrusted worker processors, and collects their responses. The master must obtain the correct task result, while maximizing its benefit. Building on prior work, we consider a framework where altruistic, malicious, and rational workers co-exist. In addition, we consider the possibility that the communication between the master and the workers is not reliable, and that workers could be unavailable; assumptions that are very realistic for Internet-based master-worker computations.
