— Clustering of nodes in optical networks has been proven an efficient way to serve end to end connectivity. However, clustering requires specific topological characteristics, or alternatively the introduction of significant alterations of an existing topology in order to achieve the expected performance improvements. The comparison of future dynamic(More)
The use of computational tools in the humanities for science 2.0 practices is steadily increasing. This paper examines current research practices of a group of philosophers studying the history of philosophical concepts. We explain the methodology and workflow of these philosophers and provide an overview of tools they currently use in their research. The(More)
The Europeana repository hosts large collections of digitized music manuscripts and prints. This paper investigates how tools and services for this repository can enable Early Music musicologists to carry out their research in a more effective or efficient way, or to carry out research that is impossible to do without such tools or services. We report on(More)
Statistical multiplexing at the optical layer has been considered a critical requirement in order to build the next generation of ultra-high capacity optical transport networks in a cost-efficient manner. However, even today, the state of the art of commercially available optical core networks is based on mature wavelength switching and routing(More)
The agINFRA project ( is a European Commission funded project under the 7th Framework Programme that aimed to introduce agricultural scientific communities to the vision of open and participatory data-intensive science. Working on enhancing the interoperability between heterogeneous data sources, the agINFRA project has left a set of grid-(More)
In this work we benchmark through appropriate performance metrics the legacy Optical Circuit Switching (OCS) mode in an optical network of nodes following a mesh topology interconnection vs. a clustered optical network architecture (CANON). The results demonstrate that the static reservation of WDM channels, as used in IP/WDM schemes, is severely limiting(More)
In this paper we evaluate a hybrid optoelectronic switch architecture, which can be used under optical burst switching (OBS) or even optical packet switching (OPS) schemes. The proposed architecture incorporates electronic switching equipment to a limited degree utilizing the large buffering capacity available only by means of electronic subsystems. This(More)
