We consider the tradeoffs between packet delay guarantees and per-timeslot computation complexity in an packet switch operating under the crossbar constraint. It is well known that scheduling packets every timeslot according to a Maximum Weight Matching (MWM) achieves 100% throughput. This algorithm ensures average packet delay is within O(n) timeslots(More)
Future Internet packet switches and routers will have to overcome intrinsic limitations of current electronic switching fabrics, related to the extremely high amount and density of the information to be internally processed, and the consequent very large number of interconnections, and very high power consumption and dissipation. Motivated by this(More)
The design of fabrics for terabit packet switches and routers needs to consider the limitations imposed by electronic technologies. In particular, attention has to be paid to information density and to power consumption and dissipation, as well as to power supply and footprint requirements. Optical technologies can overcome some of these limitations. We(More)
We outline work performed within the framework of a current EC project. The goal is to construct a language-independent information system for a specific domain (environment/ecology/biodiversity) anchored in a language-independent ontology that is linked to wordnets in seven languages. For each language, information extraction and identification of(More)
The design of switching architectures for today's telecommunication networks needs to consider the limits imposed by electronic technology; in particular, it must take into account power consumption and dissipation, as well as power supply and footprint requirements. Currently, optical technology is exploited mainly for transmission over optical links(More)
Wavelength-Routing (WR) networks are the most common solution for core networks. With the access segment moving from copper to Passive Optical Networks (PON), core networks will become one of the major culprits of Internet power consumption. However, WR networks offer some design flexibility which can be exploited to mitigate their energy requirements. One(More)
The revolution in information technology is making open sources more accessible, ubiquitous, and valuable. The international Intelligence Communities have seen open sources grow increasingly easier and cheaper to acquire in recent years. Up to 80% of electronic data is textual and most valuable information is often encoded in pages which are neither(More)
The Web is a huge virtual space where to express and share individual opinions, influencing any aspect of life, with implications for marketing and communication alike. Social Media are influencing consumersâ preferences by shaping their attitudes and behaviors. Monitoring the Social Media activities is a good way to measure customersâ(More)
