Monolithic IP-routers architectures are becoming inadequate with respect to the increase in traffic volume and network function complexity coming from new services. Current technological constraints prevent this kind of design and constructive approach to go further, while decentralized and modular systems seem to offer a better solution to the quest for the next generation router architecture. In...
The concept of "green" and energy-efficient networking has begun to spread over the past few years, gaining an increasing popularity and interest from service and network providers, as well as equipment manufacturers. In this contribution, we propose an analytical framework that can effectively be adopted to optimize power consumption of a network device with respect to its expected forwarding...
We consider a new generation of COTS software routers (SRs), able to effectively exploit multi-core/CPU HW platforms. Our main objective is to analyze, to evaluate and to model the impact of power saving mechanisms, generally included in today's COTS processors, on the SR behavior and networking performance. To this purpose, we tried to understand and to separately characterize the roles of both HW...
Results from the gas gain monitoring (GGM) system for the muon detector using RPC in the CMS experiment at the LHC is presented. The system is designed to provide fast and accurate determination of any shift in the working point of the chambers due to gas mixture changes.
We investigate how X-ray exposure impact the long term reliability of 130-nm NMOSFETs as a function of device geometry and irradiation bias conditions. This work focuses on electrical stresses on n-channel MOSFETs previously irradiated with X-ray up to 136 Mrad(SiO2) in different bias conditions. Irradiation is shown to negatively affect the degradation during subsequent hot carrier injection. Increasing...
MARSIS (Mars advanced Radar for subsurface and ionosphere sounding) is a low frequency nadir looking sounding radar selected by ESA as a payload of the Mars Express mission, whose primary Scientific Objective is to map the distribution of water both solid and liquid, at global scale on the Martin crust. MARSIS is the first instrument to be able to detect what lies beneath the surface of Mars (up to...
