The design of fabrics for Terabit packet switches and routers needs to consider the limitations imposed by electronic technology; in particular, more attention has be paid information density power consumption dissipation, as well supply footprint requirements. These issues make difficult package a switch one single rack equipment; thus, optical links start being used interconnect line cards with switching fabric. In this paper, we interconnection architectures that exploit wavelength...
The design of fabrics for terabit packet switches and routers needs to consider the limitations imposed by electronic technologies. In particular, attention has be paid information density power consumption dissipation, as well supply footprint requirements. Optical technologies can overcome some these limitations. We analyze use optical interconnect line cards in routers. For this purpose, single-plane multiplane interconnection architectures are proposed that exploit wavelength agility at...
Optical microring resonators can be integrated on a chip to perform switching operations directly in the optical domain. Thus they become building block create elements on-chip interconnection networks, which promise overcome some of limitations current electronic networks. However, peculiar asymmetric power losses impose new constraints design and control In this work, we study multistage networks optimized for particular metric that name degradation index, characterizes behavior...
The power consumption of large IP routers is incresing too fast with the increase Internet traffic. This can be reduced if Optical Switching Fabrics (OSFs) are used instead electronic backplanes and interconnects. And Arrayed Waveguide Gratings (AWGs) exhibit interesting properties for design implementation OSFs. paper studies how OSFs based upon AWGs scale in terms aggregate switching capacity consumption.
We discuss the power-aware Logical Topology Design problem in wavelength routing networks, and analyze economical impacts of power-efficiency. Results show that energy-optimized logical topologies can bring significant savings.
This paper considers the use of optical fabrics to interconnect linecards in Terabit packet switches and routers, order overcome some limitations current electronic realizations. In a previous [1] we considered WDM passive interconnection architectures that exploited broadcast-and-select approach wavelength agility at implement required switching functionality. A non-trivial modeling used components, based upon characteristics commercially available devices, showed aggregate capacities few...
This paper introduces a prototype that implements an Intelligent Transport Systems (ITS) safety application aiming at enhancing the of Vulnerable Road Users, in specific crossing pedestrians. The solution leverages Internet Things and Vehicle-to-everything (V2X) paradigms: Side Unit exploits information provided by connected camera traffic lights for identifying pedestrians red light it informs incoming vehicles about danger using V2X communication. goal is to distribute intelligence closer...
Optical switching fabrics (OSF) are gaining interest because they promise to satisfy the higher information densities demanded by each successive generation of high-end routers and switches. Silicon microring resonators (MRR) can be employed perform operations directly in optical domain. However, similarly other devices used build all-optical fabrics, such as Arrayed Waveguide Gratings (AWG), MRR-based might show a limited scalability terms port count due crosstalk accumulation caused...
Optical switching fabrics are gaining interest as in multi Terabit devices; the advantages over their electronic equivalents mainly information density and power consumption. Arrayed Waveguide Gratings (AWGs) promising optical devices proposed by academic industrial community to build fabrics. Because of wavelength routing property, AWGs allow reuse different ports introducing in-band crosstalk which strongly limits scalability AWG-based backplanes. However, this effect can be mitigated or...
Nowadays, services in the framework of Cooperative Intelligent Transport Systems (C-ITS) are evolving to tackle more complex scenarios. The State-of-Art C-ITS messages focus on sharing information about specific events, hazards or position and dynamic status connected vehicles. New currently being developed enable road actors share detailed gathered from local sensors. aim is create a Collective Perception that provides better knowledge surrounding environment at vehicle-side. In this paper,...
