We propose the TelcoFog architecture as a novel, secure, highly distributed, and ultra-dense
fog computing infrastructure, which can be allocated at the extreme edge of a wired/wireless …

Estimating the Quality of Transmission (QoT) of the optical signal from source to destination
nodes is the cornerstone of design engineering and service provisioning in optical transport …

Data center (DC) interconnection allows us to have optical transmissions between DCs
directly connected to optical networks, avoiding the use of a packet-based infrastructure …

At the lowest layer of today's communication networks is an optical line system (OLS), a
physical network of equipment, which carries high-frequency analog light signals over …

There is great interest in the disaggregation of hardware and software components in the
networking community. The reason is that such a strategy enables flexible solutions and …

Based on fundamental software-defined networking principles, disaggregated solutions
have recently been proposed for optical transport networks. The first solution of such type …

Communication systems are used not only by voice or file exchange applications, but also
by other types of applications due to the coexistence of multiple and different verticals. Each …

Optical transmission systems provide high capacity, low latency and jitter, and high reliability
for city-scale networks. Recirculating loop experiments have facilitated the study of signal …

The Covid-19 pandemic showed forcefully the fundamental importance broadband data
communication and the internet has in our society. Optical communications forms the …

Due to the fact that the current variability of services is brought by the current networks and
