ECOC 2024; 50th European Conference on Optical Communication
Year: 2024 | Conference Paper |
This paper presents a multi-layer transport SDN controller architecture and resource assignment algorithm to manage dynamic IP full-mesh virtual network topologies over ultra-wideband WDM optical networks that combine wavelength and waveband switching by providing waveband channels between IP routers that are backfilled with wavelength channels.Show More

Photonic and Quantum Communication Technologies for Optical Networks Evolution
Michela Svaluto Moreolo;Laia Nadal;Josep M. Fabrega;Javier Vílchez
2023 23rd International Conference on Transparent Optical Networks (ICTON)
Year: 2023 | Conference Paper |
The role of photonic technologies and optical communications, as well as quantum communications, is particularly relevant to address the societal challenges posed by 6G networks and for a sustainable network evolution. This work focuses on recent advances in programmable multi-dimensional (spectrally and spatially multiplexed) transmission systems and adaptive high-capacity (multi-Tb/s) photonic t...Show More

Programmable VCSEL-based photonic system architecture for future agile Tb/s metro networks
M. Svaluto Moreolo;J. M. Fabrega;L. Nadal;R. Martinez;R. Casellas;J. Vilchez;R. Munoz;R. Vilalta;A. Gatto;P. Parolari;P. Boffi;C. Neumeyr;D. Larrabeiti;G. Otero;J. P. Fernandez-Palacios
To deal with the challenging requirements of metropolitan area networks (MANs), it is essential to design cost-effective systems that can support high capacity and dynamic adaptation, as well as a synergy of programmability and efficient photonic technologies. This becomes crucial for very large MANs that support 5G, where multihop connections will need to be dynamically established at target capa...Show More

Experimental Analysis of 8-QAM Constellations for Adaptive Optical OFDM Systems
Laia Nadal;Josep Maria Fàbrega;Javier Vílchez;Michela Svaluto Moreolo
IEEE Photonics Technology Letters
Cited by: Papers (17)
In this letter, we numerically and experimentally evaluate the influence of adopting different 8-QAM constellations. The performance of flexible/adaptive direct detection optical orthogonal frequency division multiplexing transmission systems has been evaluated in the back-to-back configuration. Metro/regional network scenario is also considered using the four-node photonic mesh network of the ADR...Show More
Integrated IT and network orchestration using OpenStack, OpenDaylight and active stateful PCE for intra and inter data center connectivity
A. Mayoral;R. Vilalta;R. Muñoz;R. Casellas;R. Martínez;J. Vílchez
2014 The European Conference on Optical Communication (ECOC)
Year: 2014 | Conference Paper |
We present an integrated IT and network orchestration using OpenStack for the deployment of virtual machines within DCs and OpenDaylight SDN controller for end-to-end connectivity provisioning across Ethernet networks (Intra-DC) and a GMPLS-enabled WSON with an active stateful PCE (Inter-DC).Show More
