A GRASP-based heuristic to design the GMPLS control plane network topology with resilience guarantees
(IEEE Press. Institute of Electrical and Electronics Engineers, 2008)
Text en actes de congrés
Accés restringit per política de l'editorialThe control plane topology has traditionally followed that of the data plane and therefore the design of the former, as well as its resilience, has been addressed in the latter's one. Owing to the fact that a clear separation ... -
Deployment analysis of TDM/WDM single fiber PON with colourless ONU operating at 2.5 Gbps subcarrier multiplexed downstream and 1.25 gbps upstream
(2010)
Text en actes de congrés
Accés obertA single-fiber full-duplex hybrid TDM/WDM-PON is demonstrated to operate at 2.5/1.25 Gbps rates, with RSOA ONU. It achieves high power budget (GPON compliant) at a distances higher than 20km, and serves up to 1280 users. -
Digital phase estimation method based on Karhunen-Loève series expansion for Coherent Phase Diversity Detection
(2010)
Text en actes de congrés
Accés obertA novel phase estimation method for coherent systems is presented and demonstrated. It outperforms 5.5 times the phase noise and spectral width tolerance respect to the other methods. -
Dynamic anycast routing and wavelength assignment in WDM networks using ant colony optimization (ACO)
(IEEE Press. Institute of Electrical and Electronics Engineers, 2011)
Comunicació de congrés
Accés restringit per política de l'editorialAnt colony optimization (ACO) is a probabilistic technique used for solving complex computational problems, such as finding optimal routes in networks. It has been proved to perform better than simulated annealing and ... -
Fortistis: Split extension in dense passive optical networks by inline amplification with remote ASE-shaped pump delivery via colorless optical network units
(2010)
Text en actes de congrés
Accés obertA method for extending the customer density via ASE-pumped splitters in the tree in a WDM/TDM-PON is presented. The influence of Rayleigh backscattering in the feeder is faced, originally prohibiting any upstream transmission. -
GMPLS/PCE/OBST architectures for guaranteed sub-wavelength mesh metro network services
(2011)
Comunicació de congrés
Accés obertThis paper presents three innovative GMPLS/PCE/OBST interworking architectures for mesh metro networks which deliver guaranteed contention-free sub-wavelength services with enhanced channel utilization, yet enabling ... -
On an ONU for full-duplex 10.5 Gbps/lambda with shared delay interferometer for format conversion and chirp filtering
(2011)
Text en actes de congrés
Accés restringit per política de l'editorialChirped IRZ downstream is used together with a delay interferometer and a RSOA at a low complexity ONU for full-duplex 10.5Gbps transmission on a single wavelength, supported by modulation format conversion and optical ... -
RRPD strategies for a T-OBS network architecture
(IEEE, 2011)
Text en actes de congrés
Accés restringit per política de l'editorialIn this paper, we deal with the physical layer impairments (PLIs) in optical burst switching (OBS). In particular we present a formulation of the routing and regenerator placement and dimensioning (RRPD) problem for a ... -
Time Shared Optical Network (TSON): a novel metro architecture for flexible multi-granular services
(2011-11-28)
Article
Accés obertThis paper presents the Time Shared Optical Network (TSON) as metro mesh network architecture for guaranteed, statistically-multiplexed services. TSON proposes a flexible and tunable time-wavelength assignment along with ... -

Comunicació de congrés
Accés obertThis paper presents the TSON metro mesh network architecture for guaranteed, statistically-multiplexed services. It proposes tunable time-wavelength assignment, one-way treebased reservation and node architecture. Results ... -
Wavelength conversion towards Rayleigh backscattering tolerant PONs via four-wave mixing in SOA-based ONUs
(2010)
Text en actes de congrés
Accés obertWavelength shifting in PONs with downstream signal remodulation is presented, allowing upstream transmission over trees with 25km feeder and 1:32 split with penalties <2dB, originally Rayleigh backscattering limited. ...
