Metaheuristic hybridizations for the regenerator placement and dimensioning problem in sub-wavelength switching optical networks
Pedrola Escribà, Òscar; Careglio, Davide; Klinkowski, Miroslaw; Velasco Esteban, Luis Domingo; Bergman, K.; Solé Pareta, Josep (Elsevier, 2013-02-01)
Article
Accés restringit per política de l'editorialPhysical layer impairments severely limit the reach and capacity of optical systems, thereby hampering the deployment of transparent optical networks (i.e., no electrical signal regenerators are required). Besides, the ... -
Modelling and performance evaluation of a translucent OBS network architecture
Pedrola Escribà, Òscar; Careglio, Davide; Klinkowski, Miroslaw; Solé Pareta, Josep (IEEE Computer Society Publications, 2010)
Text en actes de congrés
Accés obertMost research works in optical burst switching (OBS) networks do not take into account the impact of physical layer impairments (PLIs) either by considering fully transparent (i.e., using optical 3R regeneration) or opaque ... -
Offline routing and regenerator placement and dimensioning for translucent OBS networks
Pedrola Escribà, Òscar; Careglio, Davide; Klinkowski, Miroslaw; Solé Pareta, Josep (IEEE Press. Institute of Electrical and Electronics Engineers, 2011-09)
Article
Accés restringit per política de l'editorialThe deployment of translucent optical networks is considered the most promising short term solution to decrease costs and energy consumption in optical backbone networks. In fact, translucent wavelength switched optical ... -
On the performance of flexgrid-based optical networks
Velasco Esteban, Luis Domingo; Ruiz Ramírez, Marc; Pedrola Escribà, Òscar; Castro Casales, Alberto; Klinkowski, Miroslaw; Careglio, Davide; Comellas Colomé, Jaume (Institute of Electrical and Electronics Engineers (IEEE), 2012)
Text en actes de congrés
Accés restringit per política de l'editorialThe ever increasing IP traffic volume has finally brought to light the high inefficiency of current wavelength-routed rigid-grid networks in matching the client layer requirements. Such an issue results in the deployment ... -
On the physical impairments constraint in OBS networks
Pedrola Escribà, Òscar; Careglio, Davide; Klinkowski, Miroslaw; Solé Pareta, Josep (2010)
Text en actes de congrés
Accés obertThe introduction of sub-wavelength switching is one of the main objectives of the future transparent optical mesh networks. One strong candidate is Optical Burst Switching (OBS) which improves the resource utilisation by ... -
RRPD strategies for a T-OBS network architecture
Pedrola Escribà, Òscar; Careglio, Davide; Klinkowski, Miroslaw; Solé Pareta, Josep (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 ... -
Survivable IP/MPLS-Over-WSON multilayer network optimization
Ruiz Ramírez, Marc; Pedrola Escribà, Òscar; Velasco Esteban, Luis Domingo; Careglio, Davide; Fernández Palacios, Juan Pedro; Junyent Giralt, Gabriel (Optical Society of America, 2011-08-01)
Article
Accés obertNetwork operators are facing the problem of dimensioning their networks for the expected huge IP traffic volumes while keeping constant or even reducing the connectivity prices. Therefore, new architectural solutions able ... -
Translucent OBS network architectures with Dedicated and Shared wavelength resources
Pedrola Escribà, Òscar; Careglio, Davide; Klinkowski, Miroslaw; Solé Pareta, Josep (IEEE, 2011)
Text en actes de congrés
Accés restringit per política de l'editorialThe deployment of translucent optical networks is considered the most promising short term solution to decrease costs and energy consumption in optical backbone networks. Indeed, due to the technological maturity of ...
