A GRASP with path-relinking heuristic for the survivable IP/MPLS-over-WSON multi-layer network optimization problem
Pedrola Escribà, Òscar; Ruiz Ramírez, Marc; Velasco Esteban, Luis Domingo; Careglio, Davide; González de Dios, Óscar; Comellas Colomé, Jaume (2013-12)
Article
Accés restringit per política de l'editorialIn this paper we deal with the survivable internet protocol (IP)/multi-protocol label switching (MPLS)-over-wavelength switched optical network (WSON) multi-layer network optimization problem (SIMNO). This problem entails ... -
Bridging the Interoperability Gap Between the Internet and Optical Network Management Systems
Yannuzzi, Marcelo; Masip Bruin, Xavier; González de Dios, Óscar; García Argos, Carlos; Maciejewski, Maciej; Altmann, Jorn (IEEE Computer Society Publications, 2011)
Text en actes de congrés
Accés restringit per política de l'editorialDespite the efforts made towards the convergence of packet and circuit switched technologies, the isolation between the Internet and the optical Network Management Systems (NMSs) remains unsolved. Today, carriers have ... -
Coordinated Computation of Multi-layer Paths via Inter-layer PCE Communication: Standards, Interoperability and Deployment
Chamania, Mohit; González de Dios, Óscar; López, Víctor; Cuaresma, Marta; Drogon, Marek; Jukan, Admela; Masip Bruin, Xavier; Yannuzzi, Marcelo (2012)
Text en actes de congrés
Accés obertThe Path Computation Element (PCE) is positioned nowadays as one of the solutions that almost every carrier will eventually deploy. The PCE architecture as well as a number of components, including the PCE Communication ... -
Finding an objective cost for sliceable flexgrid transponders
Velasco Esteban, Luis Domingo; González de Dios, Óscar; López, Víctor; Fernández Palacios, Juan Pedro; Junyent Giralt, Gabriel (The Optical Society (OSA), 2014)
Text en actes de congrés
Accés obertWe analyze the objective cost of SBVTs as a function of the traffic conveyed by IP/MPLS-over-flexgrid networks. Optimal results show that cost increment with respect to BVTs is related to the aggregation level. -
Modeling physical-layer impairments in multi-domain optical networks
Yannuzzi, Marcelo; Marín Tordera, Eva; Serral Gracià, René; Masip Bruin, Xavier; González de Dios, Óscar; Jimenez Chico, Javier; Verchere, Dominique (IEEE Computer Society Publications, 2011)
Text en actes de congrés
Accés restringit per política de l'editorialThe advantages of optical transparency are still confined to the boundaries of a domain, since the optical signals are subject to O/E/O conversions at the border nodes that separate two optical domains. The extension ... -
