QoS-Enabled distributed access on optical burst-switched networks
(IEEE Press. Institute of Electrical and Electronics Engineers, 2010-01)
Comunicació de congrés
Accés obertOptical Burst Switching (OBS) has been proposed as an efficient technology to cope with the ever increasing bursty traffic on the Internet. The emergence of a broad range of network-driven applications (e.g. multimedia, ... -
Real burst traffic amplification in optically gain clamped amplifier
(2008-02-24)
Comunicació de congrés
Accés obertOptical burst amplification in a gain-stabilized amplifier is theoretically investigated using real burst traffic data. The results show that excellent performance are obtained for WDM transmission with negligible interplay ... -
Regenerator allocation in translucent networks under inaccurate physical information
(2009-12-14)
Text en actes de congrés
Accés obertOptimized regenerator allocation techniques select which of the already installed regenerators in a translucent network must be used in order to maximize the quality of the optical signal while minimizing the opaqueness ... -
Regenerator allocation in WDM networks with uncertainities in the Q factor
(2010-06-14)
Text en actes de congrés
Accés obertThe performance of the regenerator allocation algorithms in WDM networks strongly depends on the accuracy of the physical-layer information such as the Q factor. In a translucent WDM network the already installed ... -

Spectrum defragmentation in elastic optical networks
(Universitat Politècnica de Catalunya, 2016-06)
Treball Final de Grau
Accés obertIn the present project we have studied the concept and several techniques for spectrum defragmentation in elastic optical networks. The simulation tool used was the software named MATLAB, in which all the algorithms here ... -
Study of signal integrity in Flex-Grid optical networks
(Universitat Politècnica de Catalunya, 2016-06)
Treball Final de Grau
Accés obertThis project has studied the behaviour of optical signals in a FlexGrid network. More specifically, we have focused on finding the minimum distance that must exist between two signals such that we achieve a given BER, and ... -
Técnicas de etiquetado de señales ópticas en redes de conmutación de ráfagas
(Escola Tècnica Superior d'Enginyers de Telecomunicació de Barcelona, 2003)
Article
Accés obertEn este artículo presentamos una revision de los asuntos mas importantes relacionados con las redes de conmutacion de ráfagas de señales ópticas etiquetadas (LOBS - Labeled optical burst switched) y las tecnologias que ... -
The Minimum Coincidence Routing Approach in Wavelength-Routed Optical WDM Networks
(IEEE Computer Society Publications, 2009)
Text en actes de congrés
Accés obertManagement is a critical issue in optical networks. Highly impacting in management, routing in optical networks, is often decoupled into both the path selection and the wavelength assignment problems. In the former, ... -
Ultra-dense, transparent and resilient ring-tree access network using coupler-based remote nodes and homodyne transceivers
(IEEE Press. Institute of Electrical and Electronics Engineers, 2009)
Text en actes de congrés
Accés obertWe propose an Ultra-Dense Wavelength Division Multiplex Passive Optical Network (UD-WDM-PON) based on homodyne detection in a totally transparent ring-tree implementation. It is based on time switching phase diversity ... -
Virtualización de xPON con SDN
(Universitat Politècnica de Catalunya, 2016-10)
Projecte/Treball Final de Carrera
Accés obertSDN is a novel paradigm that enables more efficient operation and management in networks, by centralizing some functions that are distributed in the current network architectures. SIEPON is a novel standard that adds ... -
