Abstract:
Abstract This paper presents an attempt to solve the problem of choosing the best combination among the M combinations of shortest paths in optical translucent networks. Fixed routing algorithms demands a single route to each pair of nodes. The existence of multiple shortest paths to some pairs of nodes originates the problem of choose the shortest path which fits better the network requests. The algorithm proposed in this paper is an adaptation of Ant Colony Optimization (ACO) metaheuristic and attempt to define the set of routes that fits in an optimized way the network conditions, resulting in reduced number of blocked requests and better adjusted justice in route distribution. A performance evaluation is conducted in real topologies by simulations, and the proposed algorithm shows better performance between the compared algorithms.

Abstract:
During the last few years, liquid crystalline elastomers (LCEs) have been systematically produced by cross-linking liquid crystalline side-chain polymers. In these networks, a liquid crystalline molecule is fixed at each monomeric unit. LCEs exhibit a novel combination of properties. Due to liquid crystalline groups, they show anisotropic liquid crystalline properties similar to conventional liquid crystals (LCs); but due to the three-dimensional network-structure of the polymer chains, they show typical elastomer properties, such as rubber elasticity or shape stability. One exceptional property of this combination is demonstrated when a mechanical deformation to the LCE causes macroscopically uniform orientation of the long molecular axis of the LC units (the so-called “director”).This response of the LC-phase structure to an applied mechanical field is similar to the effect of electric or magnetic fields on low molecular weight liquid crystals (LMLC), as illustrated in Figure 1. Figure la shows an undeformed LCE. Because of the non-uniform orientation of the director, the sample scatters light strongly so the elastomer is translucent like frosted glass. On the other hand, applying a mechanical field the director becomes uniformly aligned and the sample is transparent (Figure 1b). Such a macroscopically ordered rubber exhibits optical properties very similar to single crystals. These propertie s of LCEs offer new prospects for technical application, e.g., in nonlinear and integrated optics.

Abstract:
AbstractLeydetite, monoclinic Fe(UO2)(SO4)2(H2O)11(IMA 2012–065), is a new supergene uranyl sulfate from Mas d'Alary, Lodève, Hérault, France. It forms yellow to greenish, tabular, transparent to translucent crystals up to 2 mm in size. Crystals have a vitreous lustre. Leydetite has a perfect cleavage on (001). The streak is yellowish white. Mohs hardness is ∼2. The mineral does not fluoresce under long- or short-wavelength UV radiation. Leydetite is colourless in transmitted light, non-pleochroic, biaxial, with α = 1.513(2), γ = 1.522(2) (further optical properties could not be measured). The measured chemical composition of leydetite, FeO 9.28, MgO 0.37, Al2O30.26, CuO 0.14, UO340.19, SO321.91, SiO20.18, H2O 27.67, total 100 wt.%, leads to the empirical formula (based on 21 O a.p.f.u.), (Fe0.93Mg0.07Al0.04Cu0.01)Σ1.05(U1.01O2)(S1.96Si0.02)Σ1.98O8(H2O)11. Leydetite is monoclinic, space group C2/c, with a = 11.3203(3), b = 7.7293(2), c = 21.8145(8) Å, β = 102.402(3)°, V = 1864.18(10) Å3, Z = 4, and Dcalc = 2.55 g cm–3. The six strongest reflections in the X-ray powder diffraction pattern are [dobs in Å (I) (hkl)]: 10.625 (100) (002), 6.277 (1) (11), 5.321 (66) (004), 3.549 (5) (006), 2.663 (4) (008), 2.131 (2) (0 0 10). The crystal structure has been refined from single-crystal X-ray diffraction data to R1 = 0.0224 for 5211 observed reflections with [I > 3σ(I)]. Leydetite possesses a sheet structure based upon the protasite anion topology. The sheet consists of UO7 bipyramids, which share four of their equatorial vertices with SO4 tetrahedra. Each SO4 tetrahedron, in turn, shares two of its vertices with UO7 bipyramids. The remaining unshared equatorial vertex of the bipyramid is occupied by H2O, which extends hydrogen bonds within the sheet to one of a free vertex of the SO4 tetrahedron. Sheets are stacked perpendicular to the c direction. In the interlayer, Fe2+ ions and H2O groups link to the sheets on either side via a network of hydrogen bonds. Leydetite is isostructural with the synthetic compound Mg(UO2)(SO4)2(H2O)11. The name of the new mineral honours Jean Claude Leydet (born 1961), an amateur mineralogist from Brest (France), who discovered the new mineral.

Doutoramento em Engenharia Eletrotécnica
In this thesis a study of optical fiber amplifiers in the context of transparent and dynamic optical networks is performed. We propose and validate a simplified model to estimate the gain profile and amplified spontaneous emission (ASE) noise of broadband counterpumped Raman fiber amplifiers (RFAs). The proposed model requires very low computational resources and it is suitable to be used in network planning tools. Based on the proposed model, we also present an algorithm to design flat gain counter-pumped RFAs for the extended C-band with low computational requirements. We experimentally verify that the pump-reflecting RFA presents a higher transient response due to channels add/drop, when compared to the conventional counter-pumped RFA. This makes this amplifier configuration unsuitable for transparent and dynamic optical networks. To mitigate the transient response due to channel add/drop, a pumpcontrolled gain-locked system based on the monitorization of the reflected pump power is proposed and validated numerically and experimentally. Following this approach, an efficient low-cost RFA suitable for dynamic optical networks is proposed. The dependence of the dynamical response of erbium-doped fiber amplifiers (EDFAs) on the pump wavelength, pump power, and temperature due to spectral hole burning (SHB) and site dependent pumping (SDP) is experimentally investigated. A dependence of the dynamic response on the pump wavelength, for amplifiers pumped around 1480 nm, is shown. In order to explain this dependence, the impact of SDP on the performance of EDFAs pumped at wavelengths around 1480 nm is investigated, both experimentally and numerically. As a result, an improved model incorporating the SDP effect for twolevel EDFAs is derived and experimentally validated.
Nesta tese é feito um estudo sobre amplificadores de fibra ótica no contexto de redes óticas transparentes e dinâmicas. Propomos e validamos um modelo simplificado para estimar o perfil do ganho e do ruído de emissão espontânea amplificada (ASE), para amplificadores de Raman (RFAs) contra propagantes. O modelo proposto requer baixos recursos computacionais e é adequado para ser usado em ferramentas de planeamento da rede. Com base no modelo proposto, apresentamos também um algoritmo com requisitos computacionais baixos para desenhar RFAs contra propagantes com ganho constante para a banda C estendida. Verificamos experimentalmente que um RFA contra propagante com reflexo da potência da bomba devido à adição/remoção de canais apresenta uma resposta transiente mais elevada, quando comparado com um RFA contra propagante convencional. Isto torna esta configuração inadequada para redes óticas transparentes e dinâmicas. Para mitigar a resposta transitória devido à adição/remoção de canais, um sistema de controlo do ganho baseado na monitorização da potência da bomba refletida é proposto e validado numérica e experimentalmente. Seguindo esta abordagem, um RFA contra propagante eficiente e de baixo custo adequado para redes óticas dinâmicas é proposto. A dependência da resposta dinâmica dos amplificadores de fibra dopada com érbio (EDFAs) em função do comprimento de onda da bomba, da potência da bomba e da temperatura devido ao spectral hole burning (SHB) e site dependent pumping (SDP) é investigada experimentalmente. Nos resultados obtidos é mostrada a dependência da resposta dinâmica em função do comprimento de onda da bomba, para amplificadores bombeados em torno de 1480 nm. Para explicar esta dependência, o impacto do SDP no desempenho de EDFAs bombeados em comprimentos de onda em torno de 1480 nm é investigado, tanto experimental como numericamente. Como resultado, um modelo mais completo, incorporando o efeito SDP para EDFAs de dois níveis é derivado e validado experimentalmente.

Abstract:
In order to address the explosive demand for high-capacity and omnipresent wireless access, modern cell-based wireless networks are slowly adopting two major solution roadmaps. The first is the employment of small-cell formations in order to increase the overall spectral efficiency, whereas the second is the employment of higher frequency bands, such as the mm-wave 60GHz band, that offers vast amounts of bandwidth. Depending on the specific application, the above solutions inevitably require the installation and operational management of large amounts of Base Stations (BSs) or Access Points (APs), which ultimately diminishes the overall cost-effectiveness of the architecture. In order to reduce the system cost, Radio over Fiber (RoF) technology has been put forward as an ideal candidate solution, due to the fact that it provides functionally simple antenna units, often termed as Remote Antenna Units (RAUs) that are interconnected to a central managing entity, termed as the Central Office (CO), via an optical fiber. Although extensive research efforts have been dedicated to the development of the physical layer aspects regarding RoF technologies, such as CO/RAU physical layer design and radio signal transport techniques over fiber, very limited efforts have con-centrated on upper layer and resource management issues. In this dissertation, we are concerned with access control and resource management of RoF-based mm-wave network architectures targeting the exploitation of the dual medium and its centralized control properties in order to perform optimal optical/wireless/time resource allocation. In this dissertation, we propose a Medium-Transparent MAC (MT-MAC) protocol that concurrently administers the optical and wireless resources of a 60GHz RoF based network, seamlessly connecting the CO to the wireless terminals through minimal RAU intervention. In this way, the MT-MAC protocol forms extended reach 60GHz WLAN networks offering connectivity amongst wireless devices that are attached to the same or different RAUs under both Line of Sight (LOS) and non LOS conditions. The notion of medium-transparency relies on two parallel contention periods, the first in the optical domain and the second in the wireless frequency and time domains, with nested dataframe structures. The MT-MAC operation is based on a proposed RAU design that allows for wavelength selectivity functions, thus being compatible with completely passive optical distribution network implementations that are predominately used by telecom operators today. Two variants of the MT-MAC protocol are considered. The first offers dynamic wavelength allocation with fixed time windows, whereas the second targets fairness-sensitive applications by offering dynamic wavelength allocation with dynamic transmission opportunity window sizes, based on the number of active clients connected at each RAU. Both variants of the protocol are evaluated by both simulation and analytical means. For the latter part, this thesis introduces two analytical models for calculating saturation throughput and non-saturation packet delay for the converged MT-MAC protocol. Finally, this thesis presents an extensive study regarding the network planning and formation of 60GHz Gigabit WLAN networks when the latter are deployed over existing Passive Optical Network (PON) infrastructures. Three possible architectures where studied: i) the RoF approach, ii) the Radio & Fiber approach and iii) the hybrid RoF-plus-R&F approach that combines the properties of both the aforementioned architectures. During the elaboration of this thesis, one major key conclusion has been extracted. The work proposed in this thesis considers that there is a fundamental requirement for implementing new converged optical/wireless MAC protocols, that have the complete overview of both available resources in order to effectively administer the hybrid Radio-over-Fiber networks.
A fin de atender la demanda explosiva de alta capacidad y acceso inalámbrico omnipresente, las redes inalámbricas basadas en celdas están poco a poco adoptando dos principales guías de solución. La primera es el empleo de formaciones de celdas pequeñas con el fin de aumentar la eficiencia espectral global, mientras que la segunda es el empleo de bandas de frecuencia superior, como la banda de 60GHz, la cual ofrece una gran cantidad de ancho de banda. Dependiendo de la aplicación en específico, las soluciones anteriores inevitable-mente requieren de una instalación y una gestión operativa de grandes cantidades de Estaciones Base o Puntos de Acceso, que en última instancia disminuye la rentabilidad de la arquitectura. Para reducir el coste, la tecnología radioeléctrica por fibra (RoF) se presenta como una solución ideal debido al hecho de que proporciona unidades de antenas de sim-ple funcionamiento, a menudo denominadas Unidades de Antenas Remotas (RAUs), las cuales están interconectadas a una entidad central de gestión, denominada Oficina Central (CO), a través de la fibra óptica. A pesar de que se han dedicado muchos esfuerzos de investigación al desarrollo de varios aspectos de las capas física con respecto a las tecnologías RoF, muy pocos esfuerzos se han concentrado en la capa superior y cuestiones de gestión de recursos. En esta tesis, nos enfocando en el control de acceso y gestión de recursos de arquitecturas RoF y comunicaciones milimétricas, con el fin de aprovechar y explotar el medio dual y las propiedades para realizar una óptima asignación de los recursos ópticos, inalámbricos y temporales. Nosotros proponemos un protocolo Transparente al Medio MAC (MT-MAC) que simultáneamente administre los recursos ópticos e inalámbricos de una red RoF a 60GHz, conectando a la perfección el CO a los terminales inalámbricos a través de una mínima intervención RAU. El protocolo MT-MAC forma unas redes WLAN 60GHz de alcance extendido, ofreciendo así conectividad entre los dispositivos inalámbricos que están conectados al mismo o diferentes RAUs bajo con o sin Línea de Vista (condiciones LOS o NLOS) respectivamente. La noción de transparencia al medio se basa en dos períodos de contención para-lelos, el primero en el dominio óptico y el segundo en la frecuencia inalámbrica y dominio del tiempo, con estructuras de datos anidados. La operación MT-MAC se basa en proponer un diseño RAU que permita la selectividad de funciones de longitud de onda. Dos variantes del protocolo MT- MAC son considerados; el primer ofrece asignación de longitud de onda dinámica con ventanas de tiempo fijo, mientras que la segunda tiene como objetivo entornos de aplicaciones sensibles ofreciendo asignación de longitud de onda con tamaño de ventana de oportunidad de transmisión dinámico, basado en el número de clientes conectados en cada RAU. Ambas variantes del protocolo están evaluadas tanto por medios analíticos como de simulación. En la segunda parte, esta tesis introduce dos modelos analíticos para calcular el rendimiento de saturación y no saturación del retardo de paquetes para el protocolo MT-MAC convergente. Finalmente, esta tesis presenta un extenso estudio de la planificación de red y la formación de redes 60GHz Gigabit WLAN cuando esta se encuentra desplegada sobre las ya existente infraestructuras de Redes Ópticas Pasivas (PONs). Tres posibles arquitecturas han sido estudiadas: i) el enfoque RoF, ii) el enfoque Radio y Fibra , y iii) el enfoque híbrido, RoF más R&F el cual combina las propiedades de ambas arquitecturas anteriormente mencionadas. Durante la elaboración de esta tesis, se ha extraído una importante conclusión: hay un requerimiento fundamental para implementar nuevos protocolos ópticos/inalámbricos convergentes, que tengan una completa visión de ambos recursos disponibles para poder administrar efectivamente las redes de tecnología RoF.

Abstract:

This thesis is about reconfigurable and transparentwavelength division multiplexed (WDM) networks.Reconfigurability is used to achieve higher surveillance andthroughput in the network. This is done by wavelength selectiveand independent network elements. These network elements canaccomplish bypass and protection switching ofthe traffic.Transparency in the optical layer enables the transport networkto accept new bit rates, codes and formats of the clients. Theenabling technologies to achieve a reconfigurable andtransparent network are integrated tuneable devices andswitches. In this thesis some of these devices have beenexperimentally evaluated according to theirs cascadability andcrosstalk performance.

A unidirectional self-healing wavelength divisionmultiplexed ring was designed, assembled and evaluated. Byutilising WDM, logical networks could be constructed withoptical add drop multiplexers (OADM) to support communicativeand distributive services. The main transmission limitation ofthe ring was homogenous broadening of the opticalamplifiers.

The second network element investigated, was the opticalcrossconnect (OXC). The OXC was comprised of optical InP andLiNbO3 switches and tuneable filters, which were experimentallyevaluated. Two OXCs and an OADM were installed in the Stockholmgigabit network (SGN) with fault and configurationmanagement.

The cascadability of OXCs with reshaping repeaters andoptical or electrical switches was investigated. The jitter ofthe OXC with electrical switches limited its performance, whilethe OXC with optical switch was limited by its crosstalk.Crosstalk especially intra-band crosstalk, which beats with thesignal, is a severe limitation of optical networks. Experimentsand simulations were performed on the time dependence of theintra-band crosstalk. It was shown and experimentally confirmedthat the quasi-correlated intra-band crosstalk could be theworst case.

In the next phase of the network five OADMs and one OXC,which interconnected a unidirectional and a bidirectionalprotected ring, were integrated into SGN with a web basedmanagement system.

The OADMs were evaluated in a recirculating loop toinvestigate the cascadability of the nodes. The nodes could bedivided into optical channel or fibre protection and notch ordemultiplex filtering. An optimum of loss of the cascadedoptical amplifiers were found, which maximised the gainflatness and the signal to noise ratio. The OXC utilising fixedWDMs and polymer switches was designed and evaluated takinginto account the configuration, fault handling and performancemonitoring of the optical layer. Data services were evaluatedas clients to the optical layer, especially to provide opticalprotection without interfering with its client.

Optical networks are under constant evolution. The growing demand for dynamism require devices that can accommodate different types of traffic. Thus the study of transparent optical networks arises. This approach makes optical networks more "elegant" , due to a more efficient use of network resources. In this thesis, the author proposes devices that intend to form alternative approaches both in the state of art of these same technologies both in the fitting of this technologies in transparent optical networks. Given that full transparency is difficult to achieve with current technology (perhaps with more developed optical computing this is possible), the author proposes techniques with different levels of transparency. On the topic of performance of optical networks, the author proposes two techniques for monitoring chromatic dispersion with different levels of transparency. In Chapter 3 the proposed technique seems to make more sense for long-haul optical transmission links and high transmission rates, not only due to its moderate complexity but also to its potential moderate/high cost. However it is proposed to several modulation formats, particularly those that have a protruding clock component. In Chapter 4 the transparency level was not tested for various modulation formats, however some transparency is achieved by not adding any electrical device after the receiver (other than an analog-digital converter). This allows that this technique can operate at high transmission rates in excess of 100 Gbit / s, if electro-optical asynchronous sampling is used before the optical receiver. Thus a low cost and low bandwidth photo-detector can be used. In chapter 5 is demonstrated a technique for simultaneously monitoring multiple impairments of the optical network by generating novel performance analysis diagrams and by use of artificial neural networks. In chapter 6 the author demonstrates an all-optical technique for controlling the optical state of polarization and an example of how all-optical signal processing can fully cooperate with optical performance monitoring.

Dessa forma surge o estudo sobre redes ópticas transparentes. Este tipo de abordagem torna as redes ópticas mais ’elegantes’, devido a um uso mais eficiente dos recursos da rede. Nesta tese o autor propõe dispositivos que pretendem formar alternativas quer no estado da arte destas mesmas tecnologias quer no encaixe das mesmas em redes ópticas transparentes. Dado que a transparência total é dificil de alcançar com as tecnologias atuais (talvez com computação óptica mais desenvolvida isso seja possível), o autor propõe técnicas com diferentes níveis de transparência. No âmbito da monitoria de desempenho óptico o autor propôe duas técnicas para a monitoria da dispersão cromática com diferentes niveis de transparência. No Capítulo 3 a técnica proposta parece fazer mais sentido para transmissões ópticas de longo curso e a elevadas taxas de transmissão, não só devido à sua moderada complexidade, mas também ao seu potencial custo. No entanto esta, é proposta para vários formatos de modulação, especialmente aqueles que têm uma componente de relógio bem saliente. No Capítulo 4, o nível de transparência não foi testado para vários formatos de modulação, no entanto alguma transparência é obtida através da não inclusão de nenhum dispositivo eléctrico após o receptor (excepto um conversor analógico-digital). Isto permite que esta técnica possa operar a elevadas taxas de transmissão acima de 100 Gbit~s, se for utilizada amostragem electro-óptica assíncrona antes do receptor. Dessa forma pode ser utilizado um fotodetector de baixo custo e de baixa largura de banda. No capítulo 5 é demonstrada uma técnica para monitoria em simultâneo de vários impedimentos da rede óptica atráves de um novo método para gerar diagramas de análise de desempenho com redes neuronais artificiais. No capítulo 6 o autor demonstra uma técnica para controlo da polarização, totalmente processada no domínio óptico assim como um exemplo de como o processamento totalmente óptico pode cooperar com o monitoria do desempenho óptico.

Abstract:
This thesis presents a large scale numerical investigation of heterogeneous terrestrial optical communications systems and the upgrade of fourth generation terrestrial core to metro legacy interconnects to fifth generation transmission system technologies. Retrofitting (without changing infrastructure) is considered for commercial applications. ROADM are crucial enabling components for future core network developments however their re-routing ability means signals can be switched mid-link onto sub-optimally configured paths which raises new challenges in network management. System performance is determined by a trade-off between nonlinear impairments and noise, where the nonlinear signal distortions depend critically on deployed dispersion maps. This thesis presents a comprehensive numerical investigation into the implementation of phase modulated signals in transparent reconfigurable wavelength division multiplexed fibre optic communication terrestrial heterogeneous networks. A key issue during system upgrades is whether differential phase encoded modulation formats are compatible with the cost optimised dispersion schemes employed in current 10 Gb/s systems. We explore how robust transmission is to inevitable variations in the dispersion mapping and how large the margins are when suboptimal dispersion management is applied. We show that a DPSK transmission system is not drastically affected by reconfiguration from periodic dispersion management to lumped dispersion mapping. A novel DPSK dispersion map optimisation methodology which reduces drastically the optimisation parameter space and the many ways to deploy dispersion maps is also presented. This alleviates strenuous computing requirements in optimisation calculations. This thesis provides a very efficient and robust way to identify high performing lumped dispersion compensating schemes for use in heterogeneous RZ-DPSK terrestrial meshed networks with ROADMs. A modified search algorithm which further reduces this number of configuration combinations is also presented. The results of an investigation of the feasibility of detouring signals locally in multi-path heterogeneous ring networks is also presented.

Abstract:
The continuous growth of traffic demand driven by the brisk increase in number of Internet users and emerging online services creates new challenges for communication networks. The latest advances in Wavelength Division Multiplexing (WDM) technology make it possible to build Transparent Optical Networks (TONs) which are expected to be able to satisfy this rapidly growing capacity demand. Moreover, with the ability of TONs to transparently carry the optical signal from source to destination, electronic processing of the tremendous amount of data can be avoided and optical-to-electrical-to-optical (O/E/O) conversion at intermediate nodes can be eliminated. Consequently, transparent WDM networks consume relatively low power, compared to their electronic-based IP network counterpart. Furthermore, TONs bring also additional benefits in terms of bit rate, signal format, and protocol transparency. However, the absence of O/E/O processing at intermediate nodes in TONs has also some drawbacks. Without regeneration, the quality of the optical signal transmitted from a source to a destination might be degraded due to the effect of physical-layer impairments induced by the transmission through optical fibers and network components. For this reason, routing approaches specifically tailored to account for the effect of physical-layer impairments are needed to avoid setting up connections that don’t satisfy required signal quality at the receiver. Transparency also makes TONs highly vulnerable to deliberate physical-layer attacks. Malicious attacking signals can cause a severe impact on the traffic and for this reason proactive mechanisms, e.g., network design strategies, able to limit their effect are required. Finally, even though energy consumption of transparent WDM networks is lower than in the case of networks processing the traffic at the nodes in the electronic domain, they have the potential to consume even less power. This can be accomplished by targeting the inefficiencies of the current provisioning strategies applied in WDM networks. The work in this thesis addresses the three important aspects mentioned above. In particular, this thesis focuses on routing and wavelength assignment (RWA) strategies specifically devised to target: (i) the lightpath transmission quality, (ii) the network security (i.e., in terms of vulnerability to physical-layer attacks), and (iii) the reduction of the network energy consumption. Our contributions are summarized below. A number of Impairment Constraint Based Routing (ICBR) algorithms have been proposed in the literature to consider physical-layer impairments during the connection provisioning phase. Their objective is to prevent the selection of optical connections (referred to as lightpaths) with poor signal quality. These ICBR approaches always assign each connection request the least impaired lightpath and support only a single threshold of transmission quality, used for all connection requests. However, next generation networks are expected to support a variety of services with disparate requirements for transmission quality. To address this issue, in this thesis we propose an ICBR algorithm supporting differentiation of services at the Bit Error Rate (BER) level, referred to as ICBR-Diff. Our approach takes into account the effect of physical-layer impairments during the connection provisioning phase where various BER thresholds are considered for accepting/blocking connection requests, depending on the signal quality requirements of the connection requests. We tested the proposed ICBR-Diff approach in different network scenarios, including also a fiber heterogeneity. It is shown that it can achieve a significant improvement of network performance in terms of connection blocking, compared to previously published non-differentiated RWA and ICBR algorithms.  Another important challenge to be considered in TONs is their vulnerability to physical-layer attacks. Deliberate attacking signals, e.g., high-power jamming, can cause severe service disruption or even service denial, due to their ability to propagate in the network. Detecting and locating the source of such attacks is difficult, since monitoring must be done in the optical domain, and it is also very expensive. Several attack-aware RWA algorithms have been proposed in the literature to proactively reduce the disruption caused by high-power jamming attacks. However, even with attack-aware network planning mechanisms, the uncontrollable propagation of the attack still remains an issue. To address this problem, we propose the use of power equalizers inside the network nodes in order to limit the propagation of high-power jamming attacks. Because of the high cost of such equipment, we develop a series of heuristics (incl. Greedy Randomized Adaptive Search Procedure (GRASP)) aiming at minimizing the number of power equalizers needed to reduce the network attack vulnerability to a desired level by optimizing the location of the equalizers. Our simulation results show that the equalizer placement obtained by the proposed GRASP approach allows for 50% reduction of the sites with the power equalizers while offering the same level of attack propagation limitation as it is possible to achieve with all nodes having this additional equipment installed. In turn, this potentially yields a significant cost saving.    Energy consumption in TONs has been the target of several studies focusing on the energy-aware and survivable network design problem for both dedicated and shared path protection. However, survivability and energy efficiency in a dynamic provisioning scenario has not been addressed. To fill this gap, in this thesis we focus on the power consumption of survivable WDM network with dynamically provisioned 1:1 dedicated path protected connections. We first investigate the potential energy savings that are achievable by setting all unused protection resources into a lower-power, stand-by state (or sleep mode) during normal network operations. It is shown that in this way the network power consumption can be significantly reduced. Thus, to optimize the energy savings, we propose and evaluate a series of energy-efficient strategies, specifically tailored around the sleep mode functionality. The performance evaluation results reveal the existence of a trade-off between energy saving and connection blocking. Nonetheless, they also show that with the right provisioning strategy it is possible to save a considerable amount of energy with a negligible impact on the connection blocking probability. In order to evaluate the performance of our proposed ICBR-Diff and energy-aware RWA algorithms, we develop two custom-made discrete-event simulators. In addition, the Matlab program of GRASP approach for power equalization placement problem is implemented.

Abstract:
Optical networks form the foundation of today's information infrastructure. Current generation optical networks consist largely of point-to-point electronically transmitted links which switch between nodes and repeaters. There is a trend in optical networking to move from the current generation opaque networks toward transparent networks. Transparent networks use only optical devices, eliminating the costly need for OEO conversions. Unfortunately, transparent networks present a unique challenge in maintaining acceptable signal quality levels. This research is an investigation of RWA algorithms in transparent optical networks. We present RAPTOR, a custom built discrete event program to simulate optical networks. RAPTOR uses its physically aware modules to accurately calculate three of the dominant physical impairments. RAPTOR is fast and multi-threaded. We introduce several new performance metrics. RAPTOR enables us to study transparent optical networks in a unique and realistic manner. We conduct an extensive performance analysis of existing RWA algorithms. We explore many different traffic models, traffic loads, signal quality, and network topologies in a comprehensive fashion. We directly compare the leading RWA algorithms in a manner has not been done before. We studied new RWA algorithms in two fields: Dynamic Programming and Ant Colony Optimization. Our new Dynamic Programming based algorithm has the best overall performance in most scenarios. It is flexible and adapts well to all network conditions we studied. It shows good promise for future optical networks.

Abstract:
Les réseaux de télécommunication transparents constituent une étape de développement des réseaux entièrement électroniques. Les technologies de réseau de données actuelles utilisent déjà activement les fibres optiques et les réseaux transparents dans les réseaux centraux, métropolitains et résidentiels. Toutefois, ces réseaux reposent toujours sur la commutation électronique de paquets (EPS) pour le routage des paquets, qui rend obligatoire pour chaque paquet d'avoir une conversion de signal optique à électronique à optique (OEO). D'autre part, la commutation optique de paquets (OPS), qui semblait remplacer le système EPS, promet depuis longtemps des améliorations en termes de performances et de consommation d'énergie en s'éloignant des conversions OEO; cependant, l'absence de buffers optiques pratiques rendait OPS extrêmement vulnérable aux contentions, entraînant une réduction des performances et empêchant de tirer profit des gains de l'OPS. L'objectif de cette recherche est d'étudier la performance des réseaux avec des commutateurs tout optiques et hybrides, tandis que les activités de transmission côté serveur sont régies par des protocoles de contrôle de transport basés sur des algorithmes de contrôle de congestion (TCP CCA). Nous considérons que l'opération OPS pourrait être activée en utilisant un commutateur hybride, c.a.d. une solution au niveau de l'appareil, ainsi que des TCP CCA spécialement conçus, c.a.d. une solution au niveau du réseau, donnant naissance à des réseaux hybrides à commutation de paquets optique (HOPS). Nous étudions les réseaux de centres de données (DCN) de type OPS, HOPS et EPS associés à différentes TCP CCAs en suivant les trois axes de la performance: débit, consommation d'énergie et latence. En ce qui concerne les TCP CCA, nous considérons non seulement les solutions existantes, mais également celles développées. Si Stop-And-Wait (SAW), Selective Acknowledgment (SACK), SACK modifié (mSACK) et Data Center TCP (DCTCP) sont déjà connus, Stop-And-Wait- Longer (SAWL) est présenté ici et conçu pour tirer le meilleur du HOPS DCN. Il est démontré que les solutions de commutateurs hybrides surpassent de manière significative les commutateurs tout optiques sans buffer et atteignent le niveau de commutateurs tout électroniques en termes de débit du réseau. En termes de consommation d'énergie, les solutions hybrides peuvent économiser jusqu'à 4 fois plus d'énergie de la commutation par rapport aux solutions tout électroniques. De plus, les DCN HOPS peuvent atteindre des latences moyennes à l'échelle des microsecondes, dépassant ainsi les EPS et se situant au même niveau que les OPS. La question de l'introduction de classes de service dans HOPS DCN est examinée: on constate que les règles de commutation spécifiques en commutation hybride peuvent améliorer la performance de certaines classes sans pertes significatives d'autres
Transparent optical telecommunication networks constitute a development step from all-electronic networks. Current data network technologies already actively employ optical fibers and transparent networks in the core, metro, and residential area networks. However, these networks still rely on Electronic Packet Switching (EPS) for packets routing, constituting obligatory for each packet optical-to-electronic-to-optical (OEO) signal conversion. On the other hand, Optical Packet Switching (OPS), seemed to be as replacement of EPS, has long promised performance and energy consumption improvements by going away from OEO conversions; however, the absence of practical optical buffers made OPS highly vulnerable to contention, incurring performance reduction, and getting in the way of profiting from OPS gains. The subject of this research lies in the investigation of the performance of OPS networks under all-optical and hybrid switches, while server-side transmission activities are regulated by Transport Control Protocols based on Congestion Control Algorithms (TCP CCAs). We consider that OPS could be enabled by use hybrid switch, i.e. device-level solution, as well by use of specially designed TCP CCAs, i.e. networklevel solution, giving birth to Hybrid Optical Packet Switching (HOPS) networks. We extensively study OPS, HOPS and EPS types of Data Center Networks (DCN) coupled with different TCP CCAs use by following the next three axes of DCN performance: Throughput, Energy Consumption, and Latency. As for TCP CCAs we consider not only existing but also newly developed solutions. If Stop-And-Wait (SAW), Selective Acknowledgment (SACK), modified SACK (mSACK) and Data Center TCP (DCTCP) are already known to the world, StopAnd-Wait-Longer (SAWL) is newly presented and is designed to bring the best out of the HOPS DCN. As a result, it is shown that hybrid switch solutions significantly outperform bufferless all-optical switches and reach the level of all-electronic switches in DCNs in terms of throughput. In terms of energy consumption, hybrid solutions can save up to 4 times on energy on switching compared to all-electronic solutions. As well HOPS DCNs can exhibit microseconds-scale average latencies, surpassing EPS and performing on the level with OPS. The question of the introduction of Classes of Service to HOPS DCN is also investigated: it was found that class-specific switching rules to hybrid switch can ameliorate the performance of certain classes without almost performance loss in others

This work investigates a technique to encrypt the optical signal for Transparent Optical Network, TON, in order to safeguard the confidentiality and guarantee the security of informations that are transmitted through the Telecommunications Network. The technique is assessed on the physical layer of the reference model for open systems interconnection, OSI, and consists of slicing spectrally optical signal and to apply various attenuations and delays to each of the slices spectral considered. These slices are multiplexed and the resulting signal, which will be propagated by an optical network transparent, it will be ideally unintelligible to eavesdropper who try to steals it. At this point is possible to evaluate the quality of the encryption used by measuring the output of the encoder the bit error rate, BER, the encrypted signal, BERC. In principle, as highest BERC,it will be lowest the probability of an eavesdropper decode the signal. To get to your destination, the signal is received in the decoder circuit, which has the same physical structure of the circuit which encoded the original signal. The application of the factors of attenuation and delay in this distorted signal is adjusted for the reconstruction of optical signal generated by the transmitter. On the output of decoder, performs the measurement of BER of signal decoded, the BERD. Ideally, BERD must be the lowest possible. For technique evaluation, it was simulated, with the version 8.7 of the software VPITransmissionMaker, of company VPIPhotonics Inc, the operation of the devices of cryptography, propagation and the elements of decoded signal. All simulations considered that the spectral slicing was carried out by means of filters with ideal profile. The results indicates that the BERC may reach up to 42% and 24%, to encrypted signals with modulation on-off Keying non return to zero (NRZ-OOK) and differential quadrature phase shift keying (DQPSK) respectively, and that both are free of errors (BERD< 10-15 for the signal NRZ-OOK and BERD< 10-6 for DQPSK modulation) when decoded.

A t?cnica avaliada ? relativa ? camada f?sica do modelo de refer?ncia para interconex?o de sistemas abertos (open systems interconnection, OSI) e consiste em dividir espectralmente um sinal ?ptico e em aplicar diferentes atenua??es e atrasos a cada uma das fatias espectrais consideradas. A seguir essas fatias s?o multiplexadas e o sinal resultante, que ser? propagado por uma rede ?ptica transparente, estar? idealmente inintelig?vel para intrusos que tentem furt?-lo. Nesse ponto ? poss?vel avaliar a qualidade da criptografia utilizada, medindo-se na sa?da do codificador a taxa de erro de bit (bit error rate, BER) do sinal criptografado, BERC. Em princ?pio, quanto maior BERC, menor a probabilidade de um intruso decodificar o sinal. Ao chegar ao seu destino, o sinal ? recebido no circuito decodificador, que possui a mesma estrutura f?sica do circuito que codificou o sinal original. A aplica??o dos fatores de atenua??o e atraso neste sinal distorcido ? ajustada para a reconstru??o do sinal ?ptico gerado pelo transmissor. Na sa?da do decodificador, efetua-se a medi??o da BER do sinal decodificado, BERD. Idealmente, BERD deve ser a menor poss?vel. Para avalia??o da t?cnica, simulou-se, com a vers?o 8.7 do software VPITransmissionMaker, da empresa VPIPhotonics Inc, a opera??o dos dispositivos de criptografia, da propaga??o e dos elementos de decriptografia do sinal. Todas as simula??es consideraram que o fatiamento espectral foi realizado por meio de filtros com perfil ideal. Os resultados indicam que a BERC pode atingir at? 42% e 24%, para sinais codificados com modula??o n?o retorno ao zero com chaveamento on-off (non return to zero on-off keying, NRZ-OOK) e por deslocamento de fase diferencial em quadratura (differential quadrature phase shift keying, DQPSK) respectivamente, e que ambos n?o apresentam erros (BERD< 10-15 para o sinal NRZ-OOK e BERD< 10-6 para a modula??o DQPSK) quando decodificados.
