2. Algoritmo de roteamento Anycast baseado em algoritmos genéticos para redes tolerantes a atrasos e desconexões / Anycast Routing Algorithm Based on Genetic Algorithms for Delay and Disruption Tolerant Networks
DTNs (Delay and Disruption Tolerant Networks) have the potential to interconnect devices and areas of the world that are underserved by traditional networks. The development of these networks can lead to the revolution of the technology information for the population in developing countries which lack infrastructure, especially in remote and rural regions. I

3. Nodes architecture and traffic engineering in optical networks / Arquitetura de nós e engenharia de tráfego em redes ópticas
Integrating telecommunication networks has enlarged the coverage, but has made operations more complex, mainly because of the architecture, formed by various layers. These layers deal with different protocols and transmission rates, as well as electrical and optical signals. The usual alternative of expanding the resources proportionally to the demand is imp

4. Otimização multi-objetivo aplicada à alocação dinâmica de rotas em redes de telecomunicações
The new networking technologies and the Internet difusion produced the data traffic increase in the networks. The quality of service (QoS) requirements for applications also increased and become stricter. Different QoS metrics can be evaluated by applications, for example the delay, the load balance and the packets lost in the communication.Different optimiz

5. Algebraic formulation for modeling hop-by-hop multi-constrained routing algorithms. / Formulação algébrica para a modelagem de algoritmos de roteamento multi-restritivo hop-by-hop.
This work presents a new mathematical structure for paths algebra that allows the convergence analysis of hop-by-hop multi-constrained routing algorithms and, under the traffic engineering and quality of service perspectives in the Generalized Multiprotocol Label Switching (GMPLS) architecture, trustily ensures the aggregation of new routing metrics in a con

6. Future internet architecture to structure and to manage dynamic autonomous systems, internet service providers and customers
In recent years, the problem of dynamic networks has received a great deal of attention from the network research community. This problem consists in providing for the Internet architecture a set of mechanisms, such as addressing, information management and information forwarding, which support mobile information and mobile entities (Autonomous Systems, Inte

7. Performance analysis of IP traffic grooming over WDM networks with variable granularity flows. / Análise de desempenho da agregação de tráfego IP em redes WDM com variação da granularidade dos fluxos.
The present work covers the IP traffic grooming strategies in optical WDM networks. Using an entire wavelength to transport an individual traffic flow in a WDM network is inefficient. The problem known as traffic grooming consists in the multiplexing of different traffic flows in a single wavelength within a lightpath. The allocation of multiple traffic flow

8. Architecture and implementation of a topological information and traffic engineering service to RWA systems / Arquitetura e implementação de um serviço de informações topologicas e de engenharia de trafego para sistemas RWA
GMPLS-controlled all-optical networks are the promise to handle the increasing volume of IP traffic. The GMPLS routing and signaling protocols, mainly OSPF and RSVP, work in such a way that the route calculation for optical circuits does not take into account the wavelength (label) availability. This is not optimal in terms of network resources usage and blo

9. Esquemas de proteção e conversão de comprimento de onda em redes opticas WDM / Protection schemes and wavelength conversion in WDM optical networks
This work examines the blocking reduction with the use of wavelength converters and some protection schemes in optical networks. Sub-Graph Routing Protection, a protection method that creates different failure-dependent protection paths for each connection is presented. Some schemes were proposed and compared, aiming at eliminating unnecessary connection rea

10. A methodology for provisioning and differentiation of optical QoS in FWN impaired transparent optical networks / Uma abordagem para aprovisionamento e diferenciação de QoS optico na presença de FWM em redes opticas transparentes
This Thesis proposes methodologies for differentiated optical QoS in a multi-client scenario, in which client networks (e.g. IP/MPLS and SDH) dynamically request lightpaths from a transparent optical network in which Four-Wave Mixing (FWM) imposes crosstalk among lightpaths. In order to meet Optical Service Level Agreement (OSLA), it is proposed an integrate

11. Planejamento de redes WDM com proteção para caminhos opticos
This dissertation is a study about the initial traffic deployment in wavelength-routed WDM (Wavelength Division Multiplexing) optical networks with path protection. We make an introduction of the key technologies and the major network planning aspects. We introduce some architectures for transport provisioning to various client network architectures. The RWA
