1. Integrated planning of optical networks - optimization and protection in virtual and physical topologies / Planejamento integrado de redes óticas - otimizção e proteção nas topologias virtual e física
This work aims to design integrated optical networking, which in the literature, due to complexity, is divided into Virtual Topology Design (VTD) and Physical Topology Design (PTD). Linear programming and heuristics are proposed to maximize the utilization of the network, so that for future demands, the same network may remain able to meet the requests, with

2. Contribuições para a análise e simulação de redes ópticas: aspectos de Engenharia de Tráfego, restauração dinâmica e conversão de comprimentos de onda / Contributions for the analysis and simulation of optical networks: aspects of traffic engineering, dynamic restoration and conversion of wavelenghts
The Wavelength Division Multiplexing (WDM) technology as well as both the introduction of all optical OXCs (Optical Cross Connect) and OADMs (Optical Add/Drop Multiplexer) may provide the optical network with the networking function, i.e, the capacity to manipulate wavelengths in order to implement their routing. This possibility implies a new type of relati

3. A policy-based architecture for fault management in optical networks / Uma arquitetura baseada em politicas para gerencia de falhas em redes opticas
In these last few years, optical networking technology has been considered as a solution for bottlenecks found in today s networks. Each optical fiber is capable to have from ten to hundreds of optical channels that operate at rates from 51 Mb/s to ten of terabits per second. These channels are important elements in the composition of lightpaths, the default

4. Otimização de Tráfego: Roteamento e Critérios de Proteção em Redes Ópticas
Nowadays, many researchers of optical networks concentrate their studies on how to achieve the implementation of all links in the network, by using only the optical domain. This concept allows the transmission, switching and reception of all optical signals without eletronic conversion, and at the same time, increases the transmission speeds and the correspo

5. PROTECTION E RESTORATION, TOGETHER WITH NODE ADDRESSING AND TMN MANAGEMENT FOR IP OVER DWDM OPTICAL NETWORKS BY USING PHYSICAL LAYER / PROTEÇÃO, RESTAURAÇÃO, ENDEREÇAMENTO E GERENCIAMENTO TMN NA CAMADA FÍSICA PARA APLICAÇÕES IP SOBRE DWDM
The objective of this work is to explore the possibilities of built-in intelligence embedded in the physical layer of an Optical Telecommunications Network, aiming at its future applications. The use of RF subcarriers - introduce above the optical payload through Mach-Zehnder modulators -, associated with multiple acess technologies, allows for protection, r
