1. Algoritmos RWA para redes ópticas transparentes considerando limitações da camada física / RWA algorithms for optical transparent networks considering physical impairments
With the proliferation of new multimedia services such as VoIP and IP-TV, an increasing demand for high rates of data transfer is being seen. Thus, the demand on the core of the network is continuously growing, so its capacity must increase in the same ratio to provide a reliable service to end users. The Transparent Optical Networks with WDM appears as a so

2. Algoritmo de RWA com considerações de sobrevivência baseado em heurística-algoritmo genético para redes IP/WDM / RWA algorithm with surviability considerations in heuristics-genetic algorithm to IP/WDM networks
This thesis describes the creation, development and application of a novel hybrid Heuristic-GA algorithm, for the optimization of dynamic routing and wavelength assignment mechanisms with survivability (S-DRWA), guided to the reserve of capacity based on sharing routes protection and applied in IP transport network over WDM. In this joint operation, heuristi

3. 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

4. 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

5. MULTICAST COMMUNICATION IN OPTICAL IP INTERNETWORKS / DIFUSÃO SELETIVA EM INTER-REDES IP BASEADAS EM REDES ÓPTICAS
Multicast communication and recent advances in optical technology, most specifically in Wavelength Division Multiplexing (WDM), allied with the consolidation of IP as the dominant protocol of convergent networks, offer new perspectives for the next generation Internet. This thesis utilises these technologies to propose a set of adaptations, called MIRROR, to

6. 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
