Genetic algorithm for the topological design of survivable optical transport ne...
Morais, Rui Manuel; Pavan, Claunir; Pinto, Armando Nolasco; Requejo, CristinaWe develop a genetic algorithm for the topological design of survivable optical transport networks with minimum capital expenditure. Using the developed genetic algorithm we can obtain near-optimal topologies in a short time. The quality of the obtained solutions is assessed using an integer linear programming model. Two initial population generators, two selection methods, two crossover operators, and two popu...
Generating realistic optical transport network topologies
Pavan, Claunir; Morais, Rui Manuel; Rocha, José R. Ferreira da; Pinto, Armando NolascoWe address the problem of generating physical realistic optical transport network topologies. This type of network has characteristics that differ from scale-free networks, such as the Internet. Based on the analysis of a set of real transport topologies, we identify and assess relevant characteristics. Amethod to generate realistic topologies is proposed. The proposed method is validated by comparing the chara...
Dimensioning of multilayer optical networks
Pavan, ClaunirEste trabalho apresenta um estudo sobre o dimensionamento de redes ópticas, com vistas a obter um modelo de dimensionamento para redes de transporte sobreviventes. No estudo utilizou-se uma abordagem estatística em detrimento à determinística. Inicialmente, apresentam-se as principais tecnologias e diferentes arquitecturas utilizadas nas redes ópticas de transporte. Bem como os principais esquemas de sobrevivên...
