Agregação Dinâmica de Fluxos com Duração Conhecida em Redes WDM através de Balanceamento de Tráfego
Resumo
Neste trabalho, propõe-se uma nova abordagem para agregação dinâmica de tráfego com duração conhecida que utiliza uma função de custo que induz ao balanceamento de tráfego em redes ópticas em malha WDM. A principal contribuição da abordagem proposta é permitir uma melhor distribuição da carga na rede reduzindo a taxa de rejeição das demandas. Para avaliar o desempenho do algoritmo proposto foram realizadas comparações com a política de HTA original. Os resultados demonstram melhorias significativas na probabilidade de bloqueio das conexões, o que evidencia os benefícios da abordagem proposta.Referências
