Transferências de Dados em Massa Sensíveis ao Consumo Energético em Redes Ópticas Elásticas

Energy consumption in core networks is currently impacted by Bulk Data Transfer (BDT) applications among the major Internet Data Centers (CDs). This is because these applications consume most of the available resources and do so for long periods of time. Due to the increase in network traffic that occurs every year, one of the key challenges for cloud service providers is energy efficiency. To serve the growing demand, the Elastic Optical Networks (EON) paradigm has been proposed with the objective of meeting requests with greater flexibility, making better use of the frequency spectrum. This paper proposes the Energy Efficient Aware-BDT in EON (EEABE) solution, an energy efficient aware Routing and Spectrum Allocation (RSA) algorithm for performing inter-CD BDT (ICD), which is capable of scaling BDT requests and implementing the sleep mode technique to reduce the power consumption of the switching elements in the optical network.
