EWA – an adaptive algorithm using watermarks for energy saving in IP-over-WDM networks

We propose an adaptive algorithm, the Energy Watermark Algorithm (EWA), to reduce the power consumption of Internet Protocol (IP)-over-Wavelength Division Multiplexing (WDM) networks. After presenting a network model and a detailed description of the EWA, we perform a sensitivity analysis and evaluate the performance of the algorithm considering real… (More)
