Energy consumption is becoming a fundamental topic also for telecommunication networks, where the implementation of "green" infrastructures is required. In this paper, we report a numerical investigation about energy saving in a transport network both exploiting the transmission properties that permit to reduce the number of in-line equipments (optimizing wavelength path assignment) and switching off optical links when the traffic load decreases. In particular, we investigate a European transport network based on N × 40 Gbit/s transmission and the Italian network based on the M × 10 Gbit/s transmission. © 2010 Elsevier B.V.

Abstract
Energy consumption is becoming a fundamental topic also for telecommunication networks, where the implementation of "green" infrastructures is required. In this paper, we report a numerical investigation about energy saving in a transport network both exploiting the transmission properties that permit to reduce the number of in-line equipments (optimizing wavelength path assignment) and switching off optical links when the traffic load decreases. In particular, we investigate a European transport network based on N × 40 Gbit/s transmission and the Italian network based on the M × 10 Gbit/s transmission. © 2010 Elsevier B.V.
