The ever increasing number of Internet-connected end-hosts calls for high-performance end-to-end networks, which in turn leads to an increase in the energy consumed by the networks. The authors' work deals with the energy-consumption issue in dedicated networks with bandwidth provisioning and in-advance reservations of network equipments for Bulk Data transfers. First, they propose an end-to-end energy-cost model of such networks, which describes the energy consumed by a transfer for all the crossed equipments. This model is then used to develop a complete energy-efficient framework adapted to Bulk Data Transfers over dedicated networks. This framework enables switching unused network portions off during certain periods of time to save energy.
