Reducing the energy consumption of wired networks has become a key concern for manufacturers of network equipment and network providers. In this paper, we propose an energy-efficient data transfer framework that uses advance bandwidth provisioning and on/off algorithms to put unused nodes of wired networks into sleep mode. This framework is termed as High-level Energy-awaRe Model for bandwidth reservation in End-to-end networkS (HERMES). We explore centralized, decentralized and clustered approaches for managing network resources and bandwidth reservations in this framework. By applying these approaches to HERMES, we evaluate via simulation their efficiency in terms of performance and energy consumption.
