随着连接internet的终端主机数量的不断增加，对高性能的端到端网络提出了更高的要求，这也导致了网络能耗的增加。我们的工作是处理专用网络的能量消耗问题，带宽供应和预先预留网络设备用于大数据传输。首先，我们提出了这种网络的端到端能量成本模型，该模型描述了所有交叉设备传输所消耗的能量。然后使用该模型开发一个完整的节能框架，适用于专用网络上的批量数据传输。该框架允许在特定时间段关闭未使用的网络部分以节省能源。该框架还赋予了预测算法以避免无用的关闭，并具有自适应调度管理以优化传输的能量使用。通过网络仿真，我们表明，在给定的负载和拓扑结构下，与没有能量管理系统的当前方法相比，所提出的框架可以实现35%的节能。
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. Our 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, we 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. This framework is also endowed with prediction algorithms to avoid useless switching off and with adaptive scheduling management to optimize the energy used by the transfers. Through network simulations, we show that, under given load and topology, the proposed framework can achieve 35% energy savings compared to the current approach, with no energy-management system.
