最近，计算机科学、电信和控制系统领域的不同团体都在为数据传输和网络管理设计节能解决方案方面投入了巨大的努力。本文搭配沿着这条研究路线，并提出了一种新的能源效率的策略设想的以太网网络。所提出的策略，它利用了IEEE 802.3az的以太网标准（称为节能以太网）的修正案提供的机会是基于预测未来的流量从当前的数据流的分析的可能性。与这种动态预测的结果一致，以太网链路可以被强制进入低功耗状态可变的间隔。理论界推导出详细的性能数字如何取决于设计的策略和规模的流量负载的参数。此外，与真实的和合成的流量轨迹进行了仿真结果证明了该策略的有效性，这导致相当大的能量节省的成本只有有限的有界延迟的数据传输。
Recently, different communities in computer science, telecommunication, and control systems have devoted a huge effort towards the design of energy efficient solutions for data transmission and network management. This paper collocates along this research line and presents a novel energy efficient strategy conceived for Ethernet networks. The proposed strategy, which exploits the opportunities offered by the IEEE 802.3az amendment to the Ethernet standard (known as energy efficient Ethernet) is based on the possibility of predicting the future traffic from the analysis of the current data flow. In agreement with the results of such a dynamic prediction, Ethernet links can be forced into a low power consumption state for variable intervals. Theoretical bounds are derived to detail how the performance figures depend on the parameters of the designed strategy and scale with respect to traffic load. Furthermore, simulation results carried out with both real and synthetic traffic traces are presented to prove the effectiveness of the strategy, which leads to considerable energy savings at the cost of only a limited bounded delay in data delivery.
