Abstract

Ethernet is one of the first computer networking technologies for which a standard has been developed to improve its energy efficiency. The Energy Efficient Ethernet (IEEE 802.3az) standard was approved in 2010 and is expected to enable savings of several Terawatt hours (TWh) per year. As switches that implement the standard become available and are deployed, it is important to understand how their energy consumption depends on the number of active ports and their traffic. In this paper the energy consumption of small Energy Efficient Ethernet switches is analyzed in several experiments and based on the results a model for the energy consumption of Energy Efficient Ethernet switches is proposed. The model can be used to predict the energy savings when deploying the new switches and also for research on further energy saving techniques such as energy efficient routing or dynamic link shutdown.
节能以太网交换机的能耗模型
以太网是最早为提高其能源效率而制定标准的计算机网络技术之一。节能以太网(IEEE 802.3az)标准于2010年获得批准,预计每年可节省数太瓦时(TWh)。随着实现该标准的交换机的可用性和部署,了解它们的能耗如何取决于活动端口的数量及其流量是很重要的。本文通过多次实验分析了小型节能以太网交换机的能耗,并在此基础上提出了节能以太网交换机的能耗模型。该模型可用于预测部署新交换机时的节能效果,也可用于研究进一步的节能技术,如节能路由或动态链路关闭。
