NeTS-NR: Strategies to save energy in the internet

国家科学基金会网络技术和系统（NeTS）CISE/CNS评审分析和建议提案编号：0435328 PI： Suresh Singh机构： 波特兰州立大学策略，以节省能源在互联网摘要：这项建议提出了一个案例，使用睡眠作为一种方式，以减少能源消耗的互联网设备。这样做的好处包括，减少能源需求，这将促进互联网的全球部署，使互联网在不可靠的电力供应中更加可靠，并使互联网的受灾部分能够在可用的UPS电源上继续运行更长时间（不间断电源）。这里提出的减少能源消耗的方法是使用包-级别信息，以使交换机和路由器内的硬件组件进入睡眠状态。重点是在一个组织的自治系统（AS）的背景下，提供了许多节能的机会，节能。研究的挑战包括开发睡眠算法，在睡眠状态下保持网络级QoS（服务质量），以及分析睡眠对当前互联网协议的影响。研究这些问题的方法将依赖于测量，模拟和原型，这项工作的影响将是减少全国互联网设备的能耗35% -55%。 此外，这项新技术将使美国互联网设备制造商能够在能源成本远高于美国的海外市场扩大其市场。这项工作的预期成果包括可以直接用于未来互联网设备的特定睡眠算法，演示关键概念的原型设备，以及在互联网相关研究的主要场所发表的研究论文。

National Science FoundationNetwork Technologies and Systems (NeTS)CISE/CNSReview Analysis and RecommendationProposal Number: 0435328PI: Suresh Singh Institution: Portland State UniversityTitle: Strategies to Save Energy in the Internet Abstract: This proposal makes a case for using sleeping as a way to reduce the energy consumption of internet devices. The benefits of doing so include, reducing energy needs which will promote a more global deployment of the internet, making the internet more reliable in the presence of unreliable power supply, and enabling disaster-hit portions of the internet to continue functioning for longer periods on the available UPS power (Uninterruptable Power Supply).The approach for reducing the energy consumption proposed here is to use packet-level information to put hardware components within switches and routers to sleep. The focus is on energy-conservation within the context of an organization's Autonomous System (AS) which provides many energy-saving opportunities. The research challenges include developing algorithms for sleeping, maintaining network-level QoS (Quality of Service) despite sleeping, and analyzing the impact of sleeping on current internet protocols.The methodology used to study these problems will rely on measurements, simulation, and prototyping.The impact of this work will be to reduce the energy consumption by internet devices nationwide by between 35% - 55%. In addition, the new technology will enable American manufacturers of internet equipment to expand their market abroad where energy costs a far more than in the US.The expected results of this work include specific sleeping algorithms that can be directly employed in future internet devices, a prototype device that demonstrates the key concepts, and research papers published in major venues for internet related research.
