项目摘要

Energy efficient processes are increasingly key priorities for ICT companies with attention being paid to both ecological and economic drivers. Although in some cases the use of ICT can be beneficial to the environment (for example by reducing journeys and introducing more efficient business processes), countries are becoming increasingly aware of the very large growth in energy consumption of telecommunications companies. For instance in 2007 BT consumed 0.7% of the UK's total electricity usage. In particular, the predicted future growth in the number of connected devices, and the internet bandwidth of an order of magnitude or two is not practical if it leads to a corresponding growth in energy consumption. Regulations may therefore come soon, particularly if Governments mandate moves towards carbon neutrality. Therefore the applicants believe that this proposal is of great importance in seeking to establish the current limits on ICT performance due to known environmental concerns and then develop new ICT techniques to provide enhanced performance. In particular they believe that substantial advances can be achieved through the innovative use of renewable sources and the development of new architectures, protocols, and algorithms operating on hardware which will itself allows significant reductions in energy consumption. This will represent a significant departure from accepted practices where ICT services are provided to meet the growing demand, without any regard for the energy consequences of relative location of supply and demand. In this project therefore, we propose innovatively to consider optimised dynamic placement of ICT services, taking account of varying energy costs at producer and consumer. Energy consumption in networks today is typically highly confined in switching and routing centres. Therefore in the project we will consider block transmission of data between centres chosen for optimum renewable energy supply as power transmission losses will often make the shipping of power to cities (data centres/switching nodes in cities) unattractive. Variable renewable sources such as solar and wind pose fresh challenges in ICT installations and network design, and hence this project will also look at innovative methods of flexible power consumption of block data routers to address this effect. We tackle the challenge along three axes: (i) We seek to design a new generation of ICT infrastructure architectures by addressing the optimisation problem of placing compute and communication resources between the producer and consumer, with the (time-varying) constraint of minimising energy costs. Here the architectures will leverage the new hardware becoming available to allow low energy operation. (ii) We seek to design new protocols and algorithms to enable communications systems to adapt their speed and power consumption according to both the user demand and energy availability. (iii) We build on recent advances in hardware which allow the block routing of data at greatly reduced energy levels over electronic techniques and determine hardware configurations (using on chip monitoring for the first time) to support these dynamic energy and communications needs. Here new network components will be developed, leveraging for example recent significant advances made on developing lower power routing hardware with routing power levels of approximately 1 mW/Gb/s for ns block switching times. In order to ensure success, different companies will engage their expertise: BT, Ericsson, Telecom New Zealand, Cisco and BBC will play a key role in supporting the development of the network architectures, provide experimental support and traffic traces, and aid standards development. Solarflare, Broadcom, Cisco and the BBC will support our protocol and intelligent traffic solutions. Avago, Broadcom and Oclaro will play a key role in the hardware development.

对于ICT公司而言，节能过程越来越重要，对生态和经济驱动因素都引起了人们的关注。尽管在某些情况下，ICT的使用可能对环境有益（例如，通过减少旅程并引入更有效的业务流程），但各国越来越意识到电信公司能源消耗的大幅增长。例如，在2007年，BT消耗了英国总使用量的0.7％。尤其是，如果连接设备数量的未来增长以及一个或两个数量级的互联网带宽，如果它导致能源消耗的相应增长，则不可行。因此，法规可能很快就会出现，特别是如果政府要求朝着碳中立行动。因此，申请人认为，由于已知的环境问题，该提案在寻求对ICT绩效的当前限制方面非常重要，然后开发了新的ICT技术以提供增强的性能。他们特别认为，可以通过创新的可再生资源以及在硬件上运行的新建筑，协议和算法的开发来实现实质性进步，这本身将大大减少能源消耗。这将与公认的实践有很大的不同，在这种实践中，提供ICT服务以满足不断增长的需求，而无需考虑相对位置的供应和需求的能源后果。因此，考虑到生产者和消费者的各种能源成本，我们在此项目中进行了创新的建议，以考虑对ICT服务的优化动态放置。当今网络中的能源消耗通常高度限制在切换和路由中心中。因此，在项目中，我们将考虑选择以最佳可再生能源供应的中心之间的数据传输，因为电力传输损失通常会使电力运送到城市（城市中的数据中心/切换节点）没有吸引力。可变的可再生资源（例如太阳能和风能）在ICT装置和网络设计中构成了新的挑战，因此，该项目还将着眼于弹性消耗块数据路由器的创新方法，以解决此效果。我们沿三个轴解决了挑战：（i）我们试图通过解决生产者和消费者之间放置计算和通信资源的优化问题来设计新一代的ICT基础架构架构，并具有最小化能源成本的（时间变化）限制。在这里，体系结构将利用新的硬件可用来允许低能操作。（ii）我们试图设计新的协议和算法，以使通信系统能够根据用户需求和能源可用性调整其速度和功耗。（iii）我们基于硬件的最新进展，允许在电子技术上大大降低能量水平的数据路由，并确定硬件配置（首次使用芯片监控），以支持这些动态的能量和通信需求。在这里将开发新的网络组件，例如利用在开发较低功率路由硬件的最新重要进展中，对于NS块切换时间，路由电源水平约为1 mW/gb/s。为了确保成功，不同的公司将参与其专业知识：BT，爱立信，新西兰电信，思科和BBC将在支持网络体系结构的开发，提供实验性支持和交通迹线以及援助标准的开发方面发挥关键作用。 Solarflare，Broadcom，Cisco和BBC将支持我们的协议和智能交通解决方案。 Avago，Broadcom和Oclaro将在硬件开发中发挥关键作用。
