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.

随着对生态和经济驱动因素的关注，高能效流程日益成为信息和通信技术公司的关键优先事项。虽然在某些情况下，信息和通信技术的使用可能有益于环境(例如，通过减少行程和采用更有效的业务程序)，但各国越来越意识到电信公司的能源消耗增长很大。例如，2007年英国电信的用电量占英国总用电量的0.7%。特别是，如果连接的设备数量和互联网带宽达到一两个数量级，那么预测的未来增长将导致能源消耗相应增长，这是不切实际的。因此，法规可能很快就会出台，特别是如果政府强制向碳中性迈进的话。因此，申请人认为，这项提案对于寻求确定目前由于已知的环境问题而对信通技术性能造成的限制，然后开发新的信通技术技术以提高性能具有重要意义。特别是，他们认为，通过创新使用可再生能源和开发在硬件上运行的新架构、协议和算法，可以取得实质性进展，这本身将允许大幅减少能源消耗。这将大大背离公认的做法，即提供信息和通信技术服务是为了满足日益增长的需求，而不考虑供需相对位置对能源的影响。因此，在这个项目中，我们创新性地建议考虑优化信息和通信技术服务的动态布局，同时考虑到生产者和消费者的不同能源成本。当今网络中的能源消耗通常高度受限于交换和路由中心。因此，在该项目中，我们将考虑在选择最佳可再生能源供应的中心之间阻断数据传输，因为电力传输损耗往往会使向城市(城市中的数据中心/交换节点)输送电力变得没有吸引力。太阳能和风能等可变的可再生能源对ICT安装和网络设计提出了新的挑战，因此本项目还将研究灵活的块数据路由器功耗的创新方法来解决这一影响。我们沿着三个轴应对挑战：(I)我们寻求通过解决在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ICT基础设施架构，并(随时间变化)最大限度地降低能源成本。在这里，架构将利用可用的新硬件来实现低能耗操作。(Ii)我们寻求设计新的协议和算法，使通信系统能够根据用户需求和能源供应来调整其速度和功耗。(Iii)我们建立在硬件最新进展的基础上，这些进展允许以大大低于电子技术的能量水平进行数据块路由，并确定硬件配置(首次使用芯片监控)以支持这些动态能源和通信需求。这里将开发新的网络组件，例如，利用最近在开发较低功率路由硬件方面取得的重大进展，对于ns块交换时间，具有大约1 mW/Gb/S的路由功率级别。为了确保成功，不同的公司将利用他们的专业知识：英国电信、爱立信、新西兰电信、思科和BBC将在支持网络架构开发、提供实验支持和流量跟踪以及帮助标准开发方面发挥关键作用。Solarflare、博通、思科和BBC将支持我们的协议和智能交通解决方案。Avago、博通和Oclaro将在硬件开发中发挥关键作用。
