Abstract

One of the most important challenges of this century will be to minimise as much as possible the energy consumption of the worldwide digital infrastructure to have a significant contribution on our emissions of CO2 reduction since energy consumption and emission of CO2 are directly linked. Therefore, after an introduction (part 1), in part 2 of this paper, we will describe the status of the worldwide production of electricity, the contribution of information and communications technology (ICT) in terms of electricity consumption, and the identification of the critical network segments that can have a significant environmental impact. In part 3, we will focus on the data centres and core services that represent important network segments responsible for the largest emission of CO2. In part 4, we will address the access and aggregation part, which represents the second important network segment to optimise. Part 5 will focus on the home networking and enterprise. And before an estimation of the energy savings obtained when adopting the innovations proposed, the impact of the vertical market will be discussed in part 6. Finally, the conclusion (part 7) will summarise the results and perspectives will be proposed to complete the analysis.

为信息通信技术和垂直市场打造更环保的数字基础设施
本世纪最重要的挑战之一将是尽可能减少全球数字基础设施的能源消耗,以对我们的二氧化碳减排做出重大贡献,因为能源消耗和二氧化碳排放是直接相关的。因此,在引言(第1部分)之后,在本文的第2部分,我们将描述全球电力生产的现状,信息和通信技术在电力消耗方面的贡献,以及确定可能对环境产生重大影响的关键网络部分。在第3部分中,我们将重点关注数据中心和核心服务,它们代表了造成最大二氧化碳排放的重要网络部分。在第4部分中,我们将讨论访问和聚合部分,它代表了要优化的第二个重要网段。第5部分将侧重于家庭网络和企业。在估计采用所提出的创新所节省的能源之前,第6部分将讨论垂直市场的影响。最后,结论(第7部分)将总结结果,并提出完成分析的观点。

期刊介绍: Annals of Telecommunications is an international journal publishing original peer-reviewed papers in the field of telecommunications. It covers all the essential branches of modern telecommunications, ranging from digital communications to communication networks and the internet, to software, protocols and services, uses and economics. This large spectrum of topics accounts for the rapid convergence through telecommunications of the underlying technologies in computers, communications, content management towards the emergence of the information and knowledge society. As a consequence, the Journal provides a medium for exchanging research results and technological achievements accomplished by the European and international scientific community from academia and industry.
