Abstract:
The global data center and networking infrastructure is projected to become the largest energy consumer by 2025,with high energy consumption contributing significantly to the climate due to greenhouse gas emissions. The trend of increased digitization accelerated this further, in particularly by Virtual Private Network and Video Conferencing network traffic, leading to higher CO2 emissions. In this paper, we address this challenge by analyzing and reducing the energy consumption of a secure remote working system. We propose a custom clock boosting mechanism using Dynamic Voltage and Frequency scaling. Our two implementations, utilizing Extended Berkeley Packet Filter and eXpress Data Path, passively listen for new Transmission Control Protocol connections and adjust Central Processing Unit frequency when new employees connect. During idle periods, the frequency is minimized. Through this approach, we achieve up to 28% reduction in energy consumption during high load scenarios, while maintaining virtually no impact on consumption during idle phases. Additionally, the Quality of Service is improved, validating the effectiveness of our strategy.
