Abstract
The global demand for data and energy continues to surge, necessitating efficient power utilization in data transmission networks. This thesis investigates methods to reduce power conversion losses in modern network routers by optimizing their Power Supply Units (PSUs). The study evaluates energy savings achieved through deploying higher-efficiency PSUs and reducing redundancy by op- erating routers on a single PSU. Utilizing empirical data from a Cisco Nexus 9336C-FX2 switch and large-scale datasets from ETH’s SWITCH network, the analysis reveals substantial underutilization of PSUs, leading to inefficiencies. The findings highlight the critical role of PSUs in sustainable network energy management, advocating for improved standards and practices to achieve greener digital infrastructures.
