FYI ---------- Forwarded message --------- *Call for Papers* *Fourth International Workshop on Green and Sustainable Networking (GreenNet 2025) */In conjunction with IEEE International Conference on Communication (ICC) 2025, 8–12 June 2025 // Montreal, Canada/ Energy efficiency and sustainability have become of paramount importance in all human activities, including the information and communication technology sector. The trade-off between availability, resiliency, programmability, and energy efficiency of networks and services is a key challenge for the next decade and monitoring methods and metrics for power consumption, energy efficiency, as well as sustainability are important, as well as benchmarking of solutions based on well-defined KPIs. For that reason, the goal of the GreenNet Workshop is to address emerging concepts and challenges related to energy efficiency and sustainability for networked services. An improved sustainability in all parts of the network in a time of increasing AI/ML usage, evolution of different novel network access technologies, the spreading of edge computing and micro-data centers and the demand in computational and data transport capacity across the edge-cloud continuum is essential.
