MOTIVATION
Energy efficiency and sustainability have become of paramount importance in all human activities. Regarding ICT, it has been long recognized that its impact on helping reduce the carbon footprint of other activities can be significant; then, it would be odd if the same principle would not apply to ICT itself. In particular, computing, communications and networking are relevant activities in this context, whose impact is absolutely non-negligible. The concept of Green Computing and Networking is currently gaining additional momentum with the growth in the number of networked applications in all vertical sectors, in the number of users and in the amount of traffic they generate. The pervasiveness of mobile networks in 5G and their evolution toward 6G, the spreading of edge computing and micro-data centers and the demand in computational and data transport capacity across the edge-cloud continuum are all factors that further contribute to making energy efficiency a fundamental aspect of future networks.

GOALS
The goal of the GreenNet Workshop is to address emerging concepts and challenges related to energy efficiency and sustainability for networked services, by pursuing sustainability in the context of ongoing developments such as 5G and beyond, 6G, usage of AI/ML or distributed ledger solutions and with different network access technologies. To this aim, the Workshop will also address advanced traffic and power models, as well as management and control strategies, along with Application Programming Interfaces (APIs), to be used for the lifecycle management and optimization of Physical and Virtual Network Functions, the creation and dynamic reconfiguration of network slices, and the balance between sustainability in terms of energy efficiency and performance. Furthermore, the goal is to not only consider an energy efficient and sustainable access network but complete network, monitoring, and management solutions from data generation to data processing and further usage. The trade-off between availability, resiliency, programmability, and energy efficiency is a key challenge. 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.
