Reducing the energy consumption of network equipment has been both driven by a need to
reduce the ecological footprint of the cloud as well as the immense energy costs of data
centers. As data centers, core networks and consequently, the cloud constantly increase in
size, their energy consumption should be mitigated. Ethernet, the most widely used access
network still remains the biggest communication technology used in core networks and
cloud infrastructures. The Energy-Efficient Ethernet or EEE standard introduced by IEEE
in 2010, aims to reduce the energy consumption of EEE ports by transitioning Ethernet
ports into a low power mode when traffic is not present. This research aims to assess the
benefits of deploying EEE and create a power consumption model for network switches
with and without EEE. Our measurements reveal that the energy savings from EEE are not
sufficiently significant in medium to small sized networks. However, energy savings are at
maximum when the network equipment have a lot of ports and traffic has large downtimes.
Hence, we believe that the best use case for EEE is in medium-large computer networks
where the equipment is very large and the traffic has a lot of downtime.
