Abstract
Current trends on traffic growth oversee a steady increase of video streaming services, and the subsequent development of the associated infrastructure to allocate and distribute such contents. One of the operational costs associated to this infrastructure is the power bill. Therefore any mechanism used to decrease it, reducing also the carbon footprint associated to it, is welcome. In this work we investigate the suitability of the recently standardized IEEE 802.3az Energy Efficient Ethernet (EEE) for video traffic generated by video-streaming servers. The conclusion of the analysis is positive about the achievable energy savings, due to the inherent features of traffic patterns of video-streaming servers which help reducing the number of transitions between active and low-power modes in EEE. 2012 Elsevier B.V.

Postdoctoral Researcher
Tito Raúl Vargas Hernández graduated in Telecommunications Engineering from Universidad Santo Tomás (USTA), Bucaramanga, Colombia, in 2003. He received the M.Sc. in Telematics Engineering in 2007 and the PhD in Telecommunications in 2023 from the Universitat Politècnica de València (UPV). He worked with the COMM group at iTEAM from 2005 to 2010 and has been a lecturer and researcher at USTA since 2010. In 2022 he joined iTEAM as a research engineer, where he is now a postdoctoral researcher. His research covers multimedia distribution over IP/optical networks, energy-efficient Ethernet, QoS in high-speed networks and the Internet of Things.
