“…Our model is different from previously proposed analytical models of EEE [32,33,34] in several aspects. Firstly the focus is to model the entire switch compared to an individual PHY as in previous models.…”

The access network is believed to account for 70-80% of the overall energy consumption of wired networks, attributable in part to the large number of small and inefficient switches deployed in typical homes and enterprises. In order to reduce the per-bit energy consumption of such devices, the Energy Efficient Ethernet (EEE) standard was approved as IEEE 802.3az in 2010 with the aim of making Ethernet devices more energy efficient. However, the potential for energy savings, and their dependence on traffic characteristics, is poorly understood. This paper undertakes a comprehensive study of the energy efficiency of EEE, and makes three new contributions: First, we perform extensive measurements on three commercial EEE switches, and show how their power consumption profile depends on factors such as port counts, traffic loads, packet sizes, and traffic burstiness. Second, we develop a simple yet powerful model that gives analytical estimates of the power consumption of EEE switches under various traffic conditions. Third, we validate the energy savings via experiments in typical deployment scenarios, and estimate the overall reduction in annual energy costs that can be realized with widespread adoption of EEE in the Internet.

“…However, the buffer size and the coalescing timeout setting strongly affect the trade-off in EEE performance. Since then, several works addressed modeling and performance analysis of EEE based on various traffic parameters and with and without consideration to packet coalescing [133][134][135][136][137][138][139]. In [133] authors provide an evaluation of static and dynamic coalescing for EEE in which buffer size and timeout are fixed (static) and adapted to traffic pattern (dynamic).…”

Summary-Energy consumption of large-scale networks has become a primary concern in a society increasingly dependent on information technology. Novel solutions that contribute to achieving energy savings in wired networks have been proposed to mitigate ongoing and alarming climate change and global warming. A detailed survey of relevant power-saving approaches in wired networks is presented here. We give a special focus on carrier-grade networks. At first we perform a comprehensive study of communication infrastructures regarding energy saving. Then, we highlight key issues to enable green networks, ranging from network design to network operation. After that, we present the major contributors to power consumption in wireline networks. Afterwards, we survey, classify, and compare the main energyaware methods and mechanisms that are the most appropriate for improving the energy efficiency of carrier-grade networks.

Real-time Industrial Ethernet (RE), especially IEC 61158, plays increasing role in industrial communications these days, so our motto is to concentrate on Energy efficiency of interest for industrial communications. The alteration introduces a new operational mode, well-defined as Low Power Idle (LPI) that permits to noticeably reduce the power consumption of inactive Ethernet links. We flinch with an explanation of the EEE basics and, afterward, emphasis on the overview of EEE in the industrial communication scenario. Then, we explicitly address the carrying out of effective EEE strategies for some widespread RTE networks.
