“…In essence, the former one is called sleeping mode while the latter one is known as rate switch. Operating systems and application may be utilized to contribute to energy conservation [18][19][20][21][22][23][24][25][26][27]. On the other hand, rate switching seems a more straightforward task because an option of the existing link features will be selected, for example, 10 Mbps or 100 Mbps or 1000 Mbps for a typical Ethernet link; however, its performance is lower that the function of the sleeping method.…”

“…The NIC remains in sleeping mode while light traffic processing, for example, Address Resolution Protocol answers, is only required. Recent studies in incorporating sophisticated TCP algorithms to reduce the energy consumption mobile devices [21], improving the user goodput in wireless networks without increasing the available bandwidth using cognitive TCP techniques [22], exploiting the knowledge of perceiving how the sleep interval length can influence TCP throughput in a passive optical network [23], and applying efficient TCP-based buffering techniques in cloud environment [24] reveal the need of devising novel, rigorous, and efficient energy-efficient techniques in a variety of research fields. On the other hand, an external proxy handles light control traffic requests.…”

“…In other words, such schemes apply device coordination in one or multiple levels in order to exchange useful control information and therefore extend the applied sleeping periods. Operating systems and application may be utilized to contribute to energy conservation [18][19][20][21][22][23][24][25][26][27]. A survey of possible energy-efficient techniques for implementing in network elements were presented in [18].…”

Power management has emerged as a challenge of paramount importance having strong social and financial impact in the community. The rapid growth of information and communication technologies made backbone networks a serious energy consumer. Concurrently, backbone networking is deemed as one of the most promising areas to apply energy efficient frameworks. One of the most popular energy efficient techniques, in the context of backbone networks, is to intentionally switch off nodes and links that are monitored underutilized. Having in mind that optical technology has thoroughly dominated modern backbone networks, the function of switching off techniques entails fast operation and rigorous decision-making because of the tremendous speed of the underlying optical media. This paper addresses this challenge by introducing a novel, adaptive, and efficient power management scheme for large-scale backbone networks. The proposed framework exploits traffic patterns and dynamics in order to effectively switch off the set of network entities in a periodic fashion. An adaptive decision-making algorithm is presented to maximize the network energy gains with respect to time constraints as well as QoS guarantees. The conducted simulation results reveal considerable improvements when applying the proposed framework compared with other inflexible energy efficient schemes. of 26rapid advancement of ICT networks should be accompanied with energy efficient frameworks and paradigms.Backbone networks constitutes the foundation of ICT. They connect end users together by providing access to multitude services such as voice, video, file transfer, and messaging. During the last decade, we have been witnesses of the massive penetration of optical networking in backbone infrastructure. Optical fiber offers huge capacity, scalability, reliability, and cost-effective access solution (e.g., fiber to the home). Undoubtedly, optical technology architectures established an end-game approach; hence, the question is transformed on how optical networking solutions could contribute towards energy conservation.Both academia and industry are in harness with in order to devise effective research solutions regarding energy reduction in optical backbone networks. According to [2], there are four main directions on minimizing energy consumption in ICT networks, which are as follows: (i) development of new environmental-friendly network components; (ii) re-defining physical characteristics regarding the signal transmission and reception; (iii) advancements in application layer; and (iv) allocating network resources in a more efficient way subject to energy consumption. The development of energy efficient components is a feasible task, however the progress of such development is slow. Low-attenuation and low-dispersion fibers are only a few examples of developing energyaware solutions in the physical layer. Even though such a solution is quite interesting, it might increase the transceiver cost and therefore the cost of the whole installation. Improvements in ...
