“…Combining technological efficiency measures with pollution capping would "create incentives that would spur demandside efficiencies to match those already realized on the supply side" (ibid.). Besides, policies and strategies could be developed to support energy-aware ICT by design, as suggested by Ricciardi et al for the Internet [67]. This would enable ICT to control for their energy impacts from the design stage, in a similar fashion to what has been done with "privacy-by-design" technologies [68].…”

“…Both the above concepts have to be considered in modern energy-oriented RWA paradigms encompassing renewable energy sources and energy efficient devices in a systemic approach that spans the whole life-cycle assessment of the next generation networks. Accordingly, in [12,13] the reduction of both energy costs and GHG emission through use of renewable energy sources has been investigated. To achieve the needed optimizations new routing algorithms are envisioned, taking into consideration the availability of low-power or energy-proportional operating modes [14] as well as the type of power feed given to the wavelength switches (green, dirty), according to the information provided by the Smart electric grids [15].…”

“…It is worthwhile to note that the power consumption of idle routers is always present since we assume that no sleep mode is available at router level, i.e. an idle router cannot be put into sleep mode, as reported also in [13,27]. Therefore, any energy-related optimization relies on the variable power consumption of routers, selecting short routes passing through routers with low energy scaling factors.…”

In the last years, the power consumption of telecommunication networks has attracted the attention of both researchers and field experts in order to contain the associated energy bills and reduce their ecological impact. Many of the proposed solutions have been focused exclusively on the reduction of the power consumption, without adequately considering more traditional network engineering objectives such as balancing resource utilization, routing policy, or resilience schemes. As a consequence, network control plane strategies passed from one extreme to the other, from being totally energy-unaware to exclusively energy-efficient at the expenses of load-balancing, with obvious impacts on the power consumption in the former case and on the blocking rate in the latter one.\ud \ud In this paper, we present a hybrid routing and wavelength assignment algorithm that, when the network is lightly loaded, operates in an energy-efficient way, by routing the connections on the paths requiring the lowest amount of energy, while, when the network load increases, it dynamically switches to a pure load-balancing scheme in order to best allocate the available communication resources. The switching decision among load-balancing and energy-awareness is taken dynamically, driven by a threshold on the number of new connections requests reaching the network during a prefixed time window.\ud \ud Simulation results show the effectiveness of the hybrid algorithm, which achieves lower energy consumption than a pure load-balancing algorithm while keeping the network load fairly distributed on the available resources.Peer ReviewedPostprint (author's final draft

“…The model is based on a dual optimization problem, where the objectives are quality of service and energy or temperature minimization. In [15] the authors have proposed the introduction of energyawareness into control plane protocols whose goal is to properly condition all the route/light path selection mechanisms on relatively coarse time scales by privileging the use of renewable energy sources and ether efficient links/switching devices. By combining, the notable features that a comprehensive energy aware network model should have and put them into a constrained routing and wavelength assignment problem framework.…”

As part of the energy efficient system modeling, which is of interest amongst all areas of research in industry and academia, this paper proposes a design of energy efficient Ethernet access system. The model estimates the feasibility of operating the network interface component under power saving modes, without compromising on the quality of service. In order to prevent degradation of the service quality, the constraint ensures that the estimated duration of sleep time does not go beyond a certain threshold parameter, or maximum allowable delay limit per packet processed, within a given flow. The allowable limit or threshold value of the delay is fixed across each flow and corresponds to its priority tag, where a higher priority means, lower allowable delay. Simulations have been carried out for the algorithm and graphs plotted, to validate the feasibility of the proposed model.
