Experimental Evaluation of Server Centric Passive Optical Network Based Data Centre Architecture

“…In recent years, higher data rates and power efficiency in data centres have become essential, hence several studies have been carried out in optimising energy efficiency and architectures in data centres and the core networks connecting them [1]- [10]. In order to validate the results of these studies, experimental work was needed to deploy and evaluate these architectures.…”

Bounds on GreenTouch GreenMeter Network Energy Efficiency

“…In the white papers in [1], [2], the Greentouch consortium published the results of a thorough study on implementing a set of technologies and solution for an end-to-end energy reduction in mobile access, fixed access and core networks and is referred to as the GreenMeter. The core networks category considered multiple layer solutions and the results are summarized in [3] combining the individual solutions. The solutions include the bypass approach, the mixed line rates, physical network topology optimization, the optimization of distributed clouds for content distribution, and virtualization of network equipment.…”

“…In [3] we produced a collective mixed integer linear programming optimization model incorporating the mentioned energy efficiency schemes, and evaluated the collective mixed integer linear programming (MILP) model over the AT&T topology. In this paper we extend our work by developing bounds on the power consumption of core networks for the non-bypass, bypass, mixed line rate and topology optimization scenarios to verify the energy savings of these schemes individually obtained through MILP optimization models and to provide simple analytic bounds and closed form expressions that can be used to obtain results for individual measures or a set of measures.…”

Real-Time Emissions of Telecom Core Networks

“…In the present research, we focus on estimating the energy consumption of IP over WDM core networks as they provide a high network bandwidth for the Internet backbone, transporting traffic. In the literature, several papers have a focus on minimizing the energy consumption of IP over WDM networks considering multiple dimensions [4]- [15].…”
