“…e-science applications), and the energy consumption of optical networks is becoming an important issue. Bathula and Elmirghani [Bathula and Elmirghani 2009b] proposed a model expressing the energy required to transmit an optical bit across a Wavelength Routed Node (WRN). They assume that an optical network consumes energy in two cases: when transmitting a bit over fiber and when a WRN switches an optical signal.…”

The great amounts of energy consumed by large-scale computing and network systems, such as data centers and supercomputers, have been a major source of concern in a society increasingly reliant on information technology. Trying to tackle this issue, the research community and industry have proposed a myriad of techniques to curb the energy consumed by IT systems. This article surveys techniques and solutions that aim to improve the energy efficiency of computing and network resources. It discusses methods to evaluate and model the energy consumed by these resources, and describes techniques that operate at a distributed system level, trying to improve aspects such as resource allocation, scheduling and network traffic management.This work aims to review the state of the art on energy efficiency and to foster research on schemes to make network and computing resources more efficient.

ABSTRATCTSince its emergence the internet has been a significant part of today's modern living. Defined by its interconnections and routing policies, it has fuelled increased demands for provisioning of new more advanced services that are able to dynamically react to changes within the network. These services however, lead to enormous energy consumption in contrast to a global drive for a greener environment. Hence the existence of an optical infrastructure that complies with the principles of zero-carbon emission is imperative.Subsequently, in this paper, we present an energy model of Generalized Multi-Protocol Label Switching (GMPLS) network for more power efficient Green Photonic Networks. We are proposing a greener network design based on a novel routing algorithm to deliver power reduction through implementation of so called "Hibernation" approach. The scheme includes network topology such as group the nodes configuration, segmentation of the link/ports, and wavelength provisioning via partitioning. The performance evaluations of these energy saving schemes are investigated by including various challenging issue on "greening the internet" and reduces carbon footprint. In addition, to study the impact of wavelength request, blocking probability and power consumption in relation to network load is taken into account. A trade-off is observed between energy per bit, wavelengths offered (Erlang) and blocking probability as a result of the idling nodes.

Abstract-Recent developments in Optical IP networks have heightened the need for reduction on power consumption via so called green photonics and concepts known as green networking. Adhering to these principles we proposed a novel energy savings approach which can be applied to optical IP networks and is based on so called "hibernation mode with segmentation link" technique. The hibernation mode technique is designed to help to reduce power consumption by sleep the network links and can help to optimise network overall energy usage by taking advantage of the hibernation algorithms we have developed. The proper implementation over the network infrastructure will save energy, operating cost to network operators, and while at the same time will also deliver reduced carbon footprint. In this paper, we show design model for developing energy efficient Segment-Link approach. In this scheme, the improvised energy saving techniques focus on selective sleeping of optical core fibre links, following which the Routing Wavelength Assignment algorithm based on GMPLS control plane are investigated. Simulation models and results for the proposed scheme are evaluated in both the fibre link only and segmentation-link schemes scenarios. The results shows that a significant amount of energy can be saved if appropriate "segmentation-link" mechanisms using optical bypass and traffic grooming is invoked. 
