摘要

Current as well as future IoT networks enabled applications and services are characterized by bandwidth intensiveness and as such are directly driving the need for optical backbone networks as they o provide the required high bandwidth capacity demands. Dense wavelength division multiplexing (DWDM) technology coupled with optical burst switching (OBS) are promising candidate technologies towards the provisioning of the necessary capacity transmission as well as switching supporting capability for such backbone networks. Since infrastructural hardware equipment requirements are trebling every two years because of continued surging bandwidth demands, the industry is also a growing direct contributor to worldwide greenhouse gases (GHG) emissions as well as energy consumption. As a result, it is necessary to research on more energy efficient ways to design and operate these networking infrastructures. A novel optimized energy-aware lightpath routing (OEA-LR) proposal is proposed that is utilized to study the effects of energy optimization on pertinent network performance metrics. It takes into account the effects of physical layer impairments (PLI) since their effects in high speed networks may not be ignored when formulating routing and wavelength assignment (RWA) algorithms. In our proposal, we assume that a translucent DWDM optical backbone network that incorporates optical cross-connects (OXCs), Erbium Doped Fiber Amplifiers (EDFAs), transceivers, and various fiber link lengths. We further assume that connection requests from source to destination are entirely provisioned in the all-optical domain, thus optical to-electronic to-optical (OEOs) conversions are not present. Obtained results from the simulations show that the approach does improve both energy efficiency as well as resources utilization. We further observe a general reciprocation between energy savings versus blocking performance.
