Abstract:
Electricity costs comprise a significant portion of operating expenses forData Center Networks (DCNs). As a result, energy-aware Routing and Wavelength Assignment schemes (RWA), which try to minimize the overall energy consumption for data transmission, have received considerable attention in the past decade. Recently, the idea of minimizing the dollar cost of energy consumption using Real-Time Pricing (RTP) has been proposed for Wavelength-Division Multiplexing (WDM) optical networks. The RTP-based RWA has been shown to result in reduced electricity costs. In this paper, we present a new formulation for optimal RWA for scheduled lightpath demands using the RTP model. Our results indicate that the proposed approach clearly outperforms the Flat-Rate Price (FRP) model, as well as traditional shortest path routing schemes.
