Abstract
Energy consumption of the telecommunication networks contributes to a large portion of the greenhouse gas (GHG) emissions due to the global electricity consumption. Furthermore, backbone networks dominate the energy consumption of the telecommunication networks by high peak data rates. In this paper, we enhance our previously proposed energy-efficient availability design scheme for IP over WDM (IP/WDM) networks, i.e., Power-Aware Reliable Design (PARD).1 Here, PARD-QoP is proposed which incorporates Quality of Protection (QoP) with power-aware reliable IP/WDM Network design. According to the QoP concept, each connection demand specifies a working bandwidth capacity requirement and a minimum backup capacity requirement. We evaluate the performance of PARD-QoP under the 14-node NSFNET topology for six QoP classes that are uniformly distributed among the connection requests and for various demand sizes. The simulation results show that PARD-QoP enhances its predecessor PARD by 7%-12% in terms of Capital Expenditure (CAPEX), denoting the number of wavelength channels, and by 4%-8% in terms of Operational Expenditure (OPEX), denoting the energy consumption. Moreover, PARD-QoP is shown to differentiate the demands in three availability classes as 99.9%, 99.99% and 99.999% with respect to the backup bandwidth requirements.
