Abstract

The network resource utilization efficiency is limited by the rigid nature of the current wavelength-routed optical networks. The recently proposed flexible optical network can allocate the spectral resources adaptively according to the traffic demand. Meanwhile, the transmission quality has always been a main objective during the routing process in optical networks. Recently, the energy efficiency has also been a hot topic because of the energy consumption problem. In this paper, we propose a novel weighted energy efficient routing and spectrum assignment scheme based on the designed quality of transmission (QoT)-energy estimation model in which the physical impairments and energy consumption are given consideration to two or more things. The simulation results demonstrate that the proposed algorithm can make a better balance between the quality of service (QoS) and energy efficiency.
