In this paper, we investigate the energy-efficient grooming with distance-adaptive load balancing (EEG-DALB) in flexible bandwidth optical networks. For comparison, an existing energy-efficient approach without grooming and load balancing (EEA-WGLB) is also introduced. Simulation results show that the proposed EEG-DALB achieves better performance in terms of the blocking probability and average power...
Due to the accelerated evolution of application services, optical network virtualization simplifies optical-layer resource management and provides flexibility in spectrum resource allocation. However, the energy consumption is one of the great challenges in the virtual optical networks (VONs). This paper focuses on the energy efficiency problem in survivable VONs with the sliceable multi-flow transponders...
