Nowadays energy efficiency has been one of the most urgent issues for Data center networks. Flow scheduling methods based on exclusive routing have been used to minimize the network energy while meeting the network performances, such as network throughput, and flow deadline. However these energy efficient exclusive routings only maximize the utilization of ports, which may leave switches underutilized...
This paper proposes a methodology for resource consolidation towards minimizing the power consumption in a large network, with a substantial resource overprovisioning. The focus is on the operation of the core MPLS networks. The proposed approach is based on a software defined networking (SDN) scheme with a reconfigurable centralized controller, which turns off certain network elements. The methodology...
