Demonstration of the Self Organized Dynamic Link Power Management by “MiDORi” Energy Optimal Network Topology Design Engine

Application-Centric, Energy-Efficient Network Architecture ACTION, Based on Virtual Optical Slice Core and Deterministic Optical Access Network

“…In order to reduce power consumption in the physical network, this core network introduces the MiDORi [8][9][10][11][12][13] technique. The MiDORi aggregates multiple traffic flows onto a small number of physical routes, creating highly utilized links wherever possible, and instructs the router to power-off unused interfaces whenever possible, as shown in Fig.…”

“…The virtual optical slice core network can guarantee multi Quality of Services (QoS) by adjusting elastic optical pipe bandwidth and can provide an energy efficient network by adopting the Multi-(layer, path, and resources) Dynamically Optimized Routing (MiDORi) technique [8][9][10][11][12][13], which aggregates traffic onto a small number of links and powers off the routers that are not used to convey traffic. Also, the edge nodes of the core network, called ACTION edges, monitor application Quality of Experience (QoE) and assign flows to various multi-QoS slices.…”

A study on network control method in Elastic Lambda Aggregation Network (EλAN)

“…L-ONU #3 already proposed in the core network area [9] and the access network area [10]. However, in the case of EλAN, L-OLTs have to migrate between P-OLTs to continue providing the same network services.…”

“…5) After migrating all L-OLTs from P-OLT(#2), the management server instructs P-OLT(#2) to go to sleep mode. In the real network environment, the amount of traffic varies with the time of day [9]. It is preferable to change the number of operating P-OLTs along with the hourly fluctuation of the traffic amount to avoid unnecessary L-OLT migrations and ODN reconfigurations.…”

Método para avaliação de sistema de gerenciamento de redes orientado a eficiência energética.

“…Considerações finais do conteúdo deste capítulo são apresentadas na Seção 3.10. (Chabarek, 2008), (Gupta, 2003) e (Heller, 2010 (Chaudhari, 2012), (Zhang, 2010), (Takeshita, 2011 (Chandramouli, 2011). Tal modelo prevê a existência, entre os estados ativo e inativo de um equipamento, de vários modos intermediários para redução do consumo de energia.…”
