This paper proposes an energy efficient multi-layer network using extended GMPLS with link power control. The experimental result shows that dynamic energy saving according to traffic volume is realized by layer-1 and layer-2 unified control.
We develop a P2MP energy-saving routing design using Prim's algorithm to reduce the energy consumption of the transport network for multipoint services. By computer simulation, it is shown the developed algorithm provides an energy-saving topology within 1 second and reduces number of links up to 57% in 40 node network.
We have studied a novel optical access network with PLZT (Plomb Lanthanum Zirconate Titanate) optical switches, called ActiON (Active Optical Network), as a next generation access network to replace PON (Passive Optical Network). On the other hand, energy consumption of the present network becomes an important problem today. To resolve this problem, we study an energy efficient metro-access hybrid...
In order to reduce the energy consumption of the network, we introduce a concept that realizes a low power consumption network by aggregating traffic on specific numbers of links and powering off link ports of routers that are not used. In this paper, we proposed a practical calculation method that can derive a low power consumption network considering QoS requirements. By iterating the process of...
