Dynamic wavelength allocation technique with multicast-capable AWG router for energy-efficient intra-datacenter networks

Large-scale N × N arrayed waveguide grating (AWG) routers can be applied to optical intra-datacenter networks. This paper proposes an energy-efficient dynamic wavelength allocation (DWA) technique using a multicast-capable AWG router for optical intra-datacenter networks. Simulation results show power-saving performance of the proposed technique.
