An optical circuit switching network architecture and reconfiguration schemes for datacenter

The paper presents an optical circuit switching network architecture and its control and traffic scheduling schemes. This optical switch network is built on a 32×32 AWG and fast wavelength tunable transmitters and is able to support up to 128 interface ports. The feasibility of the architecture is verified through an experimental study. The traffic scheduling scheme takes into account the transmitter wavelength tuning time so as to avoid frequent connection reconfiguration. The simulation results show that fast connection reconfiguration speed and efficient traffic scheduling scheme enable optical circuit switching network to deliver high transmission bandwidth and low packet delay performance in datacenter network.
