Abstract
An optical network system includes a master node and a plurality of optical switch nodes, allowing the number of nodes without depending on the number of wavelengths. The master node is configured to: divide a wavelength path having an arbitrary wavelength into time slots each having a predetermined time period; and allocate the time slots to each of the optical switch nodes. Each of the optical switch nodes is configured to: synchronize the time slots based on information delivered from the master node; and thereby transmit or receive a data or performs route switching.
