A communication system includes a plulrality of nodes, a data signal line and a control signal line. The plurality of nodes are coupled each other through the data signal line so as to perform communication by using a signal multiplexed by at least one of a wavelength-division multiplexing scheme and a time-division multiplexing scheme. The plurality of nodes are coupled each other through the control signal line by which a control signal including a management table indicative of at lease one of a time slot and a wavelength of a signal used for communication in the data signal line is circulated. Each node inputs a control signal circulating through the control signal line to select at least one of a time slot and a wavelength of a signal not used for communication on the basis of the management table of the input control signal, so that the communication is performed through the data signal line by using at least selected one of the time slot and the wavelength of the signal and the management table is updated to be outputted to the control signal line. <IMAGE> <IMAGE> |
