BRANCH INSERTION DEVICE, NETWORK SYSTEM, TRANSMISSION METHOD, NON-TRANSITORY COMPUTER-READABLE MEDIUM, AND MANAGEMENT DEVICE

摘要

The objective of the present invention is to provide a wavelength path communication node device capable of outputting an arbitrarily defined wavelength and capable of outputting to an arbitrarily defined route, and with which wavelength/route collisions do not occur. This branch insertion device (11) is provided with: a communication unit (101) which communicates an optical signal to at least one client device and at least one network; and a control unit (102) which indicates to the communication unit (101) a transfer destination for the optical signal in accordance with attributes of the received optical signal. The control unit (102) indicates to the communication unit (101) an amount of attenuation of the optical signal for each device to be connected, and if the device to be connected changes, indicates to the communication unit (101) a change in the amount of attenuation. The communication unit (101) attenuates the optical signal by the amount of attenuation indicated by the control unit (102), and transfers the attenuated optical signal to the transfer destination.
