METHOD FOR SETTING OPTICAL WAVELENGTH PATH

摘要

PROBLEM TO BE SOLVED: To attain efficient wavelength selection such as the same wavelength without the need for wavelength conversion over all paths by means of signaling.

SOLUTION: In the optical wavelength path setting method where in the case of connecting a plurality of links subjected to wavelength multiplexing to nodes configuring an optical communication network, signaling is used to make reservation of an operating wavelength from an outgoing node to an incoming node, all the wavelengths are divided into a plurality of blocks and one of the blocks is used in the signaling to display an idle state of the wavelengths by means of a bit map.
