Patent ID: 8355633

Claim:
A communication network management system provided with two or more node apparatuses which transmits an optical wave for different wavelengths and a communication management apparatus which sets prescribed path setting data for each of said node apparatuses for forming a transmission path for said optical wave; wherein each node apparatus comprises: a wavelength detecting part which detects the wavelength of an optical wave which is transmitted through a transmission path formed such that it includes the node apparatus, and wherein said wavelength detecting part detects an output wavelength and an input wavelength of an optical wave transmitted through a transmission path formed such that it includes the node apparatus; a destination node detecting part which detects a node apparatus connected to said transmission path; a connection information storage part which stores prescribed connection information indicating said wavelength and said node apparatus, and wherein said connection information storage part stores prescribed connection information indicating said output wavelength, said input wavelength and said apparatus connected to said transmission path; a connection information sending part which sends said connection information to said communication management apparatus; and a path setting part which sets a transmission path based on path setting data received from said communication management apparatus, said communication management apparatus comprises: a connection information receiving part which receives said connection information from each node apparatus; a path setting data generating part which generates predetermined path setting data relating to a node apparatus based on said received connection information; and a path setting data sending part which sends said generated path setting data to said node apparatus.
