PROBLEM TO BE SOLVED: To surely and effectively set a full-mesh path just by using the least number of wavelengths among plural nodes. SOLUTION: First to N-th numbers are given in order of connection to the nodes S1 to SN, which configure a system, and (N2-1)/8 pieces of wavelength paths, having the number of hops smaller than (N-1)/2 hops are set to each of half of nodes S1 to S(N-1)/2. Then the wavelength of a wavelength path that is used for inserting an optical signal from each of nodes of numbers (N+1)/2 to N, equivalent to the other half of the system are set to these nodes by allocating again the wavelength of each hop wavelength path that reaches each of these nodes. Furthermore, an unset signal inserting wavelength path is set to each of nodes having numbers 1 to (N-3)/2 by allocating again the wavelengths of wavelength paths reaching these nodes. |
