METHOD FOR DETERMINING ROUTE AND WAVELENGTH OF OPTICAL PATH OF WAVELENGTH MULTIPLEXING NETWORK, RECORDING MEDIUM WITH PROGRAM FOR EXECUTING THE DETERMINING METHOD RECORDED THEREIN, AND WAVELENGTH MULTIPLEXING NETWORK CONFIGURED BY THE DETERMINING METHOD

摘要

PROBLEM TO BE SOLVED: To determine the routes and the wavelengths of optical paths in a wavelength multiplexing network so that the number of optical cross-connecting devices having respectively wavelength converting functions is reduced to a minimum.;SOLUTION: In the determining method, with respect to all optical paths, whether each of all the optical paths which includes a node Nn (n is an integer of 1-N) neither as a starting point nor as a terminating point performs a wavelength conversion at the node Nn or not is decided. Then, when all the optical paths perform to wavelength conversion at the node Nn, a numeric value Wn is recorded as 0, and when at least one of all the optical paths perform the wavelength conversions at the node Nn, the numeric value Wn is recorded as 1. Subsequently, the routes of all the optical paths and the wavelengths of all the optical paths each of which is assigned to each optical fiber transmission line included in each optical path are selected with respect to all nodes N1, N2,..., NN so that the sum of the recorded N numeric values W1, W2,..., WN is minimized.;COPYRIGHT: (C)2002,JPO
