Claim One:
1. A method for optimizing an optical network, comprising: obtaining a lightpath demand set including a plurality of lightpath demands; generating a plurality of lightpath demand sequences with different orders from the lightpath demand set; obtaining results of respective lightpath demand sequences in parallel by a plurality of processing terminals in heuristic algorithm; and obtaining all the results, and comparing the results to obtain an optimum result, wherein the obtaining the results of the respective lightpath demand sequences in heuristic algorithm comprises: scanning waveplanes for each lightpath demand to determine whether there is a waveplane configured to accommodate the lightpath demand; in a case that there is the waveplane configured to accommodate a lightpath demand request, establishing a connection by the waveplane determined at the first time; in the case that there is no waveplane configured to accommodate the lightpath demand request, adding a new waveplane to accommodate the lightpath demand; and after all the lightpath demands are accommodated, counting a total number of waveplanes to obtain a number of waveplanes to be expected.
