摘要：A method for constructing an optical network includes connecting each of aplurality of nodes in an optical network to an optical switching central node via a set ofoptical superchannels, wherein each of the optical superchannels includes of a set ofsubchannels and has a bounded data rate, and wherein the optical switching central nodeis configured to perform wavelength selective optical switching among the superchannelson a subchannel basis without spectrum contention. Moreover, rearrangement (or“permutation”) of the subchannels of the superchannels connected to the n sites maybe performed to minimize the total spectral bandwidth used by the superchannels.
