Abstract:
A method implemented in an optical flexible wavelength division multiplexing FWDM network includes finding a first channel out of available channels with sufficient spectrum on a given route out of available channels in an optical FWDM network; finding a second channel at a lower wavelength out of the available channels for minimizing total spectrum on the given route; selecting a channel out of the available channels on K-distinct shortest routes; and finding line rates of channels using a predetermined channel selection.
