1. A method comprising:
obtaining, by a controller of an optical network, input parameters that include a generalized signal-to-noise ratio (GSNR) for optical signals and an allocated bandwidth of an optical link in the optical network;
obtaining, by the controller, for a combination of at least one line rate and at least two baud rates, a mapping of a plurality of traffic modes along a frequency spectrum of the allocated bandwidth compatible with the GSNR;
generating, by the controller, a channel plan in which a number of selected traffic modes from the plurality of traffic modes and a distribution of a plurality of channels in the allocated bandwidth are set to maximize transmission capacity of the optical link, wherein the plurality of channels is used for transmitting the optical signals on the optical link; and
configuring, by the controller, at least one couple of optical network elements in the optical network, to establish the optical link based on the channel plan.
