hello all, I have a question. I would like to know what algorithm is recommended for path computation across WDM network by a PCE. Will it be a modified version of dijkstra - with one run to check for optical constraints at every hop included into the SPF tree and find shortest path by metric , or the K-th shortest path algorithm to continuously explore many paths and check optical constraints( such as wavelength continuity, ROADM directionality constraint etc) on each of the paths one by one
