AO Fa-liang, HU Han wu. Layered-graph algorithm of static routing and wavelength assignment for optical networks[J]. 2003,(3):1-3. DOI: 10.13756/j.gtxyj.2003.03.001.
This paper puts forward a heuristic algorithm of routing and wavelength assignment (RWA)
which unifies the routing and wavelength assignment subproblems.Through a new layer graph (LG) algorithm and limitative coefficient k
the routing and wavelength assignment of all optical networks can be optimized
so the wavelength number required for setting up optical connects can be minimized. Finally the performance was studied for five realistic optical networks
including the ARPANet.It proves that this LG algorithm performs better than the existing ones.
