Abstract
A network includes a plurality of interconnected nodes utilizing an all-broadcast architecture for a plurality of wavelengths therebetween; a routing protocol configured to compute a loop-free path through the plurality of interconnected nodes, wherein the loop-free path is computed for at least one wavelength of the plurality of wavelengths using routing constructs adapted to a photonic domain; and at least one blocking element configured to selectively block the at least one wavelength based on the computed loop-free path. A routing method photonic node are also disclosed.
