Abstract

We present a hierarchical algorithm for grooming lightpaths into wavebands, and routing wavebands over a network of multigranular switching nodes. This algorithm focuses on lowering the number of wavelengths $W$ and ports over the network while being conceptually simple, scalable, and consistent with the way networks are operated and controlled in practice. Our experiments indicate that this algorithm easily scales across different waveband and network sizes.

Keywords: Multigranular optical networks Hierarchical grooming Waveband switching
