 note = {We investigate the relation between waveband add/drop ratio and switch size for hierarchical  optical path cross-connects. We then propose a design algorithm for hierarchical optical path  networks that considers restrictions on the waveband add/drop ratio. Its performance is  evaluated by numerical experiments.},
