Although the design issue of networks with full waveband/wavelength conversion is free from the waveband/wavelength assignment, the cost minimization is hard to solve due to the degree of freedom in determination of waveband path location. Thus we firstly divide the original problem into sequential two-stage integer linear programming formulations that respectively concentrate on wavelength/waveband path accommodation. Numerical experiments elucidate that, without considering the cost of converters, the proposed algorithm achieves up to 30% cost reduction compared with a conventional algorithm without wavelength conversion [Yagyu, et al., 08]. Over a broad range of traffic demand, hierarchical optical path networks designed by the proposed algorithm achieves lower cost than single layer optical path networks where existing algorithms failed to realize the cost reduction.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_10_description_5": {"attribute_name": "内容記述", "attribute_value_mlt":
