Abstract
We analyze cost reductions possible with the introduction of a waveband converter
or both wavelength and waveband converters to hierarchical optical path
networks. We propose network design algorithms that are based on multistage
integer linear programming (ILP) or heuristics. Numerical experiments prove that
by employing waveband converters or both waveband and wavelength converters,
hierarchical optical path networks can be cost effective over wide traffic
demand ranges and a broad converter cost range.
