Wavelength conversion and wavelength assignment are key determinants of the blocking performance of wavelength-routing WDM networks. In this paper, we investigate the relative performance advantage offered by wavelength converter placement and wavelength assignment. A heuristic for conversion placement that considers constraints imposed by four different converter node architectures is proposed. Also, two heuristics for wavelength assignment are proposed, and the performance is evaluated through simulations. Results indicate that the shareper-link architecture provides a good balance between cost and performance, and that wavelength assignment algorithms are more important than converter placement algorithms in determining the blocking performance.
