Paper Abstract

In this paper, we investigate the wavelength assignment issue in wavelength-routed all-optical WDM networks with Sparse-Partial Wavelength Conversion. Traditionally, wavelength assignment is only designed for the purpose of decreasing the blocking probability. In Sparse-Partial Wavelength Conversion, wavelength assignment can be used to decrease the number of wavelength converters if keeping the same level of blocking probability. We propose three different wavelength assignment algorithms, namely Segment-First First Fit (SFFF), Path-First First-Fit (PFFF), and Minimum Converter Allocation (MCA). Our results show that MCA is the best one among the three, and it can achieve very close performance to Sparse Wavelength Conversion by using a very small number of wavelength converters. The performance of PFFF is very close to MCA, and it is very simple to be implemented.
