Báo Cáo Wavelength conversion in wdm network

Wavelength conversion in wdm networkFor the purpose of using network resources effectively, that is, minimizing congestion in optical WDM
networks, routing and wavelength assignment algorithms, wavelength conversion methods are
discussed here. Wavelength conversion has been shown as one of the key techniques to improve
blocking performance in a wavelength-routed all-optical network. Given that wavelength converters
nowadays remain very expensive, how to make effective use of a limited number of wavelength
converters becomes an important issue.In this paper, we propose a novel sparse-partial wavelength
conversion (SPWC) architecture with the inherent flexibility that can facilitate network carriers to
migrate the optical backbone to support wavelength conversion. We demonstrate that this architecture
can significantly save the number of wavelength converters while still achieving excellent blocking
performance.
