Optimization of the Placement of Wavelength Converters in WDM Networks

摘要

The Routing and Wavelength Conversion are the two key techniques for improvement of the overall blocking performance in the wavelength routed all-optical networks. The Wavelength Converters are expensive, and thus the effective use of Wavelength Converters or more precisely the placement of minimum number of Wavelength Converter in appropriate nodes in the network is a challenge in the field of wavelength division multiplexing (WDM) optical networks. The performance of wavelength division multiplexing (WDM) network is highly dependent on Wavelength Converter allocation and routing problems. Typically treated as independent problems under dynamic traffic.
