Analysis of least congested path routing in WDM lightwave networks

Abstract
Analyzes an adaptive routing rule in a WDM lightwave network. Each switching node in the network may have a number of wavelength converters which can be used to resolve wavelength conflicts in multi-hop paths. The authors found that without any wavelength converters, the wavelength conflict possesses an inherent blocking to alternate route traffic and that the use of wavelength converter to resolve wavelength conflicts does not give any significant reduction of blocking probability
