摘要：In this article, an efficient heuristic approach for routing and wavelength-selective(RWS) in wavelength-division multiplexing (WDM) optical networks is proposed. The high bandwidth of fiber-optic links is utilized through the WDM technology which supports the propagation of multiple laser beams through a single fiber-optic link provided that each laser beam uses a distinct optical wavelength. Thus, optical communication introduces a new routing environment with new characteristics different from traditional one. Wavelength converters are used to effectively alleviate the blocking probability and help to resolve contention at the output port of switches by shifting one incoming wavelength to another outgoing wavelength at an oxe node. With the help of wavelength converters, the WDM optical network will utilize the wavelength resources efficiently. ?2010 IEEE.
