Wavelength Conversion in Shortest-Path All-Optical Networks

by Thomas Erlebach, Stamatis Stefanakos , 2003
"... We consider all-optical networks with shortest-path routing that use wavelength-division multiplexing and employ wavelength conversion at specific nodes in order to maximize their capacity usage. We present efficient algorithms for deciding whether a placement of wavelength converters allows the net ..."

Routing and Wavelength Assignment in All-Optical Networks with Multicast Traffic

by Yong Sun, Jun Gu, Danny H.K. Tsang
"... In this paper, we consider the Routing and Wavelength Assignment (RWA) problem in all-optical wavelength-routing networks with multicast traffic. The RWA problem has been proved NP -hard. Many researchers are working on this problem and many algorithms have been proposed to solve the RWA problem. ..."

Cross-Layer Adaptive Routing and Wavelength Assignment in All-Optical Networks

by Yvan Pointurier, Suresh Subramaniam, Bo Xu
"... Abstract — In WDM all-optical networks where electrical re-generation is not available, physical impairments due to propaga-tion in the fibers, amplifier noise, and leaks between channels and in the switches cannot be removed at the physical layer. These effects cause calls, especially between physi ..."
