Chen L., Modiano E. Efficient Routing and Wavelength Assignment for Reconfigurable WDM Ring Networks With Wavelength Converters

IEEE/ACM TRANSACTIONS ON NETWORKING, VOL. 13, NO. 1, FEBRUARY 2005.
We consider the problem of wavelength assignment in reconfigurable WDM networks with wavelength converters. We then provide a second algorithm that uses more wavelengths yet requires significantly fewer converters. We also develop a method that allows the wavelength converters to be arbitrarily located at any node in the ring. This gives significant flexibility in the design of the networks.
