Abstract

In a wavelength-routed WDM network, a lightpath must be established between a pair of source and destination nodes before data can be transferred. Due to the limitation in the number of wavelengths on each fiber link, efficient use of the wavelength resources is crucial for achieving good network performance, especially in the absence of wavelength conversion. While a good routing and wavelength assignment (RWA) algorithm [1] is critically important in improving the network performance, wavelength rerouting offers another effective way that can also increase the wavelength utilization and thereby improve the network performance in terms of the connection blocking probability.
