Abstract :
Impairment-Aware Routing and Wavelength Assignment (IA-RWA) is essential for optical network due to accumulated impairments which may degrade signal quality. Wavelength converter can release the wavelength continuity constraint, so considering the presence of wavelength conversion in IA-RWA algorithm can improve the network resource utilization. In this paper we propose a multi-domain IA-RWA algorithm with wavelength conversion. Simulation results show the algorithm can achieve good performance in blocking probability.
