Abstract

Abstract

With XGM (Cross-Gain Modulation) technology, a type of all-optical wavelength converter can be simply made. In this paper, using a simple model, the influence of path blocking probability made by XGM wavelength converter is first analyzed, then considering the characteristic of XGM wavelength converter, three kinds of RWA(routing and wavelength assignment) are designed, which are suitable for the all-optical XGM wavelength converters. By simulating in NSFNET and Mesh-torus network, the performance improvement is assessed and the performance of the three kinds of RWA are compared. The simulation results show that significant improvement in blocking probability and fairness is obtained and the performance of FF/lowest algorithm is best among the three kinds of RWA.
