Paper Abstract

This paper studies wavelength converter placement problem in wavelength-routed all-optical networks with dynamic traffic demand. We propose an analytical model to determine path usage probabilities for different routing policies and calculate the transit traffic for each node to evaluate the suitability of placing a converter at that node. With this, a heuristic algorithm, named maximum transit traffic (MTT), is proposed. Simulation results demonstrate the effectiveness of the proposed MTT algorithm.
