Abstract

In this paper the influence of routing and wavelength assignment (RWA) algorithms on the blocking probability in wavelength division multiplexing (WDM) all optical network under the condition of static routing was studied. The Single Route and Reroute routing strategies, longest path first (LPF) and shortest path first (SPF) wavelength assignment strategies were compared respectively. In moderately connected network, it is proved by numeric simulation that lower blocking probability can be obtained by Reroute and SPF strategy in virtual wavelength path (VWP) mode. While in wavelength path (WP) mode, when the traffic load is low, Reroute and LPF strategy should be adopted; when the traffic load is high, Reroute and SPF should be adopted. In lowly connected network, Reroute strategy has no effect, so Single Route can be used combined with SPF strategy.
