Abstract :
Dynamic routing and wavelength assignment (RWA) is an attractive method for the efficient use of network resources in all-optical networks. We present a novel fixed alternate routing method referred to as overlap-degree aware (ODA) routing in all-optical network. The authors believe that in order to minimize the blocking probability, it is important to consider not only the consumption of wavelength resources but also the existence of the other flows when a routing decision is made. Our simulation results show that our new routing algorithm outperforms fixed-alternate routing (FAR) and weighted least congestion routing (WLCR) from the viewpoint of call blocking probability.
