Abstract:This article focus on the routing strategy for burgeoning optical networks and a Path Computation Element (PCE)-based fast routing strategy upon ASON/GMPLS optical networks was proposed.The computation capability of PCE makes fast routing possible in large-scale multi-layer multi-domain optical networks. The performance of the strategy is verified by theoretical analysis and simulation work includes performance improvement on flooding suppression capability, routing delay and traffic blocking probability. The … Show more
