Abstract

In all-optical networks, physical impairments and latency have become two major concerns as they can limit the network performance for large dense wavelength-division multiplexing (DWDM) network. Routing based on impairment effects and latency is an open research problem. In this paper, we propose several adaptive distributed routing policies accounting for BER and latency constraints for optical networks. Results of simulations show that the BER and delay impact the choice of routing policy greatly, and that the routing algorithm should be chosen depending on the traffic load or the application of the network in order to achieve the best performance.
