Analysis of Network Throughput and Link Failure Impact in Photonic Switched Metro-Access Networks

Here we investigate the performance of optical packet/burst switched (OPS/OBS) architectures connected as mesh and as ring topologies, to be applied in future optical metropolitan networks, bringing more transparency to these networks. Network throughput and protection to link failure under uniform traffic distribution is investigated in order to evaluate the sensitivity of OPS/OBSN performance. Our results are based on analysis of simulations and comparison between various mesh (Manhattan St. type) and ring topologies. We also consider the traffic distributions over the network links and the impact caused by failure of different links, thus providing a way to select protection deployment.
