Bandwidth and Delay are quality parameters that can be guaranteed for new connections that are offered to the network by finding a suitable path in the network. Finding such a suitable path is the task of QoS routing techniques developed for IP Optical networks based on Multiprotocol Label Switching (MPLS). In this paper we focus on dynamic routing of Bandwidth (1Mbps/link) and delay (1ms/link) guaranteed flows in optical networks based on label forwarding techniques. We are presenting simulation results to compare the performances of Optical Networks with Wired networks under wide range of topologies and system parameters. The simulation results show that considering an optical fibre as link, the call blocking ratio is reduced by 2.4% as compared to a non optical link in same topological environment.
