Characterization and performance study of IP traffic in WDM networks

This paper investigates the characteristics of network performance, when IP traffic is directly mapped into WDM networks using multiprotocol label switching (MPLS) techniques. The performance analysis focuses on the burstiness of IP traffic that may have a remarkable effect on the network performance. On the other hand, the inter-channel interferences caused by fiber nonlinear effect such as four wave mixing are also considered in the performance analysis. The statistics of network performance in terms of packet error probability, packet error free-run distribution and packet error-pattern distribution are presented. These illustrative results provide valuable information to the network designers.
