Physical Layer Impairments based Data-path Routing in WDM Network

Abstract

In WDM network, the quality of data flow depends not only on network layer information, but also on physical layer impairments (PLIs) constraints, which are incurred by non-ideal optical transmission media and accumulates along with the optical data-path. It is important to analysis PLIs in-order to satisfy client’s necessary requirement of QoS for their data flow. In-corporate to the above point, the design methodology says how to understand the process that provide PLI information to the control plane protocols and use this information efficiently to compute feasible routes. Based on the PLI impairments, it is proposed a centralized PLI based routing algorithm for the selection of data-paths.
