Design of QoS aware light path provisioning mechanisms in WDM network

Abstract

In this paper, we explore the issue of connection provisioning and performance analysis in WDM network ensuring the QoS requirement of the connection requests from the client in the network In optical networks. While designing WDM system, we must consider the physical layer impairments (PLIs) incurred by non-ideal optical transmission media, accumulates along the optical path. For high transmission speed Dispersion become a considerable degradation factor and in this work we have concentrated on the effects of dispersion on fiber design parameters such as bandwidth, delay and bit rate. The overall effect of dispersion is described in terms of Q-Factor and dispersion penalty. In this project,we worked on light path provisioning mechanism based on Q-Factor and dispersion penalty. Each path is provisioned satisfying the requirement of client in the network model. This work discusses the improvement in blocking probably for incoming requests while performing routing by proposed algorithm and the traditional shortest path algorithm.
