Design Of QOS Aware Light Path Planning And Technical Aspects In Wdm Networks

In this work, the issue of connection provisioning and performance analysis in wavelength division multiplexing (WDM) network is considered. We ensured the quality of service (QoS) requirement of the connection requests from the client in the optical networks. While designing WDM system, the physical layer impairments (PLIs) incurred by non-ideal optical transmission media, accumulates long the optical path degraded the QoS. For high transmission speed Dispersion become a consider able degradation factor and in this work will be concentrated on the effects of dispersion on fibered sign parameters such as band width, delay etc. The overall effect of dispersion is described in terms of quality factor (Q-Factor) and improvement in blocking probability is observed over proposed algorithms and traditional algorithms. In this work the light path provisioning mechanism is based on both Q-Factor and blocking probability. Each path is provisioned that satisfy the requirement of client in the network model. A proposed algorithm and the traditional algorithm provide the improvement in blocking probability for incoming requests while considering impairment issues. In this work, the impact of dispersion on transmission performance of WDM network, by ensuring the QoS requirements, is evaluated. It is necessary to provide the best service to the customers. The aspect WDM network model can be specified in terms of QoS parameters such as bandwidth and delay. The QoS requirement, in terms of Q-Factor, is associated with the optimum light path. For high transmission speed, the dispersion becomes a considerable degradation factor.This work improves the blocking probability while performing the optimum routing
