Abstract: | Due to the huge size of the data and quick transmission of data newlinebetween the nodes present in the optical network, a condition of network traffic newlineis created among the nodes of the network. Hence research in this field revives newlineday by day to satisfy the present end users with the needed Quality of Service newline(QoS). Security issues and attack management is also become an emerging field newlinein the optical network to provide end-user QoS. This issue of traffic can be newlineovercome by employing proper Routing and Wavelength Assignment (RWA) newlineproactive and reactive techniques. In this research work, the best suitable path is newlinedetermined by the multi-objective modified Particle Swarm Optimisation (PSO) newlinealgorithm and it is used for locating the position of the failure through finding newlinethe fitness value of the aforementioned links. The greedy algorithm is used for newlinewavelength assignment. The novelty of this work exists in the form of a fitness newlinefunction that uses bandwidth availability and packet delay as parameter metrics newlinethat ensure the quality of the link paths. The proposed work has been extended newlineby employing an innovative visibility graph-based Iterative Hungarian Traffic newlinegrooming algorithm is implemented to reduce the blocking ratio by improving newlinethe allocation of bandwidth between the users. Then finally the performance newlineanalysis is carried out employing performance measures such as traffic newlinethroughput, transceivers count, average propagation delay, blocking ratio, and newlinesuccess ratio. It can be inferred that the proposed work obtains enhanced newlineoutcomes when compared to the other existing techniques newline |
