Abstract
Due to huge size of the data and quick transmission of data between the nodes present in the optical network, a condition of network traffic is created among the nodes of the network. This issue of traffic can be overcome by employing numerous traffic grooming techniques. In this research paper, the best suitable shortest path is determined by the multi objective modified PSO algorithm and an innovative visibility graph based Iterative Hungarian Traffic grooming algorithm is implemented to reduce the blocking ratio through improving the allocation of bandwidth between the users. Then finally the performance analysis is carried out by means of performance measures such as traffic throughput, transceivers count, average propagation delay, blocking ratio, and success ratio. It can be inferred that the proposed work obtains enhanced outcomes when compared to the other existing techniques.

Summary
Optical Networks incorporate the use of light signal to transmit information to various categories of telecommunications networks. Route through communication channel using optical time division multiplexing (OTDM) technology. To meet the emerging need and growth of Internet data, elastic optical networks (EONs) have recently emerged as an effective solution that can adapt to real-time and data transfer capabilities and effectively manage network resources. Traffic Grooming incorporates into the optical Network for efficient multiplexing/ demultiplexing and switching of low-speed streams to/from high-bandwidth channel. Traffic Grooming enables network building and provision of resources that can qualify cost-effective use of both network bandwidth and electronic switching.
