In this paper, we analyze the optical network with wavelength conversion, and discuss the architecture of network with wavelength converter in its node. The optical cross connects technology for wavelength division multiplexing (WDM) is rapidly developing. Wavelength conversion is one of the key techniques for switch WDM optical networks. The wavelength conversion technology can achieve wavelength reuse, decrease wavelength competition, enhance network flexibility and scalability, and simplify network structure and management. The results show that If these cross-connectors feature integrated with wavelength conversion, network will be better able to play the full potential of WDM optical networks.

Objective: Optical networks exploit the Wavelength Division Multiplexing (WDM) to meet the ever-growing bandwidth demands of upcoming communication applications. This is achieved by dividing the enormous transmission bandwidth of fiber into smaller communication channels. The major problem with WDM network design is to find an optimal path between two end users and allocate an available wavelength to the chosen path for the successful data transmission. Methods: This communication over a WDM network is carried out through lightpaths. The merging of all these lightpaths in an optical network generates a virtual topology which is suitable for the optimal network design to meet the increasing traffic demands. But, this virtual topology design is an NP-hard problem. This paper aims to explore Mixed Integer Linear Programming (MILP) framework to solve this design issue. Results: The comparative results of the proposed and existing mathematical models show that the proposed algorithm outperforms with the various performance parameters. Conclusion: Finally, it is concluded that network congestion is reduced marginally in the overall performance of the network.
