N2 - WDM optical networks represent the direction to the future high capacity wide-area network applications. By creating the optical paths between several nodes in the core networks, logical topology can be created over the physical topology. The network can dynamically change its logical topology corresponding to the changing traffic conditions. We consider the method of logical topology reconfiguration in wavelength routed optical networks. The exact formulation of the logical topology problem is usually given as a mixed integer linear programming, but it grows intractable with increasing size of network. Heuristic approaches have been proposed, here we also proposed a different heuristic approach to determine the logical topology reconfiguration.
