Abstract(in English)	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. In this paper we consider the method of designing logical topology in wavelength routed all optical networks. The exact formulation of the logical topology problem is usually given as a Mixed Integer Linear Problem, 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, and compare it with other methods.
