Abstract

WDM optical networks represent the direction to the future high capacity wide-area network applications. By creating the optical paths between 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 IP over WDM 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 propose a different simulated annealing approach to determine a better logical topology within shorter time period.
