**Sažetak**

We survey some recent results regarding throughput optimization in logically rearrangable multihop lightwave networks. Two cases are distinguished: networks having arbitrary as well as regular connectivity topology. In both cases we present formulation of the combined station assignment/flow routing problem with the congestion minimization objective. We then outline a heuristic solution strategy based on tabu search. In terms of small congestion (as obtained heuristically), the results suggest that with increased problem sizes, regular topologies become more attractive. In such cases the benefit of having less restricted arbitrary network topology might not be fully utilized. We present some results with a combined approach whereby initial assignments to network stations are restricted to a Perfect Shuffle connectivity pattern and obtained by solving a quadratic assignment problem. (In an earlier study, Perfect Shuffle proved to be the most promising among different regular topologies.) Computational results confirmed the possible merit of this approach.
