    The all optical network using WDM and optical nodes (OXC's) seems to be a possibility in a near future. The consensus to day seems to be that optical wavelength conversions is un-realistic for several decades, hence wavelength blocking will happen in the all optical networks. A possible solution to this problem could be to include digital nodes (DXC's) in the network at the right places. In this article we present a linear programming model which optimizes the placement of these more expensive DXC's in the network.
