Query: A Heuristic Algorithm for Network Optimization of OTN over DWDM Network   While the network traffic has seen exponential increase, the revenues have
not maintained the same pace. New methods have to be explored to reduce this
gap between traffic and revenue. One such method is convergence in networking
layers. In this work, we study the convergence of OTN and DWDM layer from a
network planning perspective. We compare the costs of planning networks without
and with convergence and show that the multilayer planning offers least cost
for higher traffic volumes.
