A Study on Layer Correlation Effects Through a Multilayer Network Optimization Problem

Multilayer network design has received significant attention over the years. Despite this, the explicit modeling of three-layer networks such as IP/MPLS-over-OTN-over-DWDM in which the OTN layer is specifically considered has not been addressed before. In this paper, the authors present an optimization model for network planning of such multilayer networks that consider the OTN layer as a distinct layer with its unique technological sub-layer constraints. More importantly, they present a comprehensive study to quantify the interrelationship between layers through change in unit cost of elements and capacity modularity, coupled with network demand.
