Abstract :
In this paper, we present an optimization design model for protecting an IP/MPLS over OTN over DWDM three-layer network. We provide a protection mechanism at each layer while considering the technological constraints of each layer; especially the OTN layer which has not been explicitly considered before. We present a heuristic approach to reduce the complexity of the problem and present a study based on varying several network parameters to understand their impacts on the protection capacity and the overall network cost.
