Abstract
Service provider networks are becoming increasingly complex with multi-domain and multi-layer capabilities. Multi-layer optimization has been proposed as a mechanism for planning provider-networks focused on optimizing revenue and reducing capital expenditure. In this paper, we study multi-layer optimization from the perspective of deploying services so as to reduce the capital expenditure in provider-networks. To this end we propose a 3-layer network hierarchical model based on IP, OTN and DWDM technologies. In this paper, we propose an optimization model, a heuristic algorithm and their solution methods. While the optimization model deals with the network planning cases involving static traffic demands, the heuristic algorithm solves the dynamic case. We also develop a simulation model to validate our optimization and heuristic approaches.
