Abstract

Alternative homing architectures can lead to significant cost reductions. These reductions are quantified using linear programming under a multi-layer consideration. In this study we focus on savings with respect to network equipment capital expenditures (CAPEX) achieved by transitioning to different homing architectures in an IP over optical data unit (ODU) setting. The impact of traffic demand is examined for different reference networks. In all conducted case studies we find that network equipment costs follow an approximately linear relationship with the traffic demand. Additionally, case study results assuming up to an aggressive 50% cost decrease in IP layer equipment, quantify the impact of variations in the cost of network elements.
