Alternative homing architectures can lead to significant cost reductions. These reductions are quantified using linear programming under a multi-layer consideration. In this paper we focus on the CAPEX savings achieved by transitioning to different homing architectures in an IP-over-OTN setting. The impact of traffic demand is examined for different reference networks. Additionally, it is shown that...
Alternative homing architectures can lead to significant cost reductions. Using linear programming we quantify these reductions for IPoWDM and IPoOTN networks under a multi-layer consideration for a reference network topology and varying traffic demand.
A generic multi-layer model and a linear programming (LP) formulation are developed enabling the calculation of the optimal solution in terms of network equipment capital expenditures (CAPEX) in multi-homing design. Alternative homing architectures to traditional dual homing are studied not only with respect to network equipment costs but also regarding the achieved availability gain. Case study results...
