The recent advances in optical technologies pave the way to the deployment of high-bandwidth services. As reliability becomes a mandatory requirement for some of these services, network providers must endow their networks with resilience capabilities. In recent years, network coding protection (NCP) has emerged as a tentative solution aiming at enabling network resilience in a proactive and efficient way. The goal of this paper is to conduct a techno-economic study to evaluate the protection cost required by NCP schemes deployed either at the IP/MPLS or at the Optical layer of a multi-layer network, as well as its impact on both the capital and operational expenditures (CAPEX, OPEX) of a network provider. Our evaluation results show that a significant reduction in both CAPEX and OPEX is obtained with NCP. Indeed, at least a 49% and 52% of CAPEX and OPEX reduction is achieved respectively in comparison with conventional proactive protection schemes.
