Abstract: Space division multiplexing (SDM) using multi-core fibers (MCFs), and few-mode fibers (FMFs) has been proposed to enhance the data-carrying capacity of optical fibers, while minimizing the transmission cost per bit. The objective of this investigation is to develop a path protection scheme to handle communication requests in data center (DC) networks using elastic optical networking and space division multiplexing (SDM). Our approach to this problem is to 1) determine a dedicated primary path, 2) possible allocation of spectrum using the flex-grid fixed-SDM model, 3) choose the best possible modulation format to minimize the number of subcarriers needed for data transfer, 4) measure the cost of the resources required to handle the new requests, 5) determine the replication strategy for all disaster scenarios including the setting up of the backup paths. We propose to develop a new Integer Linear Programming (ILP) formulation based on this scheme, considering the possibility of disasters. We will study the impact of the design on the cost of the solution, and explore whether it promotes significant resource savings.
