Abstract: With the ever-increasing demand for data transmission in our generation where Internet and cloud concepts play a vital role, it has become very essential that we handle data in a most efficient way. A possible solution is to overcome the capacity crunch problem with applications of Space Division Multiplexing, where we explore the remaining unused domain that is the spectral and spatial domain. Space Division Multiplexing using multi-core fibers (MCFs), and few-mode fibers (FMFs) has been studied in our work to enhance the data-carrying capacity of optical fibers, while minimizing the transmission cost per bit. The objective of our work 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 the previously allocated lightpaths, 2) allocate spectrum using the flex-grid flexible-SDM model, 3) choose the best possible path to minimize the number of sub carriers needed for data transfer, 4) measure the cost of the resources required to handle the new requests. We propose to evaluate the developed Integer Linear Programming (ILP) formulation based on this scheme.
