 note = {In this paper, we consider a reliable routing and spectrum allocation problem in multi-core fiber space division multiplexing (MCF-SDM) networks. By using MCF-SDM technology, we can overcome the limitations of transmission using single-mode optical fibers. However, in a MCF-SDM network multiple cores are contained in the same cladding and therefore the interference (crosstalk) between cores may occur. Furthermore, transmission path may be broken down due to some unexpectable events. In order to prevent the link failure, we consider to set up a backup path for each working path. A backup path may be dedicated to a working path or be shared with other working paths. In this paper, we consider a reliable routing problem using dedicated path protection (DPP) or shared backup path protection (SBPP) approach in MCF-SDM networks. We formulate the routing problem as an integer linear programming (ILP) problem. We compare the performance of these two protection techniques with the total reserve capacity (FS) and the maximum exponent of the FS. The results show that due to the sharing between backup paths (in the common link of the same core), the SBPP technology requires fewer spectrum resources and spectrum bandwidth than the DPP technology., In this paper, we consider a reliable routing and spectrum allocation problem in multi-core fiber space division multiplexing (MCF-SDM) networks.
