Abstract

In this paper, the problem of routing, modulation level, core, and spectrum assignment (RMCSA) in space-division-multiplexed elastic optical networks (SDM-EONs) is studied. We formulate this problem as a mixed-integer linear programming (MILP), in which dedicated and shared path protection schemes are supported in SDM-EONs with multi-core fibers (MCFs) and the inter-core crosstalk of MCFs is strictly modeled. Furthermore, an efficient heuristic algorithm is proposed to solve the RMCSA problem in a large scale scenario. Numerical results reveal that the formulated MILP leads to lower spectrum usage compared to the alternative methods. Moreover, the proposed heuristic algorithm performs close to the MILP formulation with lower computational run-time.
