Abstract
The introduction of space division multiplexing (SDM) is a promising solution to cope with ever-increasing Internet traffic. Multi-core fibers (MCFs) are a potential solution for the capacity crunch problem. In this article, the Routing, Baud rate, forward error correction (FEC) Coding, Modulation Level, and Spectrum Assignment (RBCMLSA) problem in elastic optical networks (EONs) employing MCFs and SDM is studied. An Integer Linear Program (ILP) model is used to define the studied problem and find the optimum solution in static traffic. Since the RBCMLSA problem is an NP-hard problem, for the dynamic traffic, the crosstalk-aware path routing algorithm (CAPRA) is proposed to solve this problem. Three core-selecting schemes, named Minimum Load (ML), Minimum Conflict (MC), and Minimum Weight (MW) are proposed. Simulation results show that the proposed algorithm can get lower blocking probability when compared to the algorithm for the existing simpler Routing, FEC Coding, Modulation Level, and Spectrum Assignment (RCMLSA) and Routing, Modulation Level, and Spectrum Assignment (RMLSA) problems.
