Abstract

This paper proposes a core and spectrum allocation algorithm for optical networks based on multi-core fiber. In this context, the algorithm for reducing fragmentation and crosstalk (AMIFRAC) is proposed. The AMIFRAC implements mechanisms to reduce spectral fragmentation and inter-core crosstalk in the network, proving efficient compared with seven other algorithms in the literature. The numerical results show that when compared with the most competitive of the seven algorithms, AMIFRAC achieves: i) a gain in terms of circuit blocking probability of at least 40.45%; a gain in terms of bandwidth blocking probability of at least 43.95%; and an increase in spectral utilization of at least 5.30%.
