Abstract
Elastic optical networks can efficiently utilize frequency resources in optical networks. Moreover, SDM technology with multicore fiber (MCF) aiming at achieving large capacity transmission has been attracting attention. However, crosstalk occurs due to the signal leaked from the core. In this paper, we propose to reduce call blocking probability, to which we cannot allocate the optical path due to the influence of crosstalk in the elastic optical network using MCF. For this purpose, we proposed core assignment methods and path allocation methods considering crosstalk. Specifically, we utilize the core according to each modulation scheme of the optical path. Then, we allocate the optical frequency spectrum to the path considering crosstalk. As a result of the simulation, we observe that it is possible to reduce the call blocking probability of the optical path. In addition, we can demonstrate that the fairness of call blocking probability can be secured for each optical path modulation scheme.
