Abstract:
This paper proposes a dynamic routing and spectrum allocation method that avoids the generation of crosstalk and the blocking of lightpath establishment in elastic optical networks with multi-core fibers. In the elastic optical networks with multi-core fibers, crosstalk occurs when the same frequency band is used for signals of adjacent cores. The proposed method provides a routing and spectrum allocation strategy, which suppresses the generation of crosstalk by avoiding using the same frequency band in adjacent cores and blocking of lightpath establishment by selecting appropriate routes. Through simulation experiments, we show the effectiveness of the proposed method.
