A heuristic for routing, modulation and spectrum allocation in spectrum sliced elastic optical path network

The recently proposed spectrum sliced elastic optical path network (SLICE) is expected to substantially increase network resource utilization efficiency. In order to meet this high expectation it is necessary to provide an efficient solution to the NP-complete routing, modulation and spectrum assignment (RMSA) problem. In this paper, we propose a new heuristic to solve this problem for generic networks. We show through extensive simulations that this heuristic can provide competitive performance when compared to several existing algorithms.
