Scheduling Strategy for Multi-Stage Ultra-Low Loss Fiber Deployment in an Elastic Optical Network

Ultra-low loss (ULL) fiber is promising to be widely applied in next-generation optical networks to support future super-channels. In this paper, we studied the multi-stage ULL fiber deployment problem in the context of an elastic optical network (EON) and developed a simulated annealing-based scheduling strategy to select network links for ULL fiber deployment in each stage. Results show that the proposed strategy is efficient to obtain the global optimal solution for the multi-stage ULL fiber deployment.
