Routing and Spectrum Assignment Algorithm with Traffic Prediction and Periodic Rerouting in Elastic Optical Networks

An Iterative Optimization Approach for Routing, Modulation, and Categorical Spatial Bandwidth Block Allocation to Improve Network Performance for Dynamic Traffic in Elastic Optical Networks

“…There are algorithms [14], [15] which are adaptive in nature and compute paths between transponders at the time of lightpath establishment to support dynamic network operation. Adaptive routing [16], [17] tries to establish lightpaths between transponders using link-state information and using all possible routes between transponders. Therefore, it provides lower bandwidth blocking probability compared to k SPF routing at the cost of lightpaths set up times.…”
