Abstract

In elastic optical networks under dynamic traffic, the routing and spectrum allocation (RSA) are usually executed sequentially in two steps: by solving the routing firstly and then the spectrum assignment for this selected route or prioritizing some spectrum ranges and then searching for a route that meets such SA requirement. This paper proposes a hybrid resource-allocation ordering approach to decide between either strategy. An efficient metaheuristic based on genetic algorithm is proposed to return the best RSA ordering choice for each source-destination pair, which provides the lowest network path-request blocking probability.
