Resum
The Split Spectrum Approach (SSA) in elastic optical networks is based on splitting a demand into smaller sub-signals when a blocking situation arises, either due to the lack of spectral resources or transmission reach reasons. In this paper, we propose a mechanism based on a Mixed Integer Linear Programming (MILP) formulation for efficiently serving incoming demands in SSA-based elastic optical networks. Moreover, we also present a lightweight heuristic mechanism for scenarios where the MILP me...
