Abstract :
This paper proposes an MILP (Mixed Integer Linear Programming) formulation for the design of flexgrid optical networks under multiple modulation formats and noise constraints. The proposed MILP benefits from the flexibility of using multiple modulation formats, each of which with its spectrum efficiency and individual noise constraints, to properly perform routing and spectrum assignment of the demanded traffic. The model is capable of maximizing the amount of traffic that is established in the network for a limited number of slots per link. Cases studies are carried out in order to analyze the benefits of the proposal as well as the basic properties of the formulation.
