TL;DR: An RSA algorithm to be used in dynamic network scenarios is presented, the optimal slot width is studied as a function of the foreseen traffic to be served, and an algorithm to reallocate already established optical connections so that to make room in the spectrum for the new ones is proposed.

TL;DR: Different RSA-related optimization problems that arise within the life-cycle of flexgrid networks are reviewed and different methods to solve those optimization problems are reviewed along with the different requirements related to where those problems appear.

TL;DR: This article proposes a control and management architecture to allow the network to be dynamically operated, so that the resource overprovisioning can be minimized and overall network costs reduced.

TL;DR: This paper tackles the multilayer IP/MPLS-over-flexgrid optimization problem with an integer linear programing formulation and a greedy randomized adaptive search procedure (GRASP) metaheuristic, and analyzes the cost implications that a set of frequency slot widths have on the capital expenditure investments required to deploy such a multilayers network.
