Design and re-optimization algorithms for elastic optical networks

Basic RSA-based problems have been reviewed Off-line planning: Examples for national IP/MPLS Networks and for gradual migration process from fixed to Flexgrid has been presented. Re-optimization can be performed to increase network performance. Examples included defragmentation and after failure repair optimization In-operation planning and holistic planning extended the networks life-cycle. Data analytics were introduced as a way to add cognition to the network.
