Segment Routing enabling dynamic optical bypass in a multi-layer network is experimentally demonstrated. Edge nodes are efficiently configured by an enhanced SDN controller, showing effective scalability performance under different label stacking conditions.
We present a platform for the optical interconnection of traffic nodes where the sense of transmission is exploited as an additional degree of flexibility. Implementation of the optical arrangement is shown. The requirements about the negotiation of the available resources, such as fibers and wavelengths, are discussed. We evaluate the implications of flexible-sense transmission in terms of cost,...
We propose a scheme for efficient power control in 100G optical transponders through reduction of the length of electronic chromatic dispersion compensation filters, according to the network traffic fluctuations. Transmission rate reduction is achieved by symbol retransmission, while maintaining system parameters unchanged, to avoid increased complexity. Power savings offered by the scheme are estimated.
We investigate possible evolutions of an optical backbone over TrueWave-RS. Maximum inter-capital capacity is obtained with fixed-grid 50-GHz spaced DP-QPSK 100G wavelengths when the interplay between spectral efficiency and XPM is considered.
An efficient defragmentation technique based on optical channel re-tuning is proposed for flexible optical networks. Effective defragmentation with no traffic disruption is achieved without additional spare transponders or re-equalization operations.

A method to mix impairments estimations and in-field measured data is proposed to evaluate the Quality of Transmission of new lightpaths. It is applied before lightpath establishment and increases the reliability of QoT estimation.
An effective lightpath provisioning is proposed for PCE-based optical networks with flexible grid. The expected modulation formats at 400 Gb/s are considered showing that 12.5 GHz spacing is satisfactory to guarantee efficient network resource utilization.
