Enhancing consecutiveness in elastic optical networks Photonic Netw. Commun. (IF 1.7) Pub Date : 2024-03-04
Abstract The Elastic Optical Network (EON) has brought several studies to improve optical spectrum efficiency. In the EONs, the bandwidth is divided into frequency slot units (FSUs). When a connection is requested for a service type, the network management system determines how many FSUs are required. As the number of service requests increases, the optical network goes into optical spectrum fragmentation

Survivable transparent OFDM optical grids/clouds: fragmentation aware, resource efficient protection with fast failure recovery Photonic Netw. Commun. (IF 1.7) Pub Date : 2024-01-14
Abstract Due to high spectral efficiency and flexibility of orthogonal frequency division multiplexing (OFDM) technology, OFDM-based optical grids/clouds are fast replacing WDM grids/clouds. As grids and clouds process data intensive tasks, protection of optical grids and clouds from an arbitrary fiber-cut is extremely important. Employing a protection scheme leads to idle resource reservation, and
