Routing, Spectrum, and Transponder Assignment in Elastic Optical Networks [PDF]

Journal of Lightwave Technology, 2015
Backbone networks are evolving toward Elastic Optical Network (EON) architecture that allows a flexible and efficient use of spectrum resources. Flexibility in EONs is guaranteed also by emerging sliceable bandwidth variable transponders (SBVTs) that support the simultaneous generation of multiple optical carriers.

Tree-determination, routing, and spectrum assignment using point-to-multipoint coherent optics [PDF]

Journal of Optical Communications and Networking, 2023
In this paper, we investigate a novel problem for dimensioning optical networks with digital subcarrier-based point-to-multipoint (P2MP) coherent transceivers, which we refer to as tree-determination, routing, and spectrum assignment (TRSA).
