Fragmentation and ISRS-Aware Survivable Routing, Band, Modulation, and Spectrum Allocation Algorithm in Multi-Band Elastic Optical Networks

Applied Sciences
The C+L band elastic optical networks (C+L-EONs) increase the network capacity significantly. However, the introduction of an L band enhances the inter-channel stimulated Raman scattering effect (ISRS), consequently deteriorating the quality of ...

Solving Routing and Spectrum Allocation Related Optimization Problems [PDF]

39th European Conference and Exhibition on Optical Communication (ECOC 2013), 2013
We provide a comprehensible introduction to RSA-related problems in flexgrid networks. Starting from its formulation, we analyze network live cycle and indicate different solving methods for the kind of problems that arise at each network phase: from the initial network planning to network re-optimization, going through network operation.
