Spectral Efficiency Optimization in Flexi-Grid Long-Haul Optical Systems [PDF]
Journal of Lightwave Technology, 2014 Flexible grid optical networks allow a better exploitation of fiber capacity, by enabling a denser frequency allocation. A tighter channel spacing, however, requires narrower filters, which increase linear intersymbol interference (ISI), and may ...

On the benefits of differentiating the filter configurations in flexi-grid optical networks
2014 The European Conference on Optical Communication (ECOC), 2014 An effective strategy exploiting differentiated filter configurations in flexi-grid optical networks is proposed and evaluated. Results show that 15% throughput improvements can be achieved with respect to traditional flexi-grid approaches.Peer ...

IDEALIST control and service management solutions for dynamic and adaptive flexi-grid DWDM networks [PDF]
, 2013 Wavelength Switched Optical Networks (WSON) were designed with the premise that all channels in a network have the same spectrum needs, based on the ITU-T DWDM grid.

Using a desktop grid to support simulation modelling [PDF]
, 2006 Simulation is characterized by the need to run multiple sets of computationally intensive experiments. We argue that Grid computing can reduce the overall execution time of such experiments by tapping into the typically underutilized network of ...

IDEALIST control plane architecture for multi-domain flexi-grid optical networks [PDF]
2014 European Conference on Networks and Communications (EuCNC), 2014 The IDEALIST (Industry-Driven Elastic and Adaptive Lambda Infrastructure for Service and Transport Networks) project has designed and implemented a Generalized Multi Protocol Label Switching (GMPLS) control plane for flexi-grid optical Dense Wavelength Division Multiplexing (DWDM) networks, providing significant input for IETF standardization.

An OLS Controller for Hybrid Fixed / Flexi Grid Disaggregated Networks with Open Interfaces [PDF]
Optical Fiber Communication Conference (OFC) 2020, 2020 We report the design and implementation of an OLS controller in a hierarchical (partial & full) disaggregation, using open standard data models. We detail the constrained path computation in hybrid fixed/flexi networks and its testbed validation.
