Optimized traffic profile for FlexGrid optical networks [PDF]
Photonic Network Communications, 2017 This work is focused on studying the connections’ bandwidth distribution effects on the FlexGrid network performance. An accurate study of spectrum occupancy in heavy loaded FlexGrid optical networks is carried out. This analysis is useful to figure out which traffic profiles are more suitable for this kind of networks.

On the performance of flexgrid-based optical networks [PDF]
2012 14th International Conference on Transparent Optical Networks (ICTON), 2012 The ever increasing IP traffic volume has finally brought to light the high inefficiency of current wavelength-routed rigid-grid networks in matching the client layer requirements. Such an issue results in the deployment of large-size, expensive and power-consuming IP/MPLS layers to perform the required grooming/aggregation functionality.

Planning fixed to flexgrid gradual migration: drivers and open issues
IEEE Communications Magazine, 2014 Flexgrid technology has recently been presented as the most promising option for upgrading the currently operating fixed grid optical networks and extending their capacity to be able to deal with the massive traffic volumes forecast for the next decade.

Extending the flexgrid optical core towards the edges
2013 15th International Conference on Transparent Optical Networks (ICTON), 2013 National IP/MPLS network have being designed on top of fixed-grid DWDM optical networks so to spread out covering large areas. Besides, multilayer IP/MPLS-over-DWDM networks take advantage from grooming to achieve high spectrum efficiency, filling the gap between users' flows and wavelength channels' capacity.

Experimental Assessment of ABNO-Driven Multicast Connectivity in Flexgrid Networks [PDF]
Journal of Lightwave Technology, 2015 The increasing demand of internet services is pushing cloud services providers to increase the capacity of their data centers (DC) and create DC federations, where two or more cloud providers interconnect their infrastructures. As a result of the huge capacity required for the inter-DC network, the flexgrid optical technology can be used.

Energy efficiency of elastic frequency grids in multilayer IP/MPLS-over-flexgrid networks [PDF]
Journal of Network and Computer Applications, 2015 Flexgrid Optical Networks provide higher spectrum efficiency and flexibility in comparison to traditional wavelength switched optical networks (WSON) due to the finer granularity in managing communication channels at the WDM layer, thus allowing beyond ...

QoS-Aware Protection in Flexgrid Optical Networks
Journal of Optical Communications and Networking, 2017Elastic optical networks generally rely on protection and restoration mechanisms to prevent the detrimental effect of fiber cuts. In particular, we investigate optical protection in flexgrid optical networks where the symbol rate is varied as a complementary approach to modulation format.

Trading off Transponders for Spectrum in Flexgrid Networks
Optical Fiber Communication Conference/National Fiber Optic Engineers Conference 2013, 2013We propose algorithms for planning flexgrid networks under physical layer impairments. Using an optimization function that accounts for both the spectrum used and the transponders cost, we observe tradeoffs between these two optimization parameters.
