Finding an objective cost for sliceable flexgrid transponders [PDF]

, 2014
We analyze the objective cost of SBVTs as a function of the traffic conveyed by IP/MPLS-over-flexgrid networks. Optimal results show that cost increment with respect to BVTs is related to the aggregation level.Postprint (published ...

FlexGrid optical network simulator implementation

, 2016
A study about EON has been realized. Firstly, the capacity and fragmentation of EON network has been studied; study published in (Jaume, Xavier y Gabriel, Efficient spectrum assignment in Elastic Optical Networks 2016). Then, a study about the measurement of transceivers of EON was done.

Designing national IP/MPLS networks with flexgrid optical technology

We propose a two-step procedure to design flexgrid-based national networks. Locations are first partitioned into a set of metro areas interconnected through a flexgrid optical network. Next, each network is designed separately.

Path-based recovery in flexgrid optical networks

With the advent of flexgrid optical networks, the rigid wavelength-division multiplexing (WDM) technology will be enhanced by providing better spectrum efficiency and flexibility. In those future flexible optical networks, optical connections (lightpaths)

Filter optimization in SDN-based flexgrid networks

The novel super-filter technique for flexgrid optical networks is proposed to compact spectrum-contiguous lightpaths. The technique is applied in a specifically extended SDN architecture, showing significant gains in terms of spectral efficiency.Peer ...
