We introduce a mixed-integer optimization model for two-layer IP-over-Flexgrid networks, and present a cost study performed using the CPLEX package for the introduced model. The study concerns a generic German network with 12 nodes and 20 links in the optical layer, and a set of six IP traffic matrices with increasing demand volumes. The optimization assumes a hot-standby mechanism in the optical...
Closed-form analytical expressions for nonlinear noise power FWM density (IFWM) have been derived for Nyquist WDM systems as a function of the optical fiber and system parameters (i.e. dispersion, nonlinearity, power spectral density, and spectral efficiency) in case of near-zero fiber attenuation.
