This paper studies the impact of considering crosstalk effects in the IA-RWA process and in the regenerator allocation algorithms. First of all, the authors evaluate if the regenerator allocation optimization is still useful when the crosstalk effects are considered. For this end they improve a simple physical model which computes the quality of the signal factor for each optical connection. Until now this physical model was unaware of the physical layer impairments depending on the interference between different optical connections, such as the crosstalk. Following the same simple methodology they add the switching node crosstalk effect to the computation of the quality of the signal factor.
