Abstract
A dynamic routing and wavelength allocation technique with interplay between physical and network layer parameters encompassing four-wave mixing (FWM) awareness and the teletraffic performance of wavelength-routed optical networks has been proposed under a distributed approach. In this paper we present an online RWA encompassing FWM-induced crosstalk based upon an impairment-constraint-based routing (ICBR) called FWM-aware dynamic RWA. Our model design assumes a realistic scenario and leads to better network performance comparing to previous work approaches. A fast computational scheme in order to minimize the time of establishing a lightpath dynamically, is also evaluated, for this purpose a precomputed matrix of FWM crosstalk products is proposed and introduced into the mxFWM-aware RWA. The approach is validated through simulations showing improvement up to 30-50 percent on the provisioning time of lightpaths for different network topologies compared to a full on-line computational scheme or FWM-aware RWA.
