Abstract :
A dynamic impairment-aware RWA algorithm is proposed in this paper. By jointly consideration of both available wavelength and wavelength dependent impairments, the routing weight functions can be dynamically updated to accommodate between wavelength blocking and physical layer blocking. Simulation results indicate that the proposed algorithm can achieve lower blocking probability.
