Abstract:

Lightpath connection provisioning problem for capacity upgradeable transparent optical networks with hybrid line rates, modulation formats and dynamic dispersion compensation characteristic are investigated. Two impairmentaware routing, wavelength and compensation assignment algorithms are proposed. Simulations show that the proposed algorithms can improve the network performance significantly with much lower blocking probability, compared to the existing impairmentaware routing and wavelength assignment algorithms.
