英文摘要：

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 pro- posed. 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.
