Abstract :
We propose a hybrid control plane architecture, in which both RSVP-TE and OSPF-TE are extended to carry PLIs information and disseminate wavelength availability information, respectively, for impairment-aware routing in transparent optical networks. The results suggest that, hybrid approach provides good trade-off between control overhead and network performance.
