A post path calculation process considering the flexibility of rerouting backup paths is proposed in this paper to achieve blocking-differentiated path provisioning for two classes of connection requests in semi-dynamic shared-path-protected optical networks. Numerical results show that with the proposed post routing process, the blocking gap between two request classes is over 90% under all network load cases without increasing the overall blocking probability. Intelligent optical networks, supported by Wavelength Division Multiplexing (WDM) technology, are widely considered to be the direction of infrastructure migration for future backbone networks.
