Paper Abstract

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 sharedpath- 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.
