Implementation of segmented protection and restoration in PCE-based multi-domain heterogeneous optical networks
This paper introduces the routing and signaling processes of segmented protection and restoration in PCE-based multi-domain heterogeneous optical networks. To evaluate the performance of protection and restoration, a network platform with commercial SDH and OTN equipment is implemented. Results show that the segmented protection and restoration have acceptable performance on the network platform.
