SNCP Configuration
Subnetwork connection protection (SNCP) rings can be provisioned using CTC. SNCP rings provide duplicate fiber paths in the network. Working traffic flows in one direction, and protection traffic flows in the opposite direction. If a fiber break occurs in the working path, the receiving node switches to the protect path coming from the opposite direction. Switching in SNCP networks normally occurs at the end of the path and is triggered by defects or alarms along the path.
The SNCP network can be divided into a number of interconnected subnetworks. Within each subnetwork, protection is provided at the path level, and the automatic protection switching between two paths is provided at the subnetwork boundaries. The node at the ...
