How do you Sub-Network Connection Protection works?

Sub-Network Connection Protection (SNCP) is a mechanism used in telecommunications networks to enhance the reliability and availability of connections within a sub-network. It operates by providing protection for vital data paths, ensuring that if a primary connection fails, traffic can be quickly rerouted through a backup path. This redundancy minimizes downtime and maintains service continuity. SNCP is often implemented in optical networks and is part of the general strategy for resilience in network design.
