- SNCP Protection: SNCP protection offers the added security of a second route without the hassle of a second circuit. This protection mode is implemented using the SNCP protection offered by the DTN-X. With this option enabled, GÉANT Lambda is able to reroute under 50ms in case a single circuit failure occurs. Protected lambdas can be provided with auto-recovery, meaning the service is automatically switched back to the original circuit when restored, or with manual switching back to the original circuit by DANTE GÉANT at an agreed time.
- Full Fibre and Optic Protection (1+1 protection): The 'fully protected' option offers a complete backup path, including the client interfaces. This option offers two GÉANT Lambdas routed over different paths, leaving it up to the user to select which one to use.
