Are control plane benefits applicable to submarine networks?

Conclusion

Yes

Fully relevant to manage complex networks (topology and provisioning) Fully relevant to manage complex networks (topology and provisioning) Save efficiently protection ressource (granularity, sharing)

Even if

Not many additional features for simple topologies It may make sense to activate preferably CP at operator backhaul layer (expensive) "Earth is a single point of failure"
