The provisioning of time sensitive end-to-end services in future 6G networks imposes multiple technical challenges, spanning from the data plane to the control and orchestration planes. In particular, the automation of the provisioning and maintenance of connectivity services with deterministic constraints over multiple technology/administrative domains requires control and orchestration solutions able to assure the strict time service requirements. In line with that, the paper investigates some requirements imposed to the control and orchestration planes and it also shows potential enabling architectures for end-to-end service guarantees.
