Provisioning of Time-Sensitive and non-Time-Sensitive Flows on a Common Infrastructure

Provisioning Time-Sensitive (TS) flows on dedicated infrastructures requires just calculating the time-slot
dedicated to that service, which is then allocated in the superframes used by the schedulers running in the different
nodes in the network. In such scenario, there is no impact on the flows already being served by the network as
every TS flow has dedicated resources supporting it. However, in heterogeneous scenarios supporting TS and non-
TS flows, the impact on existing non-TS flows can be very severe, and needs to be analyzed. In this paper, we
overview a provisioning process that includes the use of a Network Flow Scheduler for reserving time slots for TS
flows and a Digital Twin to accurately estimate the performance of the new and already deployed non-TS flows.
