defining a network topology of the desired TSN including at least a set of end nodes communicatively connected by way of a set of switching nodes;
defining a set of device parameters for each of the set of end nodes and each of the set of switching nodes of the desired TSN;
receiving, by a TSN scheduler, the defined network topology and at least a subset of the defined set of device parameters for each of the set of end nodes and each of the set of switching;
instructing, based on a user input, the TSN scheduler to utilize a contiguous scheduling mode including a data flow timing buffer to ensure no data flow overlap or collisions are scheduled;
determining, by the TSN scheduler in the contiguous scheduling mode, a back-to-back TSN schedule for the desired TSN based on the defined network topology and at least a subset of the defined set of device parameters for each of the set of end nodes and each of the set of switching nodes;
generating, by the TSN scheduler, a per-device configuration for each of the set of end nodes, based on the back-to-back TSN schedule, and
programming each of the set of end nodes and each of the set of switching nodes with respective per-device configuration data; and
wherein in the event the contiguous scheduling mode cannot be completed, the TSN scheduler is configured to default to another scheduling mode.

2. The method of claim 1 , further comprising defining a set of data flows defining communication pathways between the set of end nodes by way of the set of switching nodes, and wherein determining the back-to-back TSN schedule is further based on the defined data flows.

3. The method of claim 1 , wherein generating the per-device configuration further comprises generating a per-device configuration data file for each of the set of end nodes and each of the set of switching nodes of the desired TSN.

4. The method of claim 1 , wherein programming further comprises at least one of updating each of the set of end nodes and each of the set of switching nodes, based on the respective per-device configuration data, such that each of the set of end nodes and each of the set of switching nodes operate in accordance with the determined back-to-back TSN schedule.
