The role of the TSN controller in E2E deterministic services provisioning

The provisioning of deterministic services over E2E multi-technological infrastructures requires the proper configuration of the resources to match the required Key Performance Indicators (KPI), such as latency and jitter. From an architectural point of view, such configuration is carried out by an SDN-based TSN Controller that has the responsibility to control multiple technologies. In this paper, the main challenges of the TSN controller in such scenario are deeply discussed and its role and implementation in the TIMING architecture is also discussed.
