Techniques are described herein for enhancing Time-Sensitive Networking (TSN) in network fabrics by dynamically assigning Secure Group Tags (SGTs) based on the stream configuration in a TSN controller. The TSN controller communicates stream details to a policy engine which creates a policy and assigns an SGT for the stream. The TSN controller pushes regular stream scheduling to the network switches, but also pushes a function that maps the stream identification based on the multicast Media Access Control (MAC) to a specific SGT. The TSN stream is now protected by the correct SGTs end-to-end.
