Time-Sensitive Networking
Also known as: TSN, Time Sensitive Networking
Definition
TSN is a standards-based Ethernet approach that schedules and prioritizes traffic so critical packets meet latency and delivery constraints.
Key Points
- It adds time-aware behavior to Ethernet transport.
- It reduces jitter and bounded-delay uncertainty.
- It depends on synchronized clocks and disciplined transport.
- It is central to deterministic industrial networking.
- It supports mixed traffic when time-critical flows must be protected.
Concept
TSN combines synchronized clocks, traffic shaping, time-aware scheduling, and bounded queuing behavior. The point is not raw speed; the point is predictable delivery for traffic that cannot tolerate missed windows. That makes TSN especially relevant in control networks, industrial gateways, and other mixed-criticality systems.
Explainer
TSN becomes useful when latency variation is the real problem. A faster network that is unpredictable can still break a control loop or a synchronized application. TSN addresses that by making the forwarding fabric aware of time, so critical traffic gets scheduled instead of merely contended for.
