TSN is unique in that its streams are delivered with guaranteed bandwidth and deterministic latency
The synchronization is based on IEEE 1588-2008 protocol. A specific profile is defined at IEEE 802.1AS.
The concept of preemption is supported in TSN. A higher priority frame can interrupt the lower priority frame transmission in order to reduce the latency of time-sensitive streams (IEEE 802.1Qbu & IEEE 802.3br).
In order to achieve the theoretical lowest possible latency in engineered networks, the Time Aware Shaper functionality is introduced in TSN. This works with applications where time-critical data is sent on regular periodic intervals and it is based on adding time gates on each queue on a port.
The high-availability on TSN can be achieved by adding frame replication and elimination as defined in IEEE 802.1CB. In a similar way as defined for HSR, the frames include a sequence number and they are replicated. Each copy is sent through a different path in the network.
