IEEE 802.1Qch cyclic queuing and forwarding standard

E7400

The IEEE 802.1Qch cyclic queuing and forwarding standard is a Time-Sensitive Networking (TSN) specification that defines cyclic transmission mechanisms in Ethernet bridges to provide deterministic, low-latency, and low-jitter packet delivery for real-time applications.
