Time-Sensitive Networking (TSN) Enabling on StarlingX
summary
StarlingX runs a customized kernel and container image with the TSN stack and passes an Intel I210 NIC into Kata containers to enable 802.1Qbv time-aware shaper and ETF/CBS qdiscs, using iproute2, tc, ethtool and linuxptp for PTP sync. An experimental 4-node setup sends ~10,000 packets at 1.25 ms period and shows scheduled times ≈1253 µs with jitter <100 ns while OS latency ranges 3–758 µs. Under stress with iperf at ~956 Mbps critical traffic remains deterministic.
