Practical TSN; using NetChan for distributed PoC
summary
NetChan is a small C library for Linux that wires TSN into prototypes using PTP, SRP, MQ prio, CBS and the earliest-transmission-first / launch-time hooks on Intel i210/225 NICs. A distributed UR10 + IMU controller is implemented via libURx and multicast channels, IMU at 10 ms and control loops at 2 ms, and all protected streams arrive without loss and within the 2 ms guarantee; clocks sync to about 11 ns and wake jitter is ~16 µs with rare 180 µs outliers.
