Erlang Distribution via UDP combined with Ethernet TSN
summary
Prototype implements Erlang distribution over UDP using the pluggable distribution API and GenUDP, opening per-node UDP ports via EPMD and numbering every process pair so every message is sequence-numbered per-stream fragments. Large messages get chopped and sent round‑robin across streams to remove head‑of‑line blocking; microbenchmarks show tail latency becomes much more linear versus TCP. Prototype works on loopback and on wire but drops under heavy UDP load and is not production ready. Integrates with Ethernet TSN features like qbv scheduling and PTP time sync for low‑latency, reserved paths.
