AISMixer Wiki

AISMixer is a Python service for processing AIS NMEA 0183 !AIVDM and !AIVDO streams. It receives data through plain UDP ingress and authenticated UDPSEC ingress via nmea_sproxy, extracts AIS sentences, assembles multipart messages, handles NMEA TAG s/c/g metadata, deduplicates output, applies logical routing, and forwards selected traffic to named UDP targets.

The runtime is split into a data plane and an optional control plane. The data plane handles transport ingress, normalization, routing, and UDP egress. The control plane, when explicitly enabled, lets local operators inspect, replace, or disable the process-local routing snapshot through a Unix-domain NDJSON socket.

Use the main repository README for quick start and operator orientation. Use this Wiki as the detailed reference for routing, configuration, runtime control, and architecture.

Runtime Routing Scope

Runtime routing control is opt-in. It is disabled unless control.unix.enabled: true is configured.

Runtime routing state is process-local and non-persistent. A routing.replace or routing.disable request updates only the running AISMixer process that owns the Unix socket. It does not update config.yaml, does not survive restart, and does not synchronize across multiple processes.
