Reliable, secure and time-synchronised data exchange for autonomous vehicles—both inside a vehicle (threads in one process) and between vehicles (raw-Ethernet broadcast).
| Stage | Core Feature |
|---|---|
| P1 | Raw-socket Ethernet stack (SocketEngine, NIC, Protocol, Communicator) |
| P2 | Shared-memory / in-process routing |
| P3 | Time-triggered publish–subscribe (Interest/Response) |
| P4 | PTP-based clock sync + message MAC authentication |
| P5 | Virtual collision domains & RSU key exchange |
| P6 | Performance optimisations |
| P7 | Integration with real world data |
- Intra-vehicle messages are sent by the
Agentto theCAN BUSand routed to the otherAgents. - Inter-vehicle messages are sent by the
Agentto theCAN BUS, routed to theGatewaywhere they go down the stack and are broadcasted. - Dual Observer patterns decouple layers and provide thread-safe delivery.

# Build library and run ALL tests (unit → integration → system)
makeThe build creates a dummy network interface; real interfaces remain untouched.
