Synaptic Data Fabric - The Self-Healing Backbone
The Synaptic Data Fabric (SDF) is the connective tissue beneath VITALNET Mesh. Every sensor stream, every alarm, and every PANACEA query crosses the fabric over the Synaptic Protocol. The SDF is built so that nodes, links, and whole cells can fail without the network failing — telemetry simply finds another path through the mesh.
The Self-Healing Mesh Backbone
The SDF carries all telemetry and PANACEA traffic across the directorate. It is a true mesh — there is no core, no central switch, no single hub whose loss would darken the network. Three design principles define it.
Self-Healing Routing
Each node continuously gossips link health to its neighbours. When a hop degrades or drops, traffic re-converges around the fault in milliseconds — the mesh reroutes around the dead cell without operator action and without losing the stream.
No Single Point of Failure
Every payload has at least two disjoint paths to its destination. Relay masts, drone nodes, and fabric gateways are all redundant, so the loss of any one node — or any one corridor — never partitions the network from PANACEA.
Synaptic Protocol
The Synaptic Protocol lets nodes advertise the best route and cost to a destination, so traffic continuously re-paths around congestion and failure without any central controller. Routes are learned, not configured.
Fabric Layers & Components
The SDF is organised as a stack of layers, each with a defined function and its own redundancy posture. Together they make the fabric self-healing end to end.
| Layer / component | Function | Redundancy |
|---|---|---|
| Field node link | First-hop radio carrying raw sensor frames from unit packages onto the mesh. | Dual-band; each node sees ≥ 2 neighbours. |
| Drone-relay node | Mobile and mast relays that extend reach across distribution corridors and bridge gaps. | N+1 per corridor; Vector drones fill coverage holes. |
| Synaptic routing layer | Learns and advertises least-cost paths; recomputes on any link change. | Distributed — no controller; every node routes. |
| Transport & framing | Orders, acknowledges, and retransmits telemetry and PANACEA query frames. | Multipath; disjoint primary + backup path per flow. |
| Fabric gateway | Bridges the mesh into the PANACEA analytics layer and the Live Command Wall. | Active/active gateway pair, auto-failover. |
| Time & integrity | Mesh-wide clock sync and frame integrity so streams stitch correctly at PANACEA. | Multiple time sources; voting on disagreement. |
