OT Network Systems Specialist
Ingest MQTT Sparkplug B edge node lifecycle events including NDEATH and NBIRTH messages.
Map communication dropouts against switch topology to identify common failure domains.
Simulate recovery step sequencing to avoid reconnection storms across edge nodes.
Publish an outage post-mortem and network recovery rehearsal playbook.
Network topology graph showing edge node death timestamps, affected switch zones, and recovery rehearsal plan.
Simulated Sparkplug B telemetry packets containing seq numbers, NDEATH payloads, and bdSeq metrics. Starter examples below are synthetic. They are not downloaded records.
Eclipse Sparkplug Leverages Sparkplug B state management, particularly bdSeq counters, NDEATH payloads, and edge node lifecycle tracking.
langgraph, networkx, pydantic. LangGraph manages stateful traversal through multi-switch topology failure graphs and recovery phases. Local or hosted LLM with strong logical troubleshooting and network topology reasoning.
Submit runnable source, pinned dependencies, setup commands, a working interface, example outputs, and a recorded end-to-end demo. Include tests and an action log.
Correlates NDEATH burst events to single upstream network switches.
Validates bdSeq sequence continuity during node reconnection simulations.
Generates an ordered recovery procedure minimizing simultaneous MQTT connection spikes.
