Cross-domain service assurance
Reason from degraded experience back to probable cause.
This research pattern connects topology, configuration, telemetry, alarms, changes, probes, incidents, and service/customer dependencies so operations could see one causal case instead of correlated noise.
The decision
Observe, reroute, restart, rollback, dispatch, escalate, or wait—and which services and customers need protection?
The evidence
RAN/transport/core/cloud/IT telemetry, alarms, topology, config and change, probes, tickets, inventory, SLA, customer experience, and weather/power.
System behavior
Suppresses symptom storms, ranks causal hypotheses, estimates impact, retrieves runbooks, simulates policy-permitted actions, executes approved steps, and verifies outcome.
Human boundary
High-risk, novel, cross-domain, security, and high-blast-radius changes require NOC/change authority. Failed verification triggers rollback.
