Table 3 Key metrics for fault tolerance in MEC Systems.

From: Adaptive AI-enhanced computation offloading with machine learning for QoE optimization and energy-efficient mobile edge systems

Metric

Description

Impact

Recovery time objective (RTO)

Time taken to restore normal operations after a fault

Shorter RTO improves reliability

Failure detection rate

Percentage of faults identified before service degradation

Higher detection rates ensure seamless performance

Task completion rate

The ratio of completed tasks to total tasks

Indicates system robustness
