5 Additional Test Metrics

In addition, the large-network infrastructure was used to validate several critical performance metrics of the Thread mesh network. These metrics include protocol robustness, which assesses network stability by observing factors such as device role promotion, network joining time, and mesh-healing capability.

Network performance was also evaluated by analyzing system behavior during scenarios such as simultaneous device boot-up, parent-loss events, and the associated recovery mechanisms.

Transport protocol performance was examined by comparing communication over UDP, which does not use acknowledgments, and TCP, which does.

The test setup also monitors link quality and RSSI to evaluate signal strength, link reliability, and neighbor connectivity, including the tracking of neighboring devices.
