5.5 BR Detection of RN Disconnection

During the mesh network operation, some router nodes can be disconnected due to power loss, poor signal, or other environmental factors. To understand the time required for the border router to detect this disconnection, Figure 5-14 outlines a test scenario with two router nodes connected to border router 1.

During the test, router node 2 is disconnected. The time for the border router 1 to detect this change is recorded.

When using different network configurations, change the BR and RN disconnect detection time by SysConfig as shown in Figure 5-15.

The default values for each configuration are shown in Table 5-1. These values are chosen to have less impact on the network, but a more responsive detection can be accomplished by either chosing an aggressive route refresh strategy or by other application methods.

Table 5-1 Network Configuration Default Settings For BR and RN Disconnect Detection Time
Network Configuration Default Router Node Disconnect Detection Time (in Minutes) Default Border Router Disconnect Detection Time (in Minutes)
Maximize scalability 480 90
Balanced mode 240 60
Maximize responsiveness 120 30

Table 4 outlines the time required for border router 1 to detect the disconnection of router node 2.

Network Configuration Time to Detect Disconnection (in minutes)
Maximize scalability 478
Balanced mode 238
Maximize responsiveness 119

The measured times match the default detection times set in SysConfig for each network profile considering protocol timers and measurement accuracies.
