Configuring Track

Overview

The Track module works between application modules and detection modules, as shown in

Figure 15

. It

shields the differences between various detection modules from application modules.
Collaboration is enabled after you associate the Track module with a detection module and an

application module. The detection module probes specific objects such as interface status, link status,

network reachability, and network performance, and informs the Track module of detection results. The

Track module sends the detection results to the associated application module. When notified of changes
for the tracked object, the application modules can react to avoid communication interruption and

network performance degradation.

Collaboration fundamentals

The Track module collaborates with detection modules and application modules:

The detection module sends the detection result of the associated tracked object to the Track module.

Depending on the result, the Track module changes the status of the track entry:

If the tracked object functions correctly (for example, the target interface is up or the target network
is reachable), the state of the track entry is Positive.

If the tracked object does not function correctly (for example, the target interface is down or the

target network is unreachable), the state of the track entry is Negative.

If the detection result is not valid (for example, the NQA test group that is associated with the track
entry does not exist), the state of the track entry is NotReady.

The following detection modules can be associated with the Track module:

NQA.
