Track overview
Introduction to collaboration
The track module works between application and detection modules, as
Figure
46 shows. 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 respectively. 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 of 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:
• Collaboration between the track module and a detection module
• Collaboration between the track module and an application module
Collaboration between the track module and a detection module
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 normally, 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 functions abnormally, 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 Invalid.
The following detection modules can be associated with the track module:
