Overview
The Track module works between application modules and detection modules, as shown in Figure 34. It shields the differences between various detection modules from application modules.
Collaboration is enabled when you associate the Track module with a detection module and an application module, and it operates as follows:
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 application module.
When notified of changes for the tracked object, the application modules can react to avoid communication interruption and network performance degradation.
