These modules collaborate with one another through collaboration objects. That is,the detection modules trigger the application modules to perform certain operations through the Trackmodule. More specifically, the detection modules probe the link status, network performance and so on,and inform the application modules of the detection result through the Track module. After theapplication modules are aware of the changes of network status, they deal with the changesaccordingly to avoid communication interruption and network performance degradation.The Track module works between the application modules and the detection modules and is mainlyused to obscure the difference of various detection modules to provide a unified interface for applicationmodules.Collaboration Between the Track Module and the Detection ModulesYou can establish the collaboration between the Track module and the detection modules throughconfiguration. A detection module probes the link status and informs the Track module of the proberesult. The Track module then changes the status of the Track object accordingly:z If the probe succeeds, the status of the corresponding Track object is Positive;z If the probe fails, the status of the corresponding Track object is Negative.
