The Track module is used to implement collaboration of different modules by
establishing collaboration objects. The collaboration here involves three parts: the
application modules, the Track module, and the detection modules. The Track
module works between the application modules and the detection modules and is
mainly used to shield the difference of various detection modules to provide a
unified interface for application modules. When the status of a detected object
(Reaction entry) changes, the detection module informs the Track module of the
change. The Track module then tells the corresponding application module to deal
with the change accordingly. In this way, the collaboration is implemented.
You can establish the collaboration between the Track module and the detection
modules through configuration. A detection module probes a Reaction entry and
informs the Track module of the probe result. The Track module then changes the
status of the Track object accordingly. If the probe of the Reaction entry succeeds,
the status of the corresponding Track object is positive; If fails, negative.
At present, the detection modules that can collaborate with the Track module
include the network quality analyzer (NQA) only. Refer to
maximum number of history records that can be saved in a test group" on page
2029for details of NQA.
